Sorry it's probably just me, but I can't find a manual for copycat, I want to be able to cut an arc in the xz plane, using copycat, it just doesn't want to do it, I am picking a start, middle and end point, but instead of describing a concave arc on the xz plane,it starts at the start point, and then the z axis rises, until by the time x reaches it's end point it is about an inch above where it should be, it works as a "v" if tell it to go in straight line moves, why not an arc?
Cheers
Mike
