II. Highlight Functions

1. Enhanced Mesh Segmentation and Display

Overview In reverse modeling a mesh is only used to describe 3D shape information, so to

make a CAD-ready model users must first divide features on the 3D shape and

recognize the design intent of each feature. The region segmentation function helps

users to automatically classify regions by estimating curvature flow on surfaces of a

mesh and categorize those regions as geometries, such as planes, cylinders, spheres,

cones and freeform shapes.

The region segmentation algorithm has been enhanced greatly in this version of the

application. This new algorithm can classify regions even more accurately, requiring

less effort of users when performing tedious region editing work such as merging or

splitting regions that are separated unclearly. Displaying regions by feature type is

also newly added in this version.

Advantages of new region segmentation Saves time compared to editing regions manually.

Displays identical geometry groups for creating a quick modeling strategy.

Saves overall modeling time for meeting deadlines.

Technical Review The User Interface has been changed in the Auto Segment function for greater ease

of use:

The Estimate button has been newly added next to the Mesh Roughness

option. It estimates a proper roughness value for target mesh.

The Merge Same Primitive Shapes option has been removed. Regions are

automatically recognized as a geometry type and merged if the merging

criteria is satisfied.

The performance for the following functions has been improved in the Auto Segment command:

Overall region segment results are now more accurate.

How the application responds to noisy mesh is now more accurate.

The generation of smooth boundary of regions has been improved.

Previous Version New Version

Region properties have been changed as follows:

Region entities are no longer displayed in the Model tree.

Region is now a mesh display method, so it is located both in the Display tab

and in the toolbar.

Display Tab Toolbar

A new display method called Geometry Type Display is added.

The icon for the “Geometry Type Display” has been added both in the

Display tab and in the toolbar.

Toolbar

Geometry Type Display shows groups of similar geometries in the same color

so that the location of planar, cylindrical, conical, conical, spherical, torus,

revolved and freeform areas of a mesh can be easily distinguished.

2. Easy and Intuitive Region Editing Tools Overview The application analyzes geometric features from scan data by classifying regions so

that they can be used to accurately and effectively model scan data. For example, if

a scanned 3D object has cylindrical or conical features, a rotational axis can be

automatically or semi-automatically extract from the feature regions. The extracted

rotational axis could also be used for creating revolved feature shapes.

The application provides an intelligent region segmentation tool to easily recognize

geometric features from scan data. It also provides various enhanced region editing

tools so that users can easily and quickly edit regions.



Function Location Tools > Region Tools

Advantages of new region tools Significant productivity enhancements.

Region editing is now easier and more intuitive.

Reduces the time needed for beginners learning to use region editing tools.

http://www.youtube.com/watch?v=D4UzZu6wvCI�



Technical Review

A new region editing command called Resegment has been added. When

regions from Auto Segment need to be split or merged with different region

segmentation parameters, the Resegment command can be used.

Original Regions Resegment

Resegments existing regions by redefining classification criteria.

Removes selected target regions and resegments the areas by using different

classification criteria.

Can be accessed in the popup menu.

The User Interface for Region Group commands has been improved for greater

ease of use.

The Append command has been removed and merged with the Merge

command.

The Remove command has been removed and merged with the Split

command.

The Merge and Split editing tools were previously used by toggling but now

work one at a time. The Split command now uses a dialog tree.

The Split command has been enhanced as follows:

When splitting regions, the polyline method is available by picking starting and

ending points on regions. However, dragging will use the current selection

option (paint, rectangle, line, etc).

When a polyline completely splits a region, the polyline color will be changed

from yellow to violet.


Split by Polyline Split Result

A region can be limited to a single region in order to not affect other regions

while splitting. Only a single region can be limited at one time.

The Mouse Helper guides users on how to use the Split tool with before and

after images.

Global options in the tool palette have been changed as follows:

Filtering Criteria has been removed.

The option for removing small cluster regions now works internally.

The Geometry Classification Option has been added.

Users can now control geometry classification tolerances to compensate for

model size and resolution using the Geometry Classification Option.

3. Auto Sketch Enhancement Overview To start reverse modeling, many sketches based on sectional polyline of scan data

need to be created in order to generate features. A sketch consists of many lines and

arcs. A lot of time can be spent creating sketches when a model contains many

complex features, which can be a very tedious operation for users.

The dramatically enhanced Auto Sketch command makes the time consuming task

of creating sketches faster and easier when drawing many sketch entities. Auto Sketch can extract parametric sketch entities from scan data intelligently based on

section polylines. A sketch can be created not only from simple features, but also

from complicated features.



