It's my first post here and english is not my mother tongue so be understanding.
I have a complete motor from a supplier in a heavy STEP file (171 Mo)
I'm able to open it (takes about 3-4min) and it's composed of 7159 surfaces and 4 imported bodies. I can't even make a repair/diagnostic on it... it crahes everytime.
I've tried to export to STL and reduce faces with MeshLAB but I lose to much details and lose originals plans. I've tried to "defeature" overnight but it still crash.
I'm looking in a way to keep the exteriour "shell" but suppress the internals part/surfaces...
Thanks in advance
