Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge
WIRING HARNESS DESIGN IN CATIA V5 WEEK 5 AND 6 CHALLENGE
The electrical connectors are represented by numbers in the above figure. There are 8 different types of connectors at 10 different locations.
--Bundle continuity has to be checked for the two created harnesses.
--After the two Harnesses are created, the next objective is to have them interconnected electrically.
--Check for bundle warnings in Harness A and Harness B.
--Add annotations to all the connectors in Harness A and Harness B.
--Define all the electrical connectors geometrically and electrically so that they can be used in the wiring harness.

HARNESS A
After all the connectors are defined, the workbench was switched to Electrical Harness Assembly where Geometrical Bundle was activated. All the
connectors were routed using the Multi-Branchable Document command.
HARNESS B
After all the connectors are defined, the workbench was switched to Electrical Harness Assembly where Geometrical Bundle was activated. All the
connectors were routed using the Multi-Branchable Document command.
CHECKING CONNECTED OR NOT
--Now in this step, we have to check bundle continuity in both Harness A and Harness B.
--So for that, go in Edit>Search>Workbench-Electrical>Type-Bundle segment>Attribute-fully connected.
--We will get one window, in that selecting True option will show all the connected bundle segments while selecting False option will show all the
non-connected bundle segments.
--Now, we will check for True condition and search for result.
--All the bundle segments are showing connected. So there is bundle continuity in both Harness A & Harness B as shown in below images.
ASSEMBLY OF HARNESS A AND B
--In this step, we have to interconnect both Harness A & Harness B.
--For that, we have to create new product file and can give name as Assembly.
--Then, copy both harnesses and paste it in newly created product file or call both harnesses in mechanical assembly design as below image.
--We have to go in Electrical Assembly Design to connect both the harnesses electrically. So for that, select the option 'connect electrical devices'
and both the harnesses will get connected electrically as below.
--As shown in below image, male connector should have to be inserted into the female connector.
ANNOTATIONS
--In this step, we have to add annotations for all the connectors in mechanical assembly design workbench.
--Annotations are used for giving connector name, functions etc.
--For this, we have to select plane where annotation will be placed. In below image, we have selected front plane.
--We should make sure that the geometrical bundle is active before selecting the annotation plane.
--We can change a font, font color and font size by going into the properties as shown in below image.
CONVERTING TO CAT PART
--Now, in this step we have to convert final harness assembly file into IGS format. So for that we need to follow below steps.
--Mechanical Assembly Design workbench>Tools>Generate CAT Part from product.
--Once the CAT part is created, the whole product file is converted into a single part.
--Now, whole file is converted into the IGS format and we can see all the harness assembly is looking in grey color.
--If we need to change color as before in green, we can go back and give green color to each bundle segment.
CONCLUSION
--Bundle continuity has to be checked for the two created harnesses.
--After the two Harnesses are created, the next objective is to have them interconnected electrically.
--Check for bundle warnings in Harness A and Harness B.
--Add annotations to all the connectors in Harness A and Harness B.
--Define all the electrical connectors geometrically and electrically so that they can be used in the wiring harness.THIS PROCESS IS DONE
