copy object not updating when parent changes

[Anonymous]

Hi There,

I have two parts in an assembly, (A&B)

In Part A have two solid bodies A1 and A2.

A1 describes the part A2 describes a solid which is used to Boolean holes and pockets into Part B

Once the two parts are mated together I edit B and copy the Boolean A2 solid into B using copy Object then use combine to cut the Boolean solid from the base solid.

All works well but the idea is when I change Parts A, and hence A2 I want the copy object to also update and move the corresponding Boolean operations. It seems that once copied the A2 solids are not associated to the original A2 solids even though that have a green tick next to them in the feature tree. 

Am I using this feature incorrectly? IS there a better way of doing this? alternatively if this is a valid work process how should I fix the issue?

Thanks for your help

Hi Ben

When you use the Copy Object function are you copying as a solid or a composite surface? I suspect you are using solid in which case the associativity is broken. Choose the composite surface option and make sure Associative is selected. Then use the Sculpt tool to remove the composite surface from your solid body. When you are finished editing part B it should be marked in the browser as being adaptive; red and blue circular arrows next to the browser part icon.

As an alternative you could possible derive part A into B as long as the origins match. You could also create a block of the shared features in part A and derive that into B, place the block into a new sketch and extrude as normal.

Hope that helps.

Hi! Please share the example here so forum experts can take a look. It could be the way it works like Mike mentioned here or it could be a bug.

Many thanks!
