I have designed and modeled the letters shown below. They have a slight dome on the top of them created using the "create shape from vectors" tool. Then added a 9 degree draft. I need help figuring out a way to toolpath and not have to turn all the waste material outside the letters into chips.
I can profile around the outside and the inside as shown in the second photo, but when I do a 3D toolpath to get the curvature on the top of the letters Aspire wants to machine all the waste material as shown in the third photo. Is there a way to not do this? I assume one of you very experienced guys/girls knows how, but I haven't been able to figure it out.