Function Location Tools > Sketch Entities > Auto Sketch

Advantages of new Auto Sketch Saves a large amount of time when drawing sketches.

The often tedious task of drawing lines and arcs is automatically completed.

Select editing with Auto Sketch can create completely parametric sketches.

You can definitely save overall modeling time.

http://www.youtube.com/watch?v=03pgug4uakQ�



Technical Review The Auto Sketch command has been enhanced generally as follows:

It now generates sketch entities from mesh sections automatically and

intelligently.

The location of the Auto Sketch command in the menu and on the Toolbar

has been changed so that it is positioned at the top of the menu. Its icon has

also been changed so that users can clearly understand how it works.

Auto Sketch command in the menu Auto Sketch command on the Toolbar

The Enable Realtime Preview button has been added. Results can be displayed

in real-time without leaving the command.

Constraints are automatically applied to sketch entities according to a user-

defined Geometry Capture Accuracy.

Horizontal, Vertical, Parallel, Perpendicular, Coincidence, and Tangent are the

6 supported constraints conditions.

Some options in Auto Sketch have been enhanced for usability:

The Create Entities and Add Tangent options have been removed.

The Sew Entities option has been integrated into a new option named Sew

Tolerance.

Previous options that required specific manually inputted values have been

changed so that the values can be easily set by adjusting a slider.

New options have been added in Auto Sketch:

New methods named Make All Curves and Make Selected Only have been

added so that entire section polylines or only partially selected section

polylines can be generated while creating sketches.

The Resolution slider has been added so that the resolution of a section

polyline can be set.

Note: When adjusting this option, the segment result will be displayed on a section polyline in real-time, and its value will be synchronized with the resolution within the Segment Section Polyline Tool Palette.

A new option named Geometry Capture Accuracy has been added. This

option is used for adjusting the fitting accuracy of sketch entities.


A new option named Remove Small Fillet has been added. This removes

unwanted small fillet sketches that were automatically generated by using

radius as the criteria. After creating sketches, fillet radii can be manually

managed and fillets can be added by using the Fillet tool.


The following images shows results from the Auto Sketch function with just one

button click.

4. Quick Modeling Overview A model is a combination of various features. The common reverse modeling process

is to add, merge, or subtract features to finally generate an overall shape. We wanted

to make the reverse modeling process automatic, so we developed the revolutionary

quick modeling process for this version of the application.

RapidWorks recognizes features by analyzing regions on a mesh and users can select

an analyzed region to insert/merge, cut or fillet features. RapidWorks will

automatically decide an optimized sketch and then create features by extrusion,

revolution, fitting or filleting. Repeating the semi-auto modeling can help to

complete an entire model or edit features with less time than it would take to create

all features manually from a base scan.



Function Location The quick commands are located in the popup menu that is displayed by clicking

the right mouse button while hovering the mouse cursor over a segmented region in

a selection mode.

http://www.youtube.com/watch?v=09ugIZRDYDc�



Advantages of the new Quick Modeling commands Beginners without knowledge of RapidWorks can model.

Saves time needed for feature generation.

Ambiguous features of extrusions or revolutions can be defined by computer

calculation.

Quick access to feature creation commands by using the new popup menu.

Technical Review General usage and convention of quick modeling:

Quick modeling can be accessed by picking a region and using the popup

menu.

Commands connected with quick modeling are the Extrusion Wizard,

Revolution Wizard, Fillet and Mesh Fit commands.

Single regions can be selected for quick modeling.

Multiple regions can be selected for quick modeling.

Regions can be added or removed while quick modeling.

The application will intelligently run different Modeling Wizards according to

the feature shape used.

Automatically created features are registered in the Feature Tree and its

composition features can be edited.

The following functions are available in the popup menu:

Insert/Merge: Creates a new feature and merges features if other features

exist.

Cut: Removes a feature from existing features.

Fillet: Applies Fillets to features.

Insert Sketch: Does not generate a feature but creates sketches automatically.

Extrusion type feature shape:

When an extruded feature shape is recognized from selected regions, the

Extrusion Wizard will automatically run and find target regions on all sides.

The best extrusion direction for creating a feature correctly is recommended

from extrusion direction candidates analyzed from the target regions.

Note: A sketch base plane will be automatically generated along a user-defined extrusion direction.


If a Ref.Plane already exists and its normal direction corresponds with a user-defined extrusion direction, the sketch base plane will be generated offset from the Ref.Plane. When the offset distance is small, the existing Ref.Plane will be used as a sketch base plane.

Revolution type feature shape:

When a revolved feature shape is recognized from selected regions, the

Revolution Wizard will automatically run and finds similar connected target

regions. A proper revolution axis will be automatically extracted from the target

regions for creating features correctly. The revolution axis will be previewed by

a construction line in the first stage and it will be automatically changed to a

Ref. Vector in the second stage.

