Electrical Harness Installation in a Nutshell

Electrical Harness Installation is a product dedicated to the design of physical harnesses within the context of the 3D mock-up.Users benefit from electrical designs totally integrated into the mechanical assembly.This product provides a set of objects including both mechanical and electrical properties.

Electrical Harness Installation offers the following main functions:

● the bundle segment creation in Product documents (Electrical Harness Assembly workbench)

● the geometrical bundle creation

● the bundle segments properties definition

● the creation of electrical links between bundle segments and devices

● an algorithm simulating the bundle segment shape and offering realistic bundle segment representations.

● the use of supports to constraint bundle segments.

Only the following can be selected to become a geometrical bundle: ● a product which is not already electrified

● a product which doesn't result from the New Part command

● a product which doesn't result from the New Component command (inline product).


Creating a Bundle Segment Document This task explains how to create the document in which the bundle segment will take place. The bundle segment belongs to a part document with electrical properties.

To create and route a bundle segment, you need to:

● define the construction constraints

● define the bundle segment parameters

● then define the bundle segment route.

The document now contains a geometrical bundle.

1. Double-click to activate the desired product: Geometrical Bundle1

2. Click the Bundle Segment button .


The bundle segment document is created with the BundleSegment1 product including: ❍ the Bundle Segment1 part that becomes active

❍ the Flexible Curve.1 belonging to the part, which at that time, does not have any geometrical representation

As an alternative, you can select the Bend Radius Ratio option and set the ratio: the Bend

Radius is automatically computed.

4. Select the Mode: for example Slack and give a percentage of slack.


The different options are: ❍ Slack:

the bundle segment length is increased by the percentage indicated in the Slack(%) field. The Length field is disabled.

❍ Length:the bundle segment length is indicated in the Length field. The Slack(%) field is disabled.

❍ Bend:the bundle segment length corresponds to the minimum distance between the points defining its route. The Slack(%) and Length fields are disabled.

At this stage, the bundle segment parameters are defined.

You now need to route the bundle segment to be able to complete the definition: through this

operation, you will create the geometrical representation of the Flexible Curve.

Note that OK and Apply are deactivated.

5. See the next task which explains how to route the bundle segment according to the geometrical

constraints.

● The Bend Radius value must be at least equal to the Diameter value to ensure the correct bundle segment route computation.

● When you create a bundle segment on a part (keeping associativity between the bundle segment and the surface):

❍ the Bundle Segment on Surface option is activated and lets you change the side on which the bundle segment will be created.To do so, click the Reverse button.

❍ the bend radius and the build mode parameters (Mode, Slack(%) and Length) are not taken into account. These parameters are disabled.

❍ the local slack management is not taken into account either. This command is disabled.

● When you create a bundle segment on a part surface, the slack management either is not taken into account.


Defining the Segment Route Constraints

This section explains the different ways you can route a bundle segment:

● using points, devices and supports

● following a part/surface (first method using a manipulator)

● following a part (second method keeping associativity with the part)

● from an existing helix

Refer to Detailing the routing options... to know all about the More >> button.

In case of computation error, see Sharp bending bundle segment computation error.

The Tools -> Options menu lets you define if the bundle segments belong or not to a geometrical bundle. Refer to the Electrical Harness Installation Options.

Also make sure the following option is checked to take advantage of the associativity between the construction points or part body and the bundle segment.

See more information about the Options.



The Bundle Segment Route Definition dialog box closes and the Bundle Segment Definition is displayed afresh.

Note that OK and Apply are now activated.


The bundle segment is created

Note that two objects turned to red, which indicates that they need to be updated: They are adaptative parts.See Creating Adaptative Part.

5. Double-click the root product: the geometry is updated.

Note: if the Automatic update is not activated in the Tools -> Options... you need to click the Update button.


You can take advantage of the Related Objects viewer to focus on an object and see how it was constructed via its related objects. The related objects command identifies the parent, any children or connected objects and the relationship between objects.

Getting Information from the Specification Tree IconsEach time you click the Apply or OK button during the definition phase, or if you update the bundle segment after any parameter modification, the following algorithm is launched to compute the best possible shape. Depending on the result, the specification tree is updated according to the following chart:

Note that working in Cache mode, the bundle segment does not display the icon.


Routing the Bundle SegmentUsing an Heterogeneous Context

This functionality allows you to route bundle segments (branchable or normal ones) on surfaces.It is possible to route a bundle segment onto different surfaces preserving the bundle segment's bend radius definition.

