I'm using TC deluxe v14 and have no problems in 2d. I've ventured into some 3d and don't know much.
If you can follow this, I want to machine a half an apple for a sign. I made an apple in 2d, gave it depth by converting to 3d and giving it 1 inch of depth.
Now how do I round the apple so it doesn't look like it has square edges?
