Hello,

Thanks for help.

The only profile youl could strude on a 3d Polyline is a circle.
You can draw any curve on 3d

On Cadalog at www.cadalog.com you should be able to find 3DSPIRAL.LSP
or on Autodesk User Group International at www.augi.com in the exchange section you should be able to find HELIX.LSP
and these should help you.

You have to follow the directions carefully as to how to use it.
The problem with all other spiral routines is that they twist your profile as it is extruded along the path.
Here are some examples of Fucarro's helical exrusions.
Off topic-he has some interesting routines he wrote for a telephone cord and a shell that is worth checking out.
