But the biggest issue with it is that its constr= aint engine is not as advanced (by way of heuristics) as that of Autodesk or Solidworks. Practically what this means is if you change a base featu= re FreeCAD will give you gibberish instead of what might make sense in context. If you are a hobbyist, and are not very RMS-inclined, then just using a subscription to Fusion 360 will be fine. It is what a lot of hobbyists= use. In fact, even if I were RMS-inclined, I'd probably use Fusion 360 for prototyping and *then* put the design into FreeCAD. Fusion 360 will do stress analysis for free, I think. The other CFD analyses are paid, and can run upwards of $13k/yr, so in case you need them it would be worth it to use FreeCAD.
