I'm trying to create a 3d drawing which has a circular pipe that is straight
for a distance the bends along a gentle radius. Ive tried tabsurf, rulesurf,
revsurf, edgesurf without sucess.

how do i do this in R14? do I need a lisp add in ? where do I get that from ? how do I install it?

thanks in advance for your help.
