I, mew to LW and was wondering if itt was possible to do a rail extrude with more than one surface. I have tried to do it with different size disc, square and disc using the same layer or different layers but so far cant do it. Is this possible?

Yes, it is possible. Instead of starting with a single polygon shape you'll want to start with a chain of two-point polygons (make a box, select the ends and press k to kill the polys, select the points on one end and press delete). You can select the 2pt polys and give them surface names.

Extrude as normal.

Now you have twice as many polygons as you need so use the 'unify normals' command (This makes sure all the polys are facing the same direction - it is called 'align polygons' in older versions of LW) and then the 'unify polygons' command (This eliminates all the polygons that have the same points and are facing the same direction).
