Softimage Xsi: Extruding along a curve question

I'm new to XSI so this may be a simple question...


I have imported two curves: one a boundary curve--say for the outline of a room; the second is a profile curve for a molding that will run around the boundary on the floor. When extruding the curve, it seems that the profile curve positions itself in the center along the boundary curve--regardless of whether or not I change the center to one of the vertices. In the "extrude along a curve" option dialogue, there is an option to change the center, but its not accurate.


The point is, when I'm modeling a floor molding, I want the bottom-corner to act as center so that it lays correctly on the boundary curve.


Unless what I'm trying to do is not possible, the only thing I can think of is that I'm not correctly moving the center.


I know that was pretty long-winded and redundant. Any help is appreciated. Thanks.

I know it is possible to do in 3DS Max where you can outline spline either from center or any other direction. XSI is much less technical then many of the programs...

Hi PolyGru,
As it goes - an image is worth a thousand words.
If you could upload an image with a screen shot of your problem I could help.
Right now I don't understand what is your problem
