Hi,
I have a question. Is there a way, via the C++ SDK, to use “SrfSeam” so I can align a blue border with a green line, as shown in the image?
Tks.
That green curve doesn’t look like it could be an isocurve of the red surface (assuming the blue curve is an isocurve). A seam is a boundary isocurve of the underlying surface – i.e. the entire untrimmed side of the surface. I don’t think it can be a trimmed edge.
So in your image, if the red surface has the blue seam, you will need to modify the CVs of the surface to deform the blue curve to match the green curve. Maybe it will be enough to just project the edge CVs to the green curve?
Another thing to look at, RhinoChangeSeam (here) is there to change the seam from one isocurve to another, basically shifting the surface in its parameter space.
