Any way to simplify imported step files?

w_curlw_curl Member Posts: 5

I am working with OEM supplied step files. These files are large and very slow to load, often causing onshape to crash. For instance, one of the imports (done as a combine in single part studio) has 721 parts, 684 surfaces and 233,000 curve entities. I really only need about 20 of the parts and surfaces, none of the curves, to aid in my design. Is there a way to simplify? I originally thought that I could select only the necessary parts and do an export to step, re import into new file, but that causes the program to crash when I do this. Any ideas?

    Hey @bill_curl,

    This is a current workaround for this issue:

    Can you try importing using the default options, then go to the top level assembly and exported it as IGES (though other formats would probably be fine) which strips out the curves (since there are no curves in assemblies). Then re-imported it as a Part Studio and it should be much more performant.

    Hope this helps.

    David, do you know if it's possibleto select parts or surfaces in a part studio and then export only those selected entities?
