Lofting Problems

I am trying to loft a triangle around the path of a helix. I want the top point of the triangle to be facing in such that the ouside surface is flat (in the veritcal direction) for the entire helix and I have the two triangle cross sections oriented to do as much.  Whenever I try loft it, autocad associates sides of the triangle that aren't supposed to connect causing the triangle to twist along the path.  Is there a way that I can easily tell autocad which sides I want to connect?

Guide curves mapping point to point.

 

Is there any reason you aren't using Sweep?
