Definitely quite usable for modeling parts and basic assemblies. I use it almost exclusively now when working on community hobby projects, so as to make sure everyone has access to the development tools to make their own modifications. But it's definitely behind the curve in terms of how friendly and discoverable the user interface is. It's a powerful modeler, but I'm not sure that it's in a good state to be used by a large engineering team on multiple large projects. In particular, a lot of the PDM options for FreeCAD seem sort of questionable; for better or worse, a lot of organizations are going to need it to interface with their current data management software. I haven't seen the effort to do that yet.
