Hole function on an assembly (remachining of a welded assembly) instance problem

3D Design Assembly

Hello
I want to make holes on an assembly but when I use the assembly hole function, the holes also put on the other instances (parts of the same reference) present in my assembly but I would like these holes to be only on the parts I want.

Example below
I have a frame assembled of welded parts together and I want to make my holes (in yellow) only on two pieces

I used the assembly functions in solidworks but I can't get the same type of result in Catia...

Hello Vadim,

I had the same inconvenience when switching from Inventor to Catia.
Catia does the update and all the parts of the assembly that have the same reference are modified.
I found no other solution than to copy the parts, rename them, make the holes and replace them in the assembly :frowning:

Have a nice day.