Note: If the Revolution Wizard is executed by clicking the Revolution Wizard button in the Toolbar or by going to Insert > Modeling Wizard > Revolution Wizard in the menu, the revolution axis will not be previewed.

Freeform type feature shape

When a freeform feature shape is recognized from selected regions, the Mesh

Fit command will automatically run and find target regions for creating

features.


How to Use 1. Import a mesh and then segment regions from it.

2. Select a region as a seed region for creating a feature shape.

3. Click the right mouse button and choose Insert/Merge from the popup menu.

4. The Extrusion Wizard command will automatically open. Check the regions are

selected in each side, which require for creating a feature shape to see that the

application automatically detected the proper extrusion direction.

Note: If needed, more regions can be manually added on each side for creating a feature shape.


5. Click the Next Stage button . Adjust the Resolution option until satisfactory

results are achieved.

6. Check the preview and click the OK button to confirm the results.

7. Using the same methods, cut four cylinders off of the corners by choosing Cut from the popup menu.

8. Check the result.


5. Auto Surfacing Enhancement Overview The Auto Surfacing command automatically generates patch networks and fills

surfaces by using advanced fitting algorithms and finally sews and matches the

surfaces. This is a quick method to generate NURBS surface from scan data.

The Feature Following Network method is highly enhanced. Now Auto Surfacing

makes much better following curve networks and creates less defective faces. Users

can easily find erroneous areas in a network and quickly change focus to each

erroneous curve by using the back and forward navigation buttons.



Function Location Insert > Surface > Auto Surfacing

Advantages of the new Auto Surfacing The degree of freedom while editing patch network has been increased.

The fitting success rate has been increased for better results with various model

shapes.

Errors are displayed in real time while patch network editing.

Technical Review General enhancements in Auto Surfacing:

The Auto Surfacing command now supports multi-core CPUs when surface

patches are generated on a mesh. Its performance has been enhanced and the

calculation time is much faster

The fitting success ration on thin and long patch around boundaries has been

increased.

A new option named Hole Filling By Area has been added in the Patch

Network Options. Target holes from holes on mesh can now be manually

distinguished, which can be applied to hole filling by using area as the main

criteria.

Enhancements of the Evenly Distributed Network method:

The Evenly Distributed Network method can now estimate the proper number

of surface patches from a target mesh. The Estimate button has been added

next to the No. Of Surfaces option.

Shortcut keys and a popup menu are now available in the second stage. The

editing methods can be quickly changed by pressing the shortcut keys or by

choosing a method in the popup menu.


Erroneous patches, such as inappropriate angles between neighboring edges or

missed patches after generating fitting surfaces are now highlighted in red

when the results are previewed and restored.

Enhancements to the Feature Following Network method:

The Feature Following Network method makes a more CAD-like patch

network and creates less defective faces.

Patch editing performance is much faster and more responsive than previous

version.

Shortcut keys and a popup menu are now available in the second stage. The

editing methods can be quickly changed by pressing the shortcut keys or by

choosing a method in the popup menu.

The Mouse Helper guides how to use editing methods such as Split, Slide,

and Swap Y and T Junction, with before and after images.


Split Slide Swap Y and T Junction

The Feature Following Network method includes new editing options:

Slide – The name of the Detach And More method has been changed to

Slide. It repositions the starting or ending point of a spline to another position.

Pick a spline first and then pick the position on another green spline.

Before Slide After Slide

Swap Y and T Junction – A new method named Swap Y and T Junction has

been added. This method swaps a Y junction with a T junction. Splines able to

be swap will be displayed in green. If a green spline is chosen, the T junction

mark will be swapped to a Y junction.

Note: T-junctions are junctions where one spline joins another but does not cross it and is marked by thick lines at the intersecting node as shown in the right image. Surfaces matching around a T-junction may not be able to be used for auto surfacing, so it is better to remove them or add a spline to make a completed junction.

A Y junction consists of three splines and T junction consists of two splines.

Y Junction T Junction


If a patch consists of a Y and T junction and the T junction is located at a

corner of a rectangle, the rectangle does not contain four correct edges.

By swapping Y and T junctions, this rectangle will have four correct edges.

Before Swap After Swap

Quick Preview – A new option named Quick Preview has been added. This

option quickly displays preview results without calculating matching and sewing.

Show Erroneous Patches – A new option named Show Erroneous Patches

has been added. This option shows erroneous patches such as inappropriate

angles between neighbor edges or missed patches after generating fitting

surfaces.

