FreeCAD suffers from a serious case of open source disease. In theory it can do a lot. In practice its interface is 'unique', its cognitive model is a dog's breakfast, its CAM offering is weak, its command line automation is brittle and poorly documented, and you are going to spend more time solving problems for the code than for yourself. I have directly managed teams of CAD people for most of the last decade. Mostly they use Solidworks, which has its own problems (exceptionally broken namespacing, poor performance especially for cables/fasteners, horrific RCS/VCS offering, ridiculous electronics offering, weak command line support, etc.). Personally, I often use OpenSCAD for simple models. I virtually never use FreeCAD, with few exceptions. IMHO: (1) Blender is better modeler than FreeCAD in many cases, especially with some modern extensions such as https://www.cadsketcher.com/ https://www.cadsketcher.com/ https://blenderbim.org/ https://blenderbim.org/ https://github.com/kevancress/MeasureIt_ARCH https://github.com/kevancress/MeasureIt_ARCH (2) It is far more useful to learn Blender than to learn FreeCAD, since that will allow you to achieve animation, parametric models, point clouds, geospatial modeling, etc. where FreeCAD is basically functionally limited to working with solids and the output of conventional artifacts such as STEP files and drawings. (3) Drawings themselves are becoming largely outdated as the leading edge of industry seeks to move from "CAD->drawing->CAM-based production" to "CAD->CAM-based production" to finally rid itself of human errors of interpretation. This is of course a long term goal, and will never wholly succeed, but the migration has begun and the writing is on the wall.
