Like the title says, I want to import a model that is an .IGS file, and import it into its component parts. I can get it converted to an .STL, and it opens up fine, but there is no splitting up components. any ideas? I want to be able to 3d print them as components, not as a solid chunk
Can you request an STP file instead? There is a chance that you might get multiple solids with that format, assuming the original CAD file contained multiple solids.
IGS may not contain multiple solids, instead only trimmed surfaces, which need to be stitched together to form solids and typically you would need a CAD application for that.
You could get a trial of Moi3D, which is a relatively inexpensive CAD app and has superior nurbs to mesh conversion.