● Since you are routing the bundle segment on a surface, the associativity is not maintained.

● The Bundle segment on surface option is not available with this function.But you can change the side on which the bundle segment will be created on the surface using the Shift key.

● It is possible to add or remove construction points or tangents instantly using the corresponding buttons. See Detailing the options.

● This command also works in visualization mode so you do not need to load the context in design mode.

Open a new product document.Select the Insert -> Existing Component... item, and choose the FreeEdges1.CATPart document.The path to this sample is: .../online/cfysa_C2/samples/FreeEdges1.CATPart.


1. Change the Product1 document into a geometrical bundle using the corresponding button .

2. Click the Branchable Bundle Segment button .

The Electrical Harness Assembly workbench switches to the Electrical Harness Installation workbench.The Bundle Segment Definition dialog box opens.Enter the value of your choice for the different parameters.



4. Pressing the Ctrl key displays a manipulator as well as the tangent representation.

This manipulator follows the surface when you move its position.It shows a point pre-positioned perpendicularly to the surface, with a distance to this surface equal to:

❍ the bundle segment radius in Automatic mode,

❍ the specified value in Manual mode,

❍ the bundle segment radius increased with the safety margin value in Automatic with safety margin.


a. Click successively where you want to define the flexible curve.

b. Releasing the Ctrl key ends the flexible curve definition.


5. You can modify the route by adding, replacing or removing points as well as modifying the tangent

direction.


The Bundle Segment Route Definition dialog box closes.

The Bundle Segment Definition dialog box is displayed afresh.




8. Optional - Clicking the More >> button lets you access to specific options:

The Offset management at creation.

The default value is set to Automatic offset: the flexible curve follows the surface with an offset equal to the bend radius value.You can change to Manual offset if you want to define the route at a selected point with a different offset. For example:

a. You have started to draw the curve with the automatic offset, using the Ctrl key.

You want to change the route.So release the Ctrl key and get access to the Bundle Segment Route Definition dialog box.

b. Click the Manual option and change the value if necessary.

c. Press the Ctrl key again to follow the route definition.

Note: You can change the mode for only one point or more.If you come back then to the automatic offset, the result will look like this:


Release the Ctrl key to end the route definition.

d. Click OK to validate the route definition.



In Automatic mode, the bundle segment will keep in contact with the surface when the bundle segment is modified.The bundle segment will not keep in contact with the surface if the surface is modified.


Routing the Bundle Segment Following a Part

The FollowOnPart.CATProduct document is open. The construction constraints have been defined.The Bundle Segment Definition dialog box is still open from the previous task.

● The bundle segment route is associated to the part.As a consequence, if the part is modified, the bundle segment is updated.

● It is possible to add, remove or modify construction points or tangents instantly using the corresponding buttons.

● When you create a bundle segment on a part, ❍ the Bundle Segment on Surface option is activated and lets you change the side on which the bundle

segment will be created.To do so, click the Reverse button.

❍ the Bend radius and the Build mode parameters (Mode, Slack % and Length) are not taken into account.

❍ the local slack management is not taken into account either. This command is disabled.

You cannot route branchable bundle segments on part using this scenario. Refer to the other method.



2. Click successively Point.1, Point.2, Point.3 to define the flexible curve.

3. Check the Geometry on support box, and select the face on which the points have been defined

(Surface.1).



The Bundle Segment Route Definition dialog box closes.

The Bundle Segment Definition dialog box is displayed afresh.

Note: At that time, you can use the Reverse button to create the bundle segment on the other side of the

surface.



Note: Two extra points have been created: they are the bundle segment extremities (Point.6 and Point.7).


Routing the Bundle Segmenton an Existing Helix

Open the HelixBundleSegment.CATProduct.

1. Select the helix in the geometry or the specification tree.

2. Click the Bundle Segment button .

The bundle segment is added to the specification tree: the Flexible Curve is created.


CATIA switches to the Electrical Harness Installation workbench (Part).

3. Click the Bundle Segment Definition button .

The Bundle Segment Definition dialog box opens: you can only change the name, diameter or section.




● The bundle segment route is associated to the part. As a consequence, if the part is modified, the bundle segment is updated.

● This functionality also works on line, curve, spline and spiral.


Sharp Bending Bundle Segment...

You are routing a bundle segment and the construction constraints lead to a sharp bending bundle segment.

When the bundle segment creation is impossible because it would induce a violation of the minimum bend radius rule, a message warns you that a computation error occurred, showing the construction constraints causing the error.

