I've been using DesignCAD for years, but TC rendering is a lot better. But I'm going crazy getting use to TC. Simple things like trying to move the working plane: it rarely snaps where I want it. Can you make a polyline go along the x-y plane then up the y-z plane then across the x-z plane? When you tab to the inspector bar all I see is length and angle - how about xyz cordnates. It's also odd that Z is up, most graphs y is up and z is depth.
