I’m looking to get some mass-produced parts from overseas, but the vendors seem to only be able to accept files as STP, STEP or IGS files. I’d never even heard of these file types until they mentioned them. So, I have two questions:
1) What exactly are STP, STEP and IGS files that makes them different from STL and OBJ files?
2) What software can I use to convert my STL and OBJ files to STP, STEP and IGS files? Is there anything readily available?
Any help anyone can offer would be great.
