I want to create a basket from arrayed polygons by applying the pipe2 command. I am using the latest v3 beta, and the pipe2 was receiving OD=1, ID=0.

Strangely, only a couple of the polygons are piped, the others won't. I can't see a difference between them, but something is not working.

On a sligtly linked question: I need (for printing) a volume and used pipe. But if I wanted to have a square pipe or an I-beam instead, what command would I use?

Thanks a ton!