Erroneous patches will be highlighted in red. The thin red patches shows errors

that have inappropriate angles between neighbor edges. The thick red patches

shows errors that will cause fitting surfaces on mesh to fail or generating

surfaces from a constructed curve boundary to fail. These patches are updated

after applying a preview.

Show Nodes And T-junctions – A new option named Show Nodes And T-

junctions has been added. This option displays relevant nodes and T junctions

on patches.

Show Nodes and T Junctions Hide Nodes and T Junctions

Show Defined Sharp Edge – A new option named Show Defined Sharp

Edge has been added. This option displays sharp edges if edges exist that are

defined by using the “Define Sharp Edges” method.

Deform With Stiffening Around Crossing Nodes – The name of the Apply

Stiffening Around Crossing Vertices option has been changed to Deform

With Stiffening Around Crossing Nodes. This option is applied while patches

are deformed. It deforms patches by stiffening around crossing nodes.


6. Fillet Selection Guide Overview Filleting make rounded faces at sharp edges and is normally the final stage to

complete a feature or a model. If a model is very complicated or includes many

features, the number of edges will also be very high. To properly complete a model,

users need to find edges with the same fillet radius and apply them to all

appropriate edges without missing any on the CAD model.

A new option named Selection Guide has been added to make this process easier.

This option helps users to easily add fillets to a body. When a fillet radius in input in

the Fillet command, RapidWorks will find and highlight edges with the same fillet

radius by analyzing the connecting mesh to a selected edge on a CAD model. Fillets

can be applied to complex edges by using the selection guide.



Function Location Insert > Modeling Feature > Fillet: Selection Guide

Advantages of the Fillet Selection Guide Selects areas with the same round edge value when applying a fillet.

Can apply fillets without missing edges.

Makes applying fillets easier on complex models.

Technical Review General usage and convention of Selection Guide:

The Selection Guide option works under the Constant Fillet method.

Similar fillet edges are highlighted in real-time as a user inputs a radius.

When a lot of candidate edges are highlighted, a slider can be used to limit the

maximum number of highlight edges.

http://www.youtube.com/watch?v=rII4HCZGM_Q�



Applicable for different fillet group.

While the Selection Guide option is on, only highlighted edges can be

selected by the dragging selection method. This helps to quickly select specific

target edges in the view. However, if edges are manually picked, any edges can

be selected.

How to Use 1. Prepare a mesh and a body.

2. Go to Insert > Modeling Feature > Fillet in the menu.

3. Choose the Constant method.

4. Pick an edge on the body and click the Estimate Radius From Mesh button to

get a recommend value from the mesh.

5. In this example, the estimated value is 0.731mm but 0.7mm in input as a guess

to the original designer’s intention.

6. Check the Selection Guide option to see other edges that have a fillet radius of

0.7 mm.

7. Select highlighted edges.

8. Click OK to confirm result.


7. LiveTransfer™ Enhancement Overview To export a CAD model from RapidWorks to another CAD system with geometry

information, including parametric information, is an important process to seamlessly

connect design and manufacturing processes. The LiveTransfer™ function can export

geometry and parametric information as well as modeling history to other CAD

systems.

Now the LiveTransfer™ command supports Autodesk Inventor. Inventor users can

import model data with its parametric information from RapidWorks to Inventor

where they can edit and change feature parameters.

Additionally, the supported CAD version has been updated.



Function Location File >LiveTransfer™ > To Inventor

Advantages of LiveTransfer to Inventor Inventor users can import parametric reverse engineering data from

RapidWorks.

Saves efforts when transferring data into a CAD system.

5. Mesh Tools (1) Enhanced Smooth command in Mesh Tools

The Smooth command in Mesh Tools has been enhanced as follows:

Removed options The Strength option has been integrated into the Smoothness Level option.

Now the smoothness level can be effectively controlled and apply to a mesh.

The Do Not Modify Sharp Edges option has been removed and replaced with a

new option.

Added options A new option named Feature Preservation has been added. This option

replaces the Do Not Modify Sharp Edges option. With this option, smoothness

can now be applied to mesh, which preserves feature shapes


(2) Reduced default extension area in Rewrap command

The default extension area in the Rewrap command has been adjusted to be reduced.

As well, the extension area can be limited by adjusting a manipulator. This makes the

calculation time much faster than in previous versions.

Previous Version

New Version

Note: The volume manipulator appears when the Extend Boundaries option is enabled. This is useful when dealing with a mesh which has boundary shapes opened toward the outside.

6. Region Tools (1) Enhanced setting method for the geometry types of regions in the

Region Group mode

Classification methods for the geometry types of regions have been enhanced. The

Geometry Classification Option is a new Tool Palette in the Region Group mode

that specifies a tolerance and outlier for checking the geometry types of regions.