Nevertheless if you validate the bundle segment creation using these construction constraints, the Flexible Curve icon is modified in the specification tree to show that it is invalid:

You can then modify the bundle segment parameters or the construction constraints.


Creating all the Bundle Segmentsin a Single CATPart

This task explains how to create all the bundle segments of a geometrical bundle in a single CATPart.A dedicated option allows the user to choose this working method.However to take advantage of ENOVIA configuration management, this option needs to be unchecked if you want to manage the effectivity at a more detailed granularity level: the branchable bundle segment.

This new object is named multi-branchable bundle segment.

When created, you can edit a multi-branchable bundle segment or one of its components.

The multi-branchable bundle segment is a new data modeling.It aims at creating the harness in a single part, reducing the size of the documents, the number of contextual links and consequently the update time. Moreover, as all the branchable bundle segments are created in a single document, deleting one does not require deleting any document in the file system or in ENOVIA data base.

The tree structure is the following:

Editing and modifying a branchable bundle segment created in the previous release versions, convert it into a multi-branchable bundle segment.

At creation, the multi-branchable bundle segment contains the one part with only one branch (Branchable1) and one bundle segment (bundle segment1).

The geometry will be created under this part in the different bodies.

The branchable bundle segment is a set of bundle segments that share the same centerline.

The bundle segment belongs to the part document and has electrical properties.

According to the dedicated option value and to the selected object, you will create or edit a multi-branchable, a branchable or a bundle segment:


● if the dedicated option is checked (or not) and no multi-branchable exists, the command creates a new document (Multi-Branchable1).

● if the dedicated option is checked and one multi-branchable exists, the command edits the document and no new document will be created.

● if the dedicated option is not checked and the geometrical bundle is activated, the command creates a new document (Multi-Branchable n).

● if the dedicated option is checked (or not), at least one multi-branchable exists with a branchable already defined, and if nothing is selected in the geometry, the command creates a new branchable (Branchable n).

● if the dedicated option is checked (or not), at least one multi-branchable exists with a branchable but no route has been defined, and if nothing is selected in the geometry, the command edits the branchable (Branchable1).

Dedicated commands have been created to add and remove branch points although it is still possible to access them through the Segment Definition dialog box.

Creating a New Multi-Branchable Bundle SegmentOpen the Multi-Branchable document: it contains a geometrical bundle and two connectors.

Check the Bundle Segment Creation dedicated option is enabled, that is to say Work with one multi-branchable per geometrical bundle is checked.

1. Double-click to activate the desired product: GeometricalBundle1

2. Click the Multi-Branchable button .

The Electrical Harness Assembly workbench switches to the Electrical Harness Installation workbench.The Bundle Segment Definition dialog box opens:

The bundle segment document Multi-Branchable is created including, by default:


❍ the Part document that becomes active: Multi-Branchable

❍ the Flexible Curve - created in the ElecRouteBody - belonging to the part, which, at that time, does not have any geometrical representation

❍ the Branchable1 with the Bundle Segment1, which, at that time, does not have any geometrical representation.

If the multi-branchable bundle segment has several bundle segments, the diameter field will be grayed out. Use the Segment Definition button to manage the individual diameter.

3. Enter a value in the Diameter field. The Section is automatically computed.

As an alternative, you can enter the Section, the Diameter will be computed.

A message warns you that the bend radius must be at least equal to the Diameter value to insure the correct bundle segment route computation.

The bundle segment, here Bundle Segment 2, has been created as well as the branch point, here Point.3.

The Extremity Management becomes available where you can modify the coordinates.The Visualization Management allows you to reframe the geometry on the selection.

As a branch point has been added, the branchable bundle segment consists of two sub-segments that can have different parameters. Those sub-segments share the same centerline and are stored into the same CATPart document.The branch point is not fixed as a bundle segment definition point but placed directly on the centerline. Thus, when modifying the centerline, the branch point will follow the curve.


Removing a Branch Point

3D Harness TolerancingUsing FTA

This task makes use of the Electrical Harness workbench integration together with the 3D Tolerancing and Annotation

product. It lets you easily define and manage 3D tolerance specifications and annotations directly on the 3D or

flattened harnesses.

This allows the user to add dimension information directly to the 3D mock-up so that they are available for

downstream process. For example, the contents of the 3D session can be sent to a harness supplier for

manufacturing purpose and the dimensions to be respected will be part of the data provided.

