I've purchased the registered version of SheetCAM (and Mach3). I've been through the Sheetcam tutorials quite a few times - and they make sense!

The problem is that I don't have any CAD software yet to create some basic, 2.5d parts to learn with in Sheetcam. I've downloaded a lot of the free CAD but haven't been able to make anything (I'm new to both CAD & CAM).

Does anyone have any DFX files of things like t-nuts, a TAIG spindle wrench, or anything? Just looking for some files where I can go through the process of pocketing, drilling, etc then exporting to mach 3.

Thanks!

John