Note: The default value of geometry tolerance will be determined according to the size of a target mesh.


Additionally, manual specification of the geometry types of regions can be set in the

Properties.

7. Point Cloud Tools (1) Newly added Separate Point Cloud

A new point cloud tool named Separate Point Cloud has been added in the Point

Cloud tools. This tool divides several groups of point cloud and separates them from

an original point cloud.

This tool is useful for separating parts of a point clouds from an original point cloud

and when dealing with large point clouds.



(2) Large Point Cloud Performance Enhancements

When using large point cloud data files such as data from a long range scanner,

drawing and selection performance has been improved.

http://youtu.be/jOHxlRhE790�



Drawing Speed The drawing speed of a large point cloud is now about two times faster than the

previous version. This is noticeable especially when using multiple large point

clouds, as the drawing performance has been exponentially improved.

Static Display Quality When displaying a large point cloud in a static status, its drawing quality has

been improved for clear shape recognition. Now more realistic details will be

displayed.


Selection and Display When selecting points from a large point cloud, shading using normal is still

available on selected points. This allows for the easy recognition of shapes in the

selection area.


Selection Performance When selecting points using the through all method, the selection speed has

been enhanced. A bug that caused missing points within the selection area has

also been fixed.

Behind Points Display When the display status of points in a large point cloud is set to Transparent,

Depth or X-Ray, and the vertex size was zoomed in or out, points in the back

were drawn in front of the points in the front. This bug is now fixed and models

with have correct visual depth.


8. Ref.Geometry (1) Changed “Intersect Line and Face” method in the Add Ref. Point

command

The name of the Intersect Line and Face method has been changed to Intersect

Line (Curve, Axis) & Face. Now, a Ref. Point can be created by intersecting any axis-

type geometric entity with a Ref. Plane or a planar body face. A line or any

geometric entity that has an axis like cylinder, cone, or torus can be a target entity of

the line.

(2) Newly added Flip Direction button in the Add Ref.Coordinate

command

The Flip Direction buttons for each coordinate axis have been added in the Pick

Multiple Points and Pick Point & 2 Lines methods of the Add Ref. Coordinate

command so that the directions of coordinate system that have been set according

to a user-defined order can be flipped. These buttons can be used while a Ref.

Coordinate is previewed.

9. Sketch (1) Enhanced segmentation of section polyline

The resolution level and segment shape of a section polyline have been highly

enhanced. The enhancements are as below:

When segmenting section polylines, the application now supports multi-core

CPUs to get results much faster.

The Max. Arc Radius option in the Toolbar has been removed. Now, the

geometry types of section segments are automatically determined without

specifying a maximum arc radius while adjusting the slider in the Segment

Section Polyline Tool Palette.


The method of segmenting section polylines has been changed so that it can

be freely adjusted using the slider in the Resolution option. When adjustments

to the slider are complete, the section polyline will be segmented.

The default position of the slider in the Resolution option has been changed to

be in the middle.

Note: The enhanced segmentation of a section polyline is applied in various cases such as;

When using section polylines in the Mesh Sketch mode

When estimating values in the Fillet and Chamfer commands by clicking the Estimate button

When estimating a radius in the Conic Fillet option while the Variable Fillet method of the Fillet command is applied by clicking the Estimate button

When using the Exclude Round Corner option in the Mesh Sketch Setup command

When creating profile curves in the Extrusion, Revolution, Sweep and Pipe Modeling Wizards

(2) Enhanced Corner Trim method in Trim command

The Corner Trim method has been enhanced so that sketches are quickly trimmed

by click-dragging like the Power Trim method.

Before Trimmed After Trimmed

(3) Enhanced calculation speed of the Fit From Point command

The calculation speed of the Fit From Point command has been highly enhanced

and the Sampling Ratio option has been newly added in More Options so the

sampling ratio can be specified when the Fitting Shape is set to Freeform. The

sampling uses an Auto ratio by default but can be set as desired.


(4) Newly added Smart Snap function

A new snap function named Smart Snap has been added in the Sketch Options.

This function enables easy snapping of sketches to a section polyline while drawing

the sketches. This function can be toggled by clicking the SmartSnap button in the

toolbar or choosing Tools > Sketch Options > SmartSnap in the menu. It can also

be activated by pressing the Shift key while drawing sketches.

Snap to Section Polyline Sketches Snapped on Section Polyline

Additionally, when drawing sketches on a section polyline, the Mouse Helper guides

on how to use the Smart Snap function.

