See attached. I created different size spheres and created an assembly (attached). This is going to made from fiberglass and we need to make a positive mold. How do I remove the intersecting material inside so I have a nice smooth positive mold?
Bob, another option may be available if you were to save the assembly as a Solid Part file and use the "Intersect" tool which is within the Features tool set ... I have been unable to get this to work within the assembly unfortunately.
I believe How to use one Part to remove Material from another Part in an Assembly? will help. In your case that will likely result in extra bodies in each Part file, but you can use the Delete Bodies feature to remove those. Then I assume you should be able to save the Assembly as a Part file for your mold (I've worked on exactly one project that involved casting, and it was a single multi-body Part, so that's outside my wheelhouse).
I guess I forgot to say but the assembly is made up of spheres and I did an Cut-Extude to get the one half shown. Your suggestion works great (I will remember it) but when I select the parts it uses the whole sphere not the Cut-Extrude half
You may be able to use the assembly feature join to create a multi body part, then from within that part use combine with the subtract setting I think. can you upload your assembly or something similar?
You could try offsetting (zero offset - Copy) faces from one part to another (incontext) and then using a cut with surface feature.
A final joined part would merge them all
Another good solution. thanks
Thank you all for your help. I have it done now.
