Hi pafurijaz,

Thanks for your feedback!!

Just for info, I exported the solid called "Platte m Nut u Loecher" by selecting just this solid before exporting. So the other elements are not exported and also not visible in the IGES file. Attached in my initial message the 3dm file and the 2 versions of the IGES files.

So actually I still have the issue.

Best regards,

Hi, I made several experiment and you are right the file exported from Moi has other objects, the best way to get a clean file is exporting into sat format and import again into empty scene and export the new one into igs. but if your application doesn't support trimmed surfaces you get the same visualization problem as the screenshot below of my test done with gCAD3D and PolyCAD, i used other application but is hard get a file correct, the best way is making it by network curves in the holed faces.

Here a test made with Blender modeled and converted to nurbs now the file is a correct solid but with a less precision maybe the best way is to do the holes without trimming but making the solid as a separated surfaces and then join together and making a solid from surfaces.
.

I attached several files the clean is without any other geometry ha only surfaces.

Hi sunspeed, what happens if you use Edit > Separate on your objects to break them apart from solids into individual surface objects before doing the export, does that help with your import into your CAM software?

Please let me know if that works and if it does I can make an option for doing that automatically.

re: other objects - those are probably hidden objects. If you do a "Save As" instead of "Export", it will write hidden objects to the IGES file but I think they should be marked as "blanked" objects in the file.

Hi Michael, hi pafurijaz,

Thanks a lot for your help!

I tried to separate the solid into faces as Michael recommended and this directly works perfectly!

This forum and the members are magic!!!

Again thanks a lot,
