I'm trying to produce this loft but the rail I really need it to follow won't produce any results. The other ones on the 3d sketch will work just fine but not the regular sketched one. It seemed to work when I made the rail a straight line but I need it to follow the edge of the surface which is a line, tangent to small r3 arc, tangent to line and connected through projected geometry from the original surface sketch.
I mostly understand the loft tool from all the other posts but can't seem to understand why this one won't work. Any help is appreciated. Thank you!