This function makes it possible to annotate:

● the distance between two connectors of a geometrical bundle through multiple bundle segments

● the distance between two supports

● the distance between a connector and a protection

● the distance between a branch point and a connector

● etc.

A Product Functional Tolerancing & Annotation license must be available to perform this scenario.Refer to the 3D Functional Tolerancing & Annotation User's Guide for more information on the product.

You can use the following sample: ...\online\cfysa_C2\samples\ElectricalAssembly\ElectricalAssembly.CATProduct

1. Switch to the Product Functional Tolerancing & Annotation workbench.

2. Select the Projection View/Annotation Plane button.

Select a plane or an axis system to define the annotation plane.

Here the horizontal plane for example.

The Projected View is added to the specification tree.

Note that all planes that contain the extremities of the curve to be annotated will be suitable for the curvilinear length dimension display, as it will be used to project the annotation on.Else, to get a better presentation, the viewpoint should be set perpendicular to this annotation plane.

To do so, click the Normal View button and select the annotation plane of interest.

3. Select the Curvilinear Dimensions button in the Dimensions toolbar.

You are prompted to select the first element for the dimension creation.


❍ In the context of the Electrical Harness product, you can select a plane, a point or a spline.

❍ Whatever the number of elements, at least one spline must be selected.

❍ They must be ordered from one end to the other.

❍ They must be in an electrical part (connector, equipment, bundle segment, support, back shell,

protection, etc.)

❍ The electrical continuity between the different elements selected is mandatory.

For more information about this command, refer to 3D Functional Tolerancing & Annotation User's Guide - Basic Tasks - Creating Annotations - Creating Curvilinear Dimensions.

4. Select for example: a connector face, two splines and a support face to delimit the second spline.

❍ the connector face:

❍ the first spline:


Note that at that time:■ the new feature appears in the specification tree (xxx.Part for Constructed Geometry)

■ the dimension is previewed. By default, the dimension line is linear.

You can switch to other visualization modes:■ Right-click the dimension line to display the contextual menu.

■ Select Parallel.

Refer to 3D Functional Tolerancing & Annotation User's Guide - Basic Tasks - Creating Annotations - Creating Curvilinear Dimensions to see the different view option.

Optionally, you can drag the dimension line and/or the dimension value to position them as wanted.

❍ the second spline:


The dimension line is updated.

❍ the support face to delimit the second spline:

5. Click in the free space to validate and end the dimension creation.

The dimension appears in white.


The semi-arc symbol displayed over the dimension value symbolizes a curvilinear length dimension. You can now handle the dimension just like any other dimension.

User Interface Behavior


Selection of a 3D curve:

If the user selects a 3D curve of a branchable bundle segment, then the curvilinear length dimension will be displayed in the geometry and the user will have to click in the free space to validate the dimension creation and to exit the command (no other geometric selection will be proposed).

Selection of the first 3D curve after the selection of a starting point or planar face:

If the user selects a point or a planar face, he will then be prompted to select a harness routing spline.

Selection of others 3D curves:

Then the user will be prompted to complete the selection of harness routing curves or to select the ending point or planar face of the curvilinear length:If the user selects another curve, the software will check the consistency between the curves. If the last selected and the new selected curves are not connected, an error message will be displayed and the last selection will be removed. The user will again be prompted to complete the selection of harness routing curves or to select the ending point or planar face of the curvilinear length.

Selection of an ending point or planar face:

If the user selects a point or a planar face, the curvilinear length dimension will be displayed in the 3D and the user will have to click in the free space to validate the dimension creation and to exit the command (no other geometric selection will be proposed).

Associativity

If an object taking part to the curvilinear dimension is moved in the 3D geometry, the annotation is updated.

Electrical continuity

It is not possible to create a curvilinear dimension for bundle segments belonging to different geometrical bundles.

If you select points or planes, CATIA will find the best solution to compute the length the user intends to annotate:

● Selection of a point:

❍ On the bundle segment centerline: this point will be used as an extremity of the annotated length.

❍ On a support: the projection of the point on the bundle centerline will be used as an extremity of the annotated length.

❍ On a connector: a straight line will be added to this point from the bundle centerline extremity.

● Selection of a plane:

❍ On a support: the intersection point between the plane and the centerline will be used as an extremity of the annotated length. If the selected plane does not intersect with the centerline, the plane is ignored.

❍ On a connector: a perpendicular line between the bundle centerline extremity and the plane will be added.


