I know the thread is a bit old, but I just came across it.
FreeCAD has been left behind by itself, in the form of FreeCAD-Daily, which has continuous contributions, well .. daily. Pretty much any feature that any CAD package offers is aspired to by someone, somewhere in the user community, so gets developed. Real bugs are found and fixed in hours or days.
All the learning information is out there, but not on the end of a phone. Not actually easy to go up the learning curve, until the concepts stick, but once they do, it becomes a handy thing that is, after all free.
The picture is of a 3CX1500A linear transmitter layout for a ham radio enthusiast friend. Being able to move stuff around, and get to fit, done in computer-land, was handy. We did not model it to the complete finish - just enough to be able to avoid high voltage flash-overs, and decide where all the bits go. There are circuit boards and stuff in the lower pressurized enclosure which need to be screened from the stuff above.
Mostly I use it to display and get measurements of real kit from manufacturer CAD files. Sometimes they need some file format translation, but it works! markba633csi is right. Unless you are a CAD-savvy young whizz-kid, you need the hours to play with it!