10. Surface / Solid (1) Changed button name in the Datum Alignment method of the

Transform Body command

The button name used in the Datum Alignment method of the Transform Body

command has been changed from Datum Pairs to Datum Pairs – Type (Moving –

Target, Flip) to make how the datum alignment works with specified datum pairs

clearer.

(2) Newly added lock button in Extrude command

A lock button to keep the command running after clicking OK has been newly

added in the Extrude command.


This enables the creation of multiple bodies from a base sketch by continually re-

defining different sketch profiles without leaving the command.

(3) Enhanced Extrusion Wizard

The Extrusion Wizard has been enhanced as follows:

Newly added Expand Section button

A new button named Expand Selection has been added next to the Sides

option so that target regions can be easily found for creating an extruded feature

shape. If a seed region is selected, this button will be enabled and will

automatically find target regions that require the creation of an extruded feature

shape.

Newly added Estimate button

An Estimate button has been added to estimate an extrusion direction from

selected target regions.

Removed options

The Use Specific Direction As Initial Guess option has been removed and

the Use Specified Direction As It Is option has been integrated into the

Custom Extrusion Direction option. When a custom extrusion direction is

specified, a feature will be generated along the specified custom extrusion

direction as it is.


The Freeform Curve(s) option under the Profile Auto Generation

Options has been removed and the Profile Auto Generation Options

except the Freeform Curve(s) option have been moved to the second

stage and divided into the Resolution, Geometry Capture Accuracy, and

Sewing Tolerance options. The Extrusion Wizard fully supports 2D

analytic sketches only, with a highly enhanced auto sketching function.

The Cap Ends option in the second stage has been removed and

integrated into the Result Operator option.

The Manual Section Polyline option in the second stage has been

removed. The Extrusion Wizard automatically creates a virtual sketch base

plane and extracts section polylines from the target regions on the sketch

base plane. If a plane is specified by using the Fix Sketch Plane With

Selection option in the first stage, the plane will be used as a sketch base

plane.

Added options

The Result Operator option in the second stage has been moved to the

first stage and changed so that results can be specified. If other bodies

exist already, Boolean operation with the existing bodies can be applied

while creating extruded features. The Result Operator offers the Solid

Insert, Solid Merge, Solid Cut, Surface Insert, and Surface Cut methods.

Note The Result Operator option shows sub options differently depending on the type of existing body. It determines how to use a resulting body that is related to the existing solid or surface body. Solid Insert – A resulting body will be inserted as a new solid body. Solid Merge – A resulting body will be merged into an existing solid body. Solid Cut – An existing solid body will be cut by a resulting solid body Surface Insert – A resulting body will be inserted as a new surface body. Surface Cut – An existing solid body will be cut by a resulting surface body

The Remove Small Fillet option has been added in the second stage. This

option removes automatically generated small fillet features by using the

criteria of radius value. After creating an extruded feature, the fillet radius

can be manually entered and fillets can be added to the body by using the

Fillet command.


(4) Enhanced Revolution Wizard

The Revolution Wizard has been enhanced as follows:

Newly added Estimate button

The Estimate button has been added to allow estimating a revolution axis from

selected target regions.

Removed options

The Use Specific Direction As Initial Guess option has been removed.

The Use Specified Direction As It Is and the Use Specified Axis Of

Rotation As It Is options can be used to specify a direction or a rotation

axis from a user-defined custom revolution axis.

The custom revolution axis now can be specified by 2 planes. When

specifying a custom revolution axis by using 2 planes, an intersected line

will be specified as the revolution axis and a sketch base plane will be

automatically defined on a higher priority plane from the specified 2 planes.

Note

The higher priority plane is determined by order of registration in the Feature Tree. For example, if Base Ref.Plane is selected and a user-defined Ref.Plane is selected as the target planes for defining a revolution axis, the Base Ref.Plane, which is higher priority plane in the Feature Tree, is determined as the sketch base plane.

If 2 user-defined Ref. Planes are selected as the target planes, the plane created first will be set as the sketch base plane.

The Freeform Curve(s) option under the Profile Auto Generation

Options has been removed and the Profile Auto Generation Options

except for the Freeform Curve(s) option have been moved to the second

stage and divided into the Resolution, Geometry Capture Accuracy, and

Sewing Tolerance options. The Revolution Wizard fully supports 2D

analytic sketches only, with a highly enhanced auto sketching function.

The Cap Ends option in the second stage has been removed and

integrated in the Result Operator option.

The Manual Section Polyline option in the second stage has been

removed. The Revolution Wizard automatically creates a virtual sketch base

plane and extracts section polylines from the target regions on the sketch


base plane. If a plane is specified by using the Fix Sketch Plane With

Selection option in the first stage, the plane will be used as a sketch base

plane.

