I’m trying to draw a simple 2D CAD drawing to use with BlenderCAM. All I’m trying to do is draw a simple box with a circle in its interior. This is to represent a metal plate with a hole to be milled out. If I choose a bezier curve, I can get a curve, but making it straight, a specific length, and lining up with other ‘curves’ is difficult at best.
I’m sure I’m making this much more difficult than it needs to be. Any pointers on doing 2D CAD in Blender?
