I have a friend who makes templates out of plywood by pencil and paper. (He uses these to create moulding to form an arc over custom home doorways. Radius?)

Instead of creating this by hand, how would you make basic templates (like arcs and radius) to scale within a Cad program? Is the principle the same for Cad software or does the procedure vary by individual software?

Are most of these programs drawn freehand or can measurements be typed in and the shape created for things like simple arcs and radius cuts?

Importing these files from .dfx into my cam program is not a problem but I have never worked with a straight cad program. I looked for something inexpensive to try this and found DeltaCam, if anyone knows the procedure to create these radius cuts within a Cad program to scale I would really appreciate your input.

Thanks again for your help.
