Dear 3DExperience and CATIA Fans,
A lot of my customers asked me “how can we transform a product to a part like in CATIA V5?” and the answer → Derived Representation feature in CATIA Assembly Design.
In this article you will learn how to transform an assembly into a part using the derived representation feature.
Here a the following steps you need to execute for this tutorial.
Step 1: Assembly Preparation
Open an assembly containing few parts. In that case, it is a small assembly composed of 8 parts (Pulley, Axle, Bearings, etc.). It is a simple example for you to start to be familiar with the scenario.
Right click on the Root Product and insert a 3DShape.
This one is fixed in the assembly, and will be used for the derived representation. (Basically the whole product will be transform into a part inside the 3DShape.
Step 2: Use Derived Representation
Use the feature derived representation on the assembly
Select the 3DShape that you just created.
Tick the option “keep link” in the panel.
Then select the parts you want to keep and the one you want to remove from selection
Click on OK
The assembly is hidden, and now the geometry are inside the 3Dshape (the parts become bodies)
Step 3: Boolean operations
Now you have several bodies.
-> Go to structure tab in action bar
Use the feature Add
Add the different bodies to the PARTBODY (repeat action several times)
Then create a new Body
Call it “CUT”
Draw a sketch and extrude a profile
Use the feature Remove
And remove the CUT to the PARTBODY
Now you have a cut in your 3DShape
Step 4: Drawing (optional)
Insert a Drawing in the root assembly
go to Drafting application
Insert an isometric view
go back to assembly
select the 3DShape
The view is now generated
Watch and Learn 🙂
In the video you can see how to transform a small assembly to a part and make a cut. You can keep the links with original parts and change parameters.
