Fastener From Individual ACIS To Solid For Subtraction From Parent
Read 262 times

Hi All,

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.

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.

Best Regards,

I usually download the "3-D SAT" format, because SAT is the ACIS native format and should work okay in TurboCAD Platinum.

I never had a problem using McMaster-Carr's STEP files, either.

I 3D Subtracted a #6 screw's thread from a screwdriver design, printed it in plastic and it assembled hunky dory.
