I'm using an evaluation copy of D.LOFT on a Rhino 5 windows machine. I started with a boat hull that I developed free hand before I got D.LOFT. Both the hull side and bottom surfaces of that model would unroll in rhino.
I used that to develop edge curves. D.LOFT would not successfully use those edge curves. I did small changes to the edge curve and it worked well for the hull side surface. I'm getting a good curvature map and the surface unwraps as expected.
Not so with the bottom surface. I have to use some of D.LOFT's options but I do get what appears to be a usable surface. When I try to unroll it, however, I either get an "error unrolling surface" message from Rhino or in some cases with minor curve manipulation it will say "one surface unrolled" but it doesn't obviously show that it has done so. With a closer look it has unrolled only a tiny piece of the surface which I can find if I turn labels on.
Does anyone have a thought on what I might be doing wrong?
