XSI Polygon Winding?

[archvilell]

I watched the majority of a neat tutorial on how to make a Colt 1911 (made by DeSty), and I've decided to try to follow the steps, but apply it to my Beretta M96 (same as an M92 except .40 S&W instead of 9mm). I created the outline of the gun, made it a polygon, duplicated it, then merged the two. I'm trying to bridge the gap between them so I can get the three-dimensional look to it, but I get an odd message.

It looks like this:
<see attached>

It says that the polygons are "winding" and that it might have to make two boundaries. I have never seen this, have no idea how it happened, and have no idea how to fix it. I tried reduplicating it (thinking maybe XSI screwed up the duplicate) but that didn't work. Then I tried moving points so theyre exactly the same x and y, only differing in the third dimension, but that doesn't work either. I don't know what is wrong. Anyone have any ideas?

P.S. if anyone knows of some active XSI forums, could you let me know, so I don't have to bog down these forums?

you'r getting that message because the poly's your attaching have different normal orientations, try reversing the surface orientation of the poly you duplicated, then try again.

As a tip, use the "n" (poly creation tool)

Thanks a bunch. Now I can go back to work.
