I am trying to create a “lip” for reinforcement along an edge but keep getting a bad join as seen in the picture. What I am trying to do should be apparent in the attached Rhino file.
I duplicate the edge and then modify the curve to create my second rail. I create a cross section profile and then Sweep 2 to a point on each side of the profile curve. All seems to go fine until I join the surfaces. I have fiddled with the tolerance and tried every option in the Sweep2 dialogue but nothing seems to help. Insight into what is going on would be much appreciated and/or an alternate approach.
