# 3d Modelling of a new solid out of a moving assembly in Solidworks

## 3d Modelling of a new solid out of a moving assembly in Solidworks

(OP)
Hello guys, and thank you for accepting me to your forum!

I have the following question, which is nowhere to be found. Is it possible to derive a new solid/or even a net/ body out of an moving assembly, so the new body will then serve as a no-go space constraint for the parts to come after that in that assembly?

Imagine a recumbent bike with a pedalling puppet in a recumbing position, it is all well connected to the pedals and made movable, now I want to model the outer hull of the bike around his feet, as thight as it could be, so modeling a new solid out of the whole range of the guy's moving feet and the pedals would be great to have.

I've searched on youtube and so on - maybe it is a language issue.

Please throw a hint at me... :)

Thank you!

This is not a real part, right? You can create a parametric part that corresponds to the no-go volume. You can exclude that part from your BOM.

Hi Drawoh,

Can you please expand this answear? I am unfortunately still not getting the essence.... :(

Build a part in the assembly itself that is the no-go volume. You can sketch directly on surfaces of assembly components, whatever you need to do to create geometry in the assembly level, you can do. Then you can exclude this part from the BOM since it's not a real part and is only useful for reference.
