Hi Henry et al,
How do you know what is/isn't supposed to be in a program? I've noticed that the labeling in the reference manual sometimes says a tool is "pro only" -- but I assumed they put that in before developing the "deluxe" line.
Its in my toolbar as well. Its a 3D object, but doesn't render in draft mode, so its only the framework for working in 3D. It seems fair to have it, since there is no 2D spiral tool. Overall, I would rather have the "millions of symbols" it promises on the box, that are nowhere to be found.
I wonder if I could use the helix as a rail to make a screw thread? It would be mostly for appearance -- I'm not actually going to start lathing out my own small parts.