Added options

The Result Operator option in the second stage has been moved to the

first stage and changed so that results can be specified. If other bodies

exist already, Boolean operation with the existing bodies can be applied

while creating extruded features. The Result Operator offers the Solid

Insert, Solid Merge, Solid Cut, Surface Insert, and Surface Cut methods.

Note The Result Operator option shows sub options differently depending on the type of existing body. It determines how to use a resulting body that is related to the existing solid or surface body. Solid Insert – A resulting body will be inserted as a new solid body. Solid Merge – A resulting body will be merged into an existing solid body. Solid Cut – An existing solid body will be cut by a resulting solid body Surface Insert – A resulting body will be inserted as a new surface body. Surface Cut – An existing solid body will be cut by a resulting surface body

The Remove Small Fillet option has been added in the second stage. This

option removes automatically generated small fillet features by using the

criteria of radius value. After creating an extruded feature, the fillet radius

can be manually entered and fillets can be added to the body by using the

Fillet command.

Enhanced Auto Sketch function

The Auto Sketch function has been enhanced so that a closed sketch profile is

automatically constructed when a target result is specified as a solid body.

11. Measure (1) Snappable section planes

The N-Division Between Planes method has been enhanced when measuring

sections that the sections can be snapped onto a pre-defined plane that is parallel

to the Base Plane while manipulating its position. This is useful to exactly set the

section plane on a pre-defined plane.


IV. Fixed Bugs

1. Major bugs When RapidWorks does not work normally the issue will be classified as a major bug.

User Interface

(1) Continuity of Accuracy Analyzer

When Curvature was selected as the Continuity in the Accuracy Analyzer, the

application would crash occasionally. The bug has been fixed.

(2) Display tab

When Transparent was checked and Depth or X-ray was selected as the Point

Shader in the Display tab, the display of point depth was incorrect. The bug has

been fixed.

(3) Using a comma (,) in a German OS

Commas were not recognized as a decimal point and calculations using a comma

obtained wrong results. Importing a file with commas was also not possible. The bug

has been fixed.

A sketch created by the Revolution Wizard would not transfer to SolidWorks. The

bug has been fixed.

(2) Transferring a mesh sketch created by Rotational Method to

SolidWorks

A mesh sketch created by the Rotational Method with a user-defined central axis

and base plane that were not laid on same plane would not transfer into SolidWorks.

The bug has been fixed. When automatically generating a sketch in SolidWorks, a

virtual plane that is used as a sketch base plane will be automatically created.

(3) Transferring a cube with a sketch to Siemens NX

When a cube with sketch on the planes was transferred to Siemens NX, the direction

of the sketch was changed in Siemens NX. The bug has been fixed.

(4) NX crash caused by the Replace Feature

Siemens NX crashed if LiveTransfer™ tried to transfer a static body using the Replace

Feature to Siemens NX. A message showing a pause status is now displayed.

(5) Transferring a draft feature to Siemens NX

When a draft feature based on a face was transferred to Siemens NX, the draft angle

was reversed. The bug has been fixed.

(6) Restarting a transfer to Siemens NX or Creo(Pro/E)

If LiveTransfer™ restarted a transfer to Siemens NX or Creo(Pro/E) after pausing,

restarting would lock. The bug has been fixed.


Batch Process

(1) Cancel button of Batch Process

All buttons in a dialog box to quit a batch process saved the process even if the

Cancel button was selected. The bug has been fixed.

(2) Naming rule of a new Batch Process

moved, the bars became white or the cursor would handle abnormally. The bug has

been fixed.

Point Cloud Tools

(1) Range of filtering box

If Filter Outlier Regions and Filter With Box Volume were selected in Tools >

Point Cloud Tools > Filter Noise, the range of the filtering box was abnormal. The

center point and size of the filtering box has been fixed. The center point of the

filtering box is now fitted on the center of a bounding box and size of the filtering


box is 1.2 times the size of the bounding box.

(2) Copy and paste

When points of mesh were copied and pasted, boundary vertices and extra vertices

around the boundary were copied. Only selected vertices are copied now as a new

shell.

Alignment

(1) Normal direction of Tools > Scan Tools > Align Between Scan Data

The normal direction would change when Local Base On Auto Guess or Local

Based On Picked Point was selected to align a point cloud. The bug has been fixed.

(2) Alignment of a suppressed mesh

The application would crash when a suppressed mesh was aligned by the Global

and Fine option in Tools > Scan Tools > Align Between Scan Data.

The bounding boxes of a suppressed mesh and unsuppressed mesh were also not

updated and would remain. The two bugs have been fixed.