Creating Adaptative Part

This task explains how to define an adaptative part such as a support, using a formula.

Open the AdaptativeClamp.CATPart document.

This document also contains three formulas that have been defined to re-compute the support geometry after routing:

1 - The support remaining length value is set to:20mm*(2*PI+1)-(2*PI*ELEC-SUPPORT-RADIUS)

2 - The inner diameter value is set to:ELEC-SUPPORT-RADIUS

3 - The outer diameter value is set to:ELEC-SUPPORT-RADIUS + 2mm


1. Click the Formula Editor button .

2. Select the Length type and click the New parameter of type button.

3. Enter the name for it: ELEC-SUPPORT-RADIUSand a value: 18mm for example

Note: the name must strictly be ELEC-SUPPORT-RADIUS.

4. Select the support radius (PartBody\Sketch.1\Radius.50\Radius) and click the Add Formula button:

5. Enter the formula:

PartBody\Sketch.1\Radius.50\Radius = 'ELEC-SUPPORT-RADIUS'

(the radius is equal to the new parameter ELEC-SUPPORT-RADIUS)


6. Click OK to validate the entries made in both dialog boxes.

Now, if you route a bundle segment through this support:

● A formula will automatically be generated under the root product of the document, if and only if the ELEC-SUPPORT-RADIUS parameter has been detected:

Support radius = Bundle segment diameter * 0.5

● The support will exactly fit the bundle segment diameter. The formulas given above are used to re-compute the support geometry.



Using the Mechanical Assembly Integration

This task makes use of the Electrical Harness workbench integration together with the mechanical modeler. It demonstrates the associativity between the bundle segment and the part.

The document contains a bundle segment routed on a part.

1. Modify the sketch of the pad.

The bundle segment is no longer leaning on the face of the pad.

2. Close the Sketcher.



3. Double-click the bundle segment in the specification tree.

The document is updated:


V4/V5 Electrical Data Migration

This task explains how an existing CATIA V4 Electrical model is converted into V5 documents.The conversion of the V4 data is performed using the migration batch.By default, the batch will only migrate the geometry of the BNSs and BSJs.

To perform the migration of electrical data, you'll need to set up a migration utility parameter.

This option can also be defined using the Tools -> Options... -> General -> Electrical tab together with the Batch Migration tab.Refer to the Infrastructure User's Guide (Customizing Settings - General - Compatibility).

To know more about V5 devices, refer to Electrical Library User's Guide.

The V4 MASTER workspace becomes the main V5 CATProduct document while:

● each geometrical SET becomes a CATPart,

● each DETAIL workspace becomes a CATPart,

● each GBN becomes a CATProduct,

● according to the selected option:

❍ each BNS becomes a CATPart, if Bundle segments is chosen

❍ all the BNSs of a GBN are stored in the same CATPart, if Multi-branchable bundle segments is chosen.

The CATPart documents resulting of DETAIL workspaces are instantiated as many times as there are DITTOS in the main document.

The root document is a CATProduct named: <V4 Model Name>.CATProduct.

Even though the electrical applications use catalogs, the migration batch migrates only the components in the models, not in the libraries.

Interoperability with ENOVIA LCA

In the context of ENOVIA LCA, you must first uncheck the Use root context in assembly option, which is located in the Part Infrastructure -> General -> External References frame. If not, the links will be created to the root of the assembly and it will not be possible to save the geometrical bundle in ENOVIA:

By default, this option is checked.


Now let us see an example:

In this V4 model, the SIC comes from a V4 library: each SIC instance (DITTO) has the same reference (DETAIL).In V5, the same structure is recreated: each connector is an instance of the CATPart.

The migration applies to V4 BNSs (circular section only).The BSJs become connections between bundles segments.The electrical behavior is added to the geometry of the converted equipments, the connector shells and the single insert connectors.The bundle segments are now connected to the devices (single insert connector or connector shell) and tangency is maintained.The local slack is maintained.The supports (SPT) are converted into mechanical parts to which the bundle segments are linked through publications.The bundle surface (BSF) becomes a protection of tape type.The terminal block (TB) and the terminal strip (TS) are not migrated. Only the geometry appears with no electrical behavior.The external splice (ES) is migrated as a connector of external splice type.The internal splice (IS) is migrated as a connector of internal splice type.The geometry of the bundle junction (BSJ) is migrated as is.

