Exporting cylinder feature to SKP oddly

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.

Hi Peter - thanks, I’ll take a look. Just fyi, running Purge > UnusedBlockDefinitions=Yes on the 3dm file reduces its size from 5MB+ to about .5MB…

Does BlockEdit then Weld at 30 degrees sort out what you’re seeing?


Thanks Pascal, good to know!
