If you can't get the hang of openscad (i'll be honest, it was a little too much for me, and turned what is generally a visual experience for me into a mathematical brain meltdown) I got into Blender years ago and never looked back. Free, completely free and can handle metrics just as well as any cad program, it's pretty much all I use these days.
