Construction Geometry

Construction geometry is created within a

sketch to aid in profile creation. Only

standard geometry will be used forcreating solids or surfaces (Fig.1)

Construction geometry is shown in

dashed format. To convert an element

into a construction element, select it and

activate the option” for construction”.

You can also toggle any construction

elements from construction to standard

by deselecting the option.

Constraining the sketch

• Dimensional Constraints

(click the icon, then select the element(s))

• Length

• Distance

• Angle

• Radius/Diameter

Remark: To discontinue the command, click

the icon again.

• Geometrical Constraints

(multi-select the two elements by

pressing “CTRL” key and click the icon)

• Perpendicularity

• Horizontal/Vertical

• Concidence

• Tangency

• Symmetry (multi-select the elements on the

both side and then select the centerline)

You can also create constraints with othersketches and 3D elements out of the sketch

View Orientation• By default, the screen is parallel to the

sketch support.

• To making constraints between the sketchgeometry and the 3D element, you mayneed to rotate the model into a 3D view.

• To return the default orientation, press“space” key on the keyboard to activate themenu of orientation, and then select “Normal

to” (the viewpoint normal to the sketch plane)

We can create a distanceconstraint between the circle

centre and the solid edge

3D Sketch3D Sketch (Draw a sketch in 3D space; you don‟t need to

create a plane before creating a 3D sketch)

Build a 3D Sketch:-

•Click “3D Sketch” Icon

•Draw a profile (with lines, curves and/or axis)

(Remark: if you switch the viewpoint to Front View, the

sketch plane will be “Front Plane”; similar for other

viewpoints)

(Remark: 3D sketch can be a non-planar curve)

•Add geometrical constraints (relations)

•Add dimensional constraints & modify the values

•Click “3D Sketch” icon again to exit

Projected CurveSketch onto Face(s) (project a sketch onto a face. Theprojection can only be along the normal of the sketch)

Along the normalof the sketch

Limitations:

(1) Only planar sketches can be projected

(2) You cannot select other projectiondirection than the normal of the sketch

You can project it onto a faceof a surface or a solid

Part /Assembly Drawings2D Drawing




A- 45

Part /Assembly Drawings

We can create a 2D drawing from a part

or an assembly. They have the parent-

and-child relationship; 3D model is the

parent and the drawing is his child. If the

3D model is changed, the drawing will be

changed automatically.

The file extension of Solidworks drawings

is *.slddrw, no matter it is a part drawingor an assembly drawing.

Same as the assembly file, the drawing

file cannot be opened properly if the

system cannot locate the part/assembly

file.

Wherever when we open the drawing file,

the system will try to locate the parent

part/assembly file to update all the views.

It is unidirectional arrow; 3D canchange 2D, but not vice versa


Create Views2D Drawing




A- 46

Create Views

To create a 2D drawing:-

•Select “File/New…” on the menu

•Click “Drawing” and then OK

•Select a template, e.g. A-4 Landscape

•Click “Browse”, the select a part /assembly file

•Then Select “Single View” or “Multiple Views” (Single view – create

views one by one and we can see the preview; Multiple Views – create

many views at one time by highlighting the view icons below)

•If you want to scale down the view to fit it onto the paper, you can use“Custom size”. But generally, we prefer using a bigger paper to making

the model views smaller.

To change the properties of the 2D drawing:-

•Right-click on the paper and then select “Properties”

•We can now change the paper size and also change the projectionmethod. (By default, First Angle projection is used. First Angle

projection is commonly used in China, but Third angle projection is

used in United states and Taiwan.)

•(Remark: After the projection method is changed, all existing views will

be updated correspondingly)


Create Views2D Drawing




A- 47

Create Views

To remove all tangent edges on a view:

-Right-Click on the view

-Select Tangent Edge/ Tangent Edges Removed

To show hidden edges on a view:•Single Click on the view•Select “Hidden Lines Visible”

on the pop-up window on the left

To add or remove curves on a view:

(For dependent curves, projected from 3D)

-We can only hide the curve that we don‟t want to see. Wecannot delete it.

-To hide the curve, right-click on the view and then select

“Hide edge” then select the curve

(For independent curves, created on the view)

- Simply select and delete it.

To create a section view:

-Double-click the parent view

-Select “ insert/ Drawing View / Section” on the menu bar

-Pick two points to define the mirror line


Dimensioning2D Drawing

DimensioningTo Create Dimensions on a view:-

•Click “Smart Dimension” icon

•Select an entity / entities to dimension

•Remark: Type of dimension (distance, length, angle, diameter) is

automatically selected

•To add a tolerance, select the dimension and then change the type of

tolerance, e.g. LIMIT or Symmetric

•To add a text before or after the dimension, type in the text before or after

<DIM>

To change the dimension properties of the sheet:-

•Select “Tools /Options” on the menu bar

•Select “Document Properties”

•Select “Detailing / Dimensions”

•Change the arrow style to “closed filled”

•Select “Precision…” to increase/decrease the number of decimal

places

•Select “Detailing /Arrows” to change the arrow size

• Define “Length” and “Width” as the driving parameters,

“Height” as the driven parameter.• Select “Tools /Equations” on the menu bar

• Click “Add..”

• Double-click the feature to show all related parameters

• Select the driven parameter

• Type „‟=“

• Select a driving parameter, then type “-”

• Select the other driving parameter, then click ok• (The equation is added. Now the parameter “Height” is driven

by “Length” and “Width”

To Create a Design Table to control parameter(s):-
