Modify assembly without changing all linked components.

I'm designing a wooden shipping crate and I have an assembly that's made up of a piece of plywood and 3 identical 1x4 boards. Once assembled, I need to drill 2 holes in the center 1x4 through the plywood to mount a bracket. When I go to the assembly level and extrude holes they are copied to all of the 1x4s, not just the center 1x4. I know that I can create a separate unlinked part that has holes drilled, but then that messes up my BOM/parts list. Any insight would be appreciated.

If you extrude a hole in a component then it will appear in all instances of that component. Copy the component, extrude the hole in that and replace the ones that need to have the hole.

Correct me if I'm wrong, but doesn't that make the component with holes a different PN than the components without holes? Ideally I keep the same PN for BOM/structure purposes.

Then you need a dirty work around 🙂 draw both as bodies inside the same component and then hide the body you don´t need at the assembly level.

I didn´t test this, so I´m not 100% sure it will work.

Great Post!!!!

I was having the exact same issue with an internal component. I exported the component and edited it by creating copied bodies and included the features I desired. I then replaced the internal components with the new external component, and just hid the bodies as required for each instance.

Worked great! Thanks so much!!!

That certainly works, but you don't actually have to export (save copy as) those components.

You can simply:

1. use the boundary fill feature to create a 2nd body

2. then remove (not delete) the 1st body

3. refine the 2nd body

Edit: Scratch the above.

Export the component and then use Derive.

I'll give this a try. Thanks!
