if it won’t export, Rhino should flag the object as bad, which it doesn’t

Thanks Mitch, It’s the same case as in this thread:

(boolean split / split / Export selected) these commands are failed on object which is generated by (sweep1 or extrude along curve) commands

Hi - you are reporting different things in the same thread, so this is getting complicated to answer. At any rate, in the file where the object is not exporting to DXF, the profile curve has a segment with length = 0. Rhino doesn’t complain when it extrudes this (and also makes a degenerated surface), but this is caught when it is exported. [image] When you run the SimplifyCrv command on the profile before extruding, the command will result in an object that you can export to DXF. I’ll get …

I’ve got it on my list…
