Not sure if this is a bug or operator error.
The SKP exported from Rhino is tesselating the cylinder walls oddly. Rhino’s 3DS export maintains the cylinder-ness correctly.
The source geometry is Solidworks exported via STEP AP214. I’ve attached all files. The STEP file contains the whole assembly; the other files contain just one part to make comparison easier.
Any help is greatly appreciated.