The V5 documents created by migration of V4 electrical models are named as follows:

<Name of the model>_<CATIA V4 Detail Identifier>for example: TEST_MODEL1_ECP1.CATPart

When migrating several models at a time, if they contain the same device, a CATPart will be generated for each V5 document (i.e. two models using the same SIC will migrate as two V5 documents with two CATPart documents).

Known restrictions:● There are no mechanical links (permanent restriction) between the single insert connectors (CPP and Clocking not

supported).

● For the time being, when migrating multi-section supports, only the first created section keeps link with the bundle segments. For the other sections of the support, the bundle segments are not linked to the support.

● For the time being, the result of the V4 to V5 migration is stored in Workpackage in ENOVIA. The Explode mode is not available.


Permanent restrictions:● If the V4 BNS bend radius is smaller than the V4 BNS diameter, the bend radius value taken into account will be equal to

the diameter.

● The rectangular section BNS is migrated as a circular section bundle segment.

● The V4 BNS created in BEND mode ends in a slightly different shape:

The V4 BNS is shown in yellow, the corresponding V5 bundle segment is shown in red.

To perform the migration of electrical data, you need to set up the following parameter:

1. Open the Tools -> Utility... menu item:

This tab lets you define if you want your V4 BNSs migrated as bundle segments or multi-branchable bundle segments.

Bundle segments is the default value.

7. Select the option of interest and click OK to validate.

You can now migrate your V4 data according to your choice.

An alternative is to launch the Migration batch as follows:

1. Enter the following command: CNEXT -batch -e CATV4ToV5Migration.

2. Select a target directory (where the V5 documents will be created).

3. Select the V4 documents to be converted.

4. Click the Migrate button.


The Options... button lets you define if you want your V4 BNSs migrated as bundle segments or multi-branchable bundle segments. Bundle segments is the default value.

Electrical Integration from Functional Data

This scenario puts together the functionalities from the four workbenches used successively to create an electrical product. As an example: a hair dryer.

It can be split in four phases:

the electrical system definition using Electrical System Functional Definition

the device implantation in 3D environment with Electrical Library

the physical harness creation using Electrical Harness Installation

and finally the electrical wire routing with Electrical Wire Routing.

Re-using predefined electrical systems to create a more elaborate system

❍ PowerSupply

❍ HairDryer

❍ HairDryer_Signals

4. Map the functional connectors to the physical ones using the contextual menu:

(connector_M: extension cable connectors to be plugged onto the batteries)

This action makes it possible to predefine for each functional connector what device reference to be used for the 3D

placement. This will simplify the 3D Designer work: he's driven by the functional data, reusing the Electrical System

engineer knowledge to achieve the 3D implantation.

5. Connect terminations and signals using the Assign icon .


This action makes it possible to define the signal extremities corresponding to the power supply and the hair dryer

systems.

6. Save the electrical system assembly using this icon .

The electrical functional system is defined.

It is saved in the HairDryer_Assembly.CATProduct document in the samples folder.

7. Launch a CATIA session.

❍ The bundle segments diameter are updated according to the signal section.

❍ The specification tree is updated.

6. Multi-select Signal_plus and Signal_minus using the Signal icon .

7. Click the Automatic Routing icon .

❍ The specification tree is updated: the wires and wire connections are created.

❍ The length of the wire linked to a back shell is extended with an extra-length, defined as a back shell attribute.However, an alternative is to connect the bundle segment through the back shell: in this case, the wire length is equal to the total length of the bundle segments of the wire route.

❍ The bundle segments diameter is updated using the section defined on the signals (with EFD).

❍ When only one signal is selected, the wire connections are displayed (as shown below).



Editing Electrical PropertiesHere is an example of a document demonstrating how electrical properties on component are managed within CATIA Electrical products.And moreover, new properties have been added to a number of electrical components:

functional equipments and connectors defined in EFD

electrical bundle defined in EWR

bundle segment defined in EHI

A CATProduct document may contain references or instances of the components.Let's see the differences on the following documents:

● The Equipment.CATProduct contains an equipment.It is the reference of the component.

● The RootProduct.CATProduct contains an occurrence of the equipment (Insert -> Existing Component...).The Equipment(Equipment.1) is an instance of the component.

Depending on the component you have activated (by double-clicking: blue object) and on the object you have selected, the properties you will edit may be the ones of the reference or of the instance.


1. In the Equipment.CATProduct, if you edit the properties of the Equipment, you will display the

properties of the reference.

Type and External Reference are attributes of the reference.

If you modify them, all the occurrences will be modified.

