> FreeCAD has enormous potential.

I absolutely agree. I'm especially interested to see the future of integrations with computational fluid dynamics & finite element analysis (OpenFOAM for the former, Calculix & Elmer for the latter.) For example, one user on the forum was able to simulate the multi-mode heat transfer of a hot metal cube in a wind tunnel (but unfortunately I can't seem to find the post!) Another was looking into integration with KiCAD to simulate the thermal behavior of custom boards.
