Nothing John, except the vertical, even seemingly leaning toward the beginner, learning curve to really put that software to productive use. I've started to do something in freecad several times, I don't have it here anymore, but the lack of a plainly marked, multiple step undo gets me into a dead end box that results in a quit w/o save every time. Maybe its there, but I've not found it. If I build a tool changer for the biggest mill I have, I expect that I'll need to use its facility to couple moving parts to see if there's any interference between stuff just to remove the mistakes I'll no doubt make if I just write the gcode to generate the thing one part at a time. Unfortunately, even the src.zip has disappeared from github. But poking around I did find FreeCAD-master.zip, and its copying to ~/src right now. Looks like a pretty long list of dependencies from the wiki on building it. Couple pages if printed. So we'll see if its still buildable on wheezy. And this is probably going to be a long process. So I'll send this and advise success/fail later. Thanks John. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
