Cut structural foundation with nested family

[aleksei.tkachenko]

Hello

I have a following problem with structural foundation family

I created concrete pile cap as structural foundation family and added pile as nested structural foundation family. And I’m unable to cut pile from pile cap. How can I do it?

When I insert my family into projcet I get result as shown on the picture

I think you want it to look like the image below.

If so, you will need to create voids in the foundation to show where the pile cap is embedded.
