Three dimensional line from start point to XYZ.

Again, a three dimensional curve ending at an XYZ position.
Also have the ability to specify arcs on th XZ and YZ planes.

A Gcode export would be useful - generate and test the program on a desktop
stepper machine, then run it on a conventional machine. Or email the file to
another hobbiest - or machine shop.

Support for a fouth axis (or an indexer) would be handy for gear cutting.