(3) Updating the histogram of the Align Between Scan Data command

The histogram did not display the value of the Max and Average Deviations when

the Update View & Histogram option was checked with the Global And Fine

option. The bug has been fixed.

(4) OK button of Align Between Scan Data

The OK button was not activated after the Apply button was clicked several times

without changing the values of Tools > Scan Tools > Align Between Scan Data. The

bug has been fixed.

(5) Undo of Align Between Scan Data

When Local Based On Auto Guess and Global And Fine options were used in that

order, undo by using Ctrl +Z had problems.

If undo was executed twice, the undo created the original status. If the two options

were used again, the alignment would become dislocated. The bug has been fixed.

If the value of the Max. Average Deviation was larger than the value of the Estimate

and undo was executed once, there was no response from RapidWorks. A message

showing it is not a proper condition for alignment is now displayed.

(6) Rollback and Alignment Between Scan Data

If Rollback was executed and Align Between Scan Data was executed, the

alignment influenced the last feature even though a Rollback was executed. The

bug has been fixed.


(7) Undo of Update View & Histogram

If an undo was attempted when Update View & Histogram was checked in Tools >

Scan Tools > Align Between Scan Data > Global and Fine, the histogram was not

updated. The bug has been fixed.

(8) Histogram after canceling Best Fit

If Best Fit was canceled, the corresponding process should be also canceled,

however, the process remained and the histogram did not appear. The bug has been

fixed.

(9) Picking points for Align Between Scan Data

When Local Based On Picked Point was used with Refine Alignment, scan data

was not aligned. The bug has been fixed.

(10) Normal direction of point clouds

The normal direction of point clouds was reversed by the following commands:

The bug has been fixed.

(11) Transformation of point clouds

When point clouds were transformed by the following commands, the point cloud

would disappear:

Tools > Align > Interactive Alignment Tools > Scan Tools > Transform Scan Data


(12) Transform Alignment

The normal or a mesh would get broken when the matrix to transform had non

uniform scaling. The bug has been fixed.

Region Tools

(1) Preserve Existing Regions option of the Auto Segment command

The Preserve Existing Regions option of the Auto Segment command didn’t work.


(2) Regions of Small size

The Region Group command made incorrect regions when the size of the region

was small. The bug has been fixed.


Ref. Geometry

(1) Target of Add Ref. Point when an arc edge is selected

An arc edge can be considered as a part of a circle; when an arc edge was selected,

Add Ref. Point command selected the center point of circle but the selected edge

as the target.

The target can be controlled by Ctrl key now. Add Ref. Point selects the edge

without Ctrl key and a center point of circle with Ctrl key.

(2) Adding Ref. plane

Adding two Ref. planes with the Extract method created a problem. When the

second Ref. plane was created after the first plane was added by extracting from

multiple region groups, the first setting remained. The bug has been fixed.

Sketch

(1) Mesh sketch using CMM data

Close points less than 0.005 mm from a CMM could draw a mesh sketch. The bug

has been fixed.

(2) Mesh Sketch Setup and Section of 3D Sketch

From the Connection Tolerance and Searching Depth options, the Connection

Tolerance option didn’t work when a point cloud was used. The bug has been fixed.

(3) Sketch status between an editing mode and a creating mode

The sketch status between an editing mode and a creating mode was different even

though the sketch was same. The bug has been fixed.

Surface

(1) Surface Offset

When the Make Side Wall and Remove Original Faces options of the Surface

Offset command were used to select a face for a surface offset and the face had no

side wall, the options failed. The options are now hidden when there is no side wall.

(2) Trimming of Bodies generated by Auto Surfacing

When trimming surface bodies generated by the Auto Surface command with the

Feature Following Network method by using Ref.Plane, the specified remaining

bodies and the actual results were different. The bug has been fixed.

(3) Crashing of Auto Surfacing

The application would crash if the Evenly Distributed Network was selected for

Auto Surfacing and the No. of Surfaces of the Curve Network Option was

entered as 20,000. The bug has been fixed.

If multiple regions were used for the Mesh Fit command, the 2nd and 3rd steps

would not work. The bug has been fixed.

Solid

(1) Split Face

The application might crash when the Projection method with a Single Direction

was used in the Split Face command. The bug has been fixed.

(2) Move Face

When several faces were moved by the Move Face command, the command

replaced the distance of a previously moved face to the distance of the following

moved face. The bug has been fixed.

(3) Pull Direction of Silhouette

When attempting to edit a split face created by Silhouette the Pull Direction

option disappeared. The bug has been fixed.

(4) Extrusion wizard

The Extrusion wizard has several stages. When navigating between the first step and
