Unbelievable. Easy to use, latest technology. Real 3D solids, not just drawn as meshes. But supports meshes, too and 2D drafting. Right hand coordinate system. 3D viewer without constraints works as expected. Try that with over-hyped sketchup! Would recommend to anyone.
Promising. But at this point on my Mac only promising. As the old adage said: "If it sounds too good to be true, that in fact is probably the case!" Best of Luck.
FreeCAD has great promise, but it's young and very much a work in progress as yet. I like its user interface and much about the capabilities so far - though it has a few odities and bugs still. However!!! As at August 2015 it allows you to design a single homogeneous part (e.g. a moulding) as a unit. But most real things require an Assembly of parts (e.g. mouldingS + screws + bearings, etc..) - and that's not there yet - which rather scuppers any serious use yet. You can of course design many parts and even place many components on the same drawing. But that's not the same as being able to assemble individual parts into a component/product/composite-part. I know there are some good intentions and good features in the pipeline, like the Assembly module and true Parametric driven* design capability. Providing these are well thought out and well implemented, they'll make it a great product with much potential. [ * FreeCAD at present allows specification of the values of attributes (eg. length, width, height etc.). These can be changed (edited) and redrawing happens. However, to me true parametric driven CAD is being able to use formulae and variables in the attribute definitions, so that changing a value ripples the effect through the whole model, not just one item. ]
