I've found the same thing with regard to workflow - I find it really weird when people say it's nothing like any other CAD programs, because it really is. You start with sketches and build up from there. Yes, the spreadsheet feature is amazing! I couldn't believe SolidWorks forces you to buy Excel to do the same thing, which is crazy. The spreadsheet integration in FreeCAD is great - with the macro that handles the reference labels.
