I am trying to design a barrel cam. This works well with lofting, but I am not so sure about the mathematical accuracy. I am used to making cams like this with 1/4 degrees resolution - much too cumbersome in lofting. Is there a way with "_sweep" to constrain the profile (2d polyline) so that it stays e.g. parallel with the Z-axis?

You can generate the curves with _SPLINE or _HELIX (German: SPIRALE ) to be used for _SURFNETWORK (FLÄCHENNETZ).
Look to my drawing, left side is prepared data, right side is after running _SURFNETWORK.

Well, as nice as that sounds it is moot, however, since I can't open your drawing. I only have Autocad 2006 installed and did this on somebody elses machine, just to try it out, but thanks.

Sorry, here is the AutoCAD2011-forum and you haven't mentioned that you need it for 2006.
Anyway, imho Udo at www.cad.de has also shown you the steps to go (I think it's the same project, isn't it?).