2. In the RootProduct.CATProduct, if the RootProduct is active (in blue in the specification tree) and if

you select the Equipment.1 to edit the properties, you will display the properties of the instance:

The instance also has instance attributes: Reference Designator and SubType.


If you modify the attributes of instance, only this instance will be modified.On the other hand, if you modify the attributes of reference, they will be modified in all the occurrences and in the reference document.

3. In the RootProduct.CATProduct, if the Equipment.1 is active (double-click Equipment.1) and you

select the Equipment.1 to edit the properties, you will display the properties of the reference:

If you modify the attributes, the reference will be modified:❍ Equipment.CATProduct will be modified

❍ and all the occurrences of the component.


Notes:

● This behavior is specific to the electrical properties.

● When a product is activated (by double-clicking), editing the electrical properties operates in the same way as if the electrical properties were edited in the document in which the root product is the reference of the active product. (i.e. Equipment.1 in the RootProduct document against Equipment in the Equipment document.)This definition is recursive within all the levels of instance.

Functional equipments and connectors propertiesWhen you edit the properties of a functional equipment or connector, the Preselected Physical Device frame indicates if a physical component corresponding to the functional one has been chosen to be placed in the geometry. Two fields give this information:

● Catalog Path indicates the location of the catalog containing the physical component

● Part Number indicates the part number of the physical component.


Electrical bundle propertiesWhen you edit the properties of an electrical bundle, the Associated Geometrical Bundle frame indicates in a list the name of the geometrical bundles being part of the electrical bundle.


Bundle segment propertiesWhen you edit the properties of a group of bundle segments, the Length in out field indicates the total length of the bundle segments selected.



Viewing Related Objects

This task shows how to use the Related Objects viewer to navigate through the objects connected to the selected object.

You can focus on an object and see how it was constructed via its related objects.The related objects command identifies the parent, any children or connected objects and the relationship between objects. It is available when none of the icons of the workbench are activated that is to say when you are

in Select command . Accessing related objects can be done in two ways:

● by clicking the Related Objects icon in the toolbar

● from the contextual menu, by selecting Related Objects.


The different options available are:

Reframe on selection: reframes the main 3D window on the Related objects selection.

Reframe on selection: the main window selection corresponds to the Related objects selection. The main window display is not reframed.

Freeze: freezes the contents of the Related objects window. You can still navigate in the main window: the Related objects view will not be updated.

Freeze: the Related objects selection corresponds to the main window selection.

View related objects: displays the parent, any children or connected objects.

View related objects: only displays the selected objects.

Functional: displays the functional system. If the bundle segment contains wires, the corresponding signals are displayed in the bundle segment.N.B.: the signal name is displayed followed by the separation code, if

any:

Functional: hides the functional children elements.

Wire: displays the wires contained in the bundle segment.

Wire: hides the wires contained in the bundle segment, shows the bundle segments and signals.

Harness: displays the relationship to the harness: connectors, equipments, shells, etc.


Harness: hides the children bundle segments, only shows the signals and wires.

Sub objects: displays the electrical contents.

Sub objects: hides the electrical contents.

On a complex electrical system, the 3D view allows you to limit display to a specific area thus enlightening the information regarding this area.

mode, according to the objects considered.

We recommend that you read the VPM Navigator User's Guide to know more about this product.

This documentation can be found on the ENOVIA LifeCycle Applications Documentation CDRom.

Working with Geometrical Bundle as Workpackage

A workpackage is a set of documents that are stored in ENOVIA LCA as a single entity.

This means that a node in CATIA specification tree is chosen as an entity to be shown in ENOVIA LCA. The children are

not visible as documents in ENOVIA LCA.

The geometrical bundle is a candidate to be stored this way, as it represents a complete and coherent package for the

electrical design.

Within CATIA connected to ENOVIA LCA through VPM Navigator, if the user selects a new product as a geometrical

bundle, the system automatically knows that this geometrical bundle has to be stored as a workpackage.

Checks are performed when using the Electrical tools to ensure that all entities created or modified will be correctly

stored, using the following rules:


● No links to geometry (that is to say external references) can be done from the part inside a workpackage to a part

outside the workpackage.

● The context for the external links must be set to a product node inside the workpackage.

Refer to Infrastructure User's Guide - Customizing Part Infrastructure.

● Mechanical constraints and electrical connections between parts inside the workpackage and outside the workpackage

must rely on published objects.

