This is a continuation from my previous thread "arched top exterior door". I haven't started this project yet however I'm trying to familiarize myself with the "extruder" feature to mill the arched door molding. I am not making much progress and becoming more confused. I drew a simple profile to practice, but can't seem to get past this because there are open vectors and I can't close them to create a tool path. Do you create a V-carve, profile toolpath or a pocket toolpath? In B. Young's corner there is a nice 3D image. I assume this is the preview, but how do you get to this point? Has anyone done this who could provide some guidance? Many thanks!
