I’m trying to create a rectangular surface with a quarter of a circle is subtracted from one vertex. I successfully create the surface with correct geometry but i cant get the control point data since the program defines the model as a polysurface (showed as 1 in model). Is there a way that i can create this model as one surface and get the control point data (showed as 2 in model). Model.3dm (40.9 KB)
Thank you for your reply. I successfully merged two polysurfaces into one and get the control point data. If may i ask another question, can i rebuild this surface to get the control points approximately as shown in #2? Rebuild command seems to change the geometry completely.