To make this possible, the following settings must be applied when working with CATIA connected to ENOVIA LCA, to

store the geometrical bundles as workpackage in ENOVIA LCA:

a. Select Tools -> Options -> Infrastructure -> Part Infrastructure -> General tab.

In the External References frame, uncheck Use root context in assembly.

b. Select Tools -> Options -> Equipment and Systems -> Electrical Harness Installation -> Harness

Management tab.

In the Contextual Links frame, for Keep link with selected object, choose In geometrical bundle in the

list.

Anyway, the system checks that the rules are not violated and if those options are not set properly, an error message is

displayed:


Moreover, during the electrical connection between devices and/or bundle segments that are not inside the same

workpackage, publications are automatically created on the geometrical bundle stored as workpackage, to ensure that

constraints and connections are correctly stored.

Working with Geometrical Bundle in Explode Mode

Using the Explode mode, all the nodes of the product structure are stored in ENOVIA LCA.

This means that each component and its children are as many documents visible in ENOVIA LCA.

Within CATIA connected to ENOVIA LCA through to VPM Navigator, if the user selects a new component as a geometrical

bundle, the system automatically knows that this geometrical bundle has to be stored in explode mode.

A single check is performed when using the Electrical tools to ensure that all the entities created or modified will be

correctly stored:

The context for the external links must be set to the root product node of the session.

Refer to Infrastructure User's Guide - Customizing Part Infrastructure.

To make this possible, the following settings must be applied when working with CATIA connected to ENOVIA LCA, to

store the geometrical bundles in explode mode in ENOVIA LCA:


a. Select Tools -> Options -> Infrastructure -> Part Infrastructure -> General tab.

In the External References frame, check Use root context in assembly.

Electrical Harness Installation This page deals with the options concerning:

● the bundle segment creation

● the bundle segment naming rule

● the bundle segment connection

● the bundle segment disconnection

● the management of contextual links.

Click here to see the parent page.

Bundle Segment Creation

Geometrical bundle is mandatory

If this option is checked, it means that you need to create a geometrical bundle prior to defining a bundle segment.


Work with one multi-branchable per geometrical bundle

If this option is checked, only one multi-branchable bundle segment can be created within a geometrical bundle: a

single part contains the full harness, reducing the size of the document, the number of contextual links and

consequently the update time.

However to take advantage of the ENOVIA configuration management, this option needs to be unchecked if you

want to manage the effectivity at a more detailed granularity level: the branchable bundle segment.

Check this option if the configuration management does not need to be done at the level of each branchable bundle

segment, but at the level of a set of branchable bundle segments created in a single document.

By default, this option is unchecked.


Bundle segment color

Use the color chooser to define the bundle segment color at creation.

Bundle Segment Naming Rule

Bundle segment (#PN#)

If this option is selected, the bundle segment name shows like this in the specification tree:

It is the default value.

Parent-bundle segment (#PN#)

If this option is selected, the bundle segment name shows like this in the specification tree:

Bundle Segment Connection

Geometrical link

If this option is checked, when the selection is completed, the bundle segment is extended to the second point

selected (which is either a bundle segment extremity or a bundle connection point).



Automatic link to new bundle segment

If this option is checked, the electrical connection is created at the same time as the bundle segment.


Bundle Segment Disconnection

Remove geometrical link at unlink

If this option is checked, when a bundle segment is disconnected from a connector, the geometrical link is also

removed and the bundle segment geometry is modified to its last but one definition point.


Contextual Links

For this option to be taken into account, you must first uncheck the Use root context in assembly option,

which is located in the Part Infrastructure -> General -> External References frame. If not, the links

will be created to the root of the assembly.


Keep link with selected object


The object created from the selection will or not keep the link according to this option. This option can take three

values:

● Always: always creates the external reference links.

It is the default value.

● In geometrical bundle: creates external reference links only if the selected object is part of the geometrical

bundle of the bundle segment.

● Never: always creates a local copy of the selected object with no associativity.

Forbid selection outside current geometrical bundle

If this option checked, the selection of points, supports or devices which do not belong to the current geometrical

bundle for bundle segment routing is forbidden.

Click here to know all the details about the Compatibility -> Electrical options.


Bundle segments

If this option is checked, each V4 BNS is migrated to a V5 bundle segment (CATPart document).


Multi-branchable bundle segments

If this option is checked, all the BNSs of a V4 GBN are migrated to one multi-branchable bundle segment in a

V5 geometrical bundle. All the V5 bundle segments are stored in a single CATPart document, the multi-

branchable bundle segment CATPart.
