>How many hundreds of dollars does it cost?

Sadly, you're missing a zero.

Out of the whole bunch, FreeCAD is probably the best open source solution.

If you don't mind pending a bit of $, and need something parametric, then Alibre CAD ticks a lot of the same boxes as F360. Windows only though.

If OTOH you don't need parametric design, I've gotten pretty far with Rhino3D, although again that is Windows/Mac only.
