I have been downloading and using models of fasteners, nuts, and screws from Mcmaster Carr. Up until this point I have just been using them in renderings and have not needed to perform any boolean operations with them. That is until today.
I am trying to take a fastener such as a fastener used for insert molding and subtract it from a parent solid.
The file of the fastener that I am working with has all surfaces as ACIS Solids. There might be 100 surfaces that that are individual objects. One example of this solid can be found here. I typically download the IGES file to work wtih.https://www.mcmaster.com/92398a123
Is there anyway to add all of the ACIS Solid (surfaces) together easily to subtract from a parent solid? I suppose I could do them one at a time but I would be at risk of missing some here and there because there are so many.
