When I export closed polysurfaces (solids) as a step file and re-import them they tend to become open polysurfaces. I‘ve had this issue before and so far I could not find a solution. I tried all the options already but that does not seem to make a difference.
The geometry is usually very complex and has several thousand surfaces.
I use this way to create geometry for a customer using inventor. Sometimes they can ‚repair‘ the geometry, sometimes they can‘t.
I couldn’t find any more clues in the internet so I was hoping someone here has any ideas.
Thanks a lot!
