Hi, I have a double-curved, saddle-shaped surface and I would like to take the edge and extrude it relative to the surface normal. No problem, just use the “fin” command. But I also want to add a 5-degree draft angle to the fin as this will be for a mould. It would be great if the Fin command also had an angle option between 0-180 degrees. I can imagine doing this in GH but it would be hard to maintain tolerance efficiently. Does anyone know a native Rhino command that does this? Obviously the corners won’t match anymore, but I can manually resolve that.
The closest I can get is using Pipe on the surface edge, drawing the line profile at the correct angle and then doing sweep2 using the surface edge and the edge of the Fin. I can tell this isn’t accurate as the new surface edge doesn’t lie on the pipe. Essentially I want to rotate the edge of the Fin around the original surface edge and then loft.
