This thread is old, just want to mention for anyone who runs across it, there is a FreeCAD workbench (like an extension) that is not installed by default I recommend checking out: it's called "Curves" and it is a huge improvement in productivity for me, almost as much as FreeCAD vs OpenSCAD in the first place. One of the most powerful things about it is it lets you make two drawings at right angles and combine them to make a non-planar curve, as well as having a bunch of tools for manipulating results. It may require watching some tutorial videos, but this seems to be how you reverse engineer complex curved shapes like, say, cars or other objects.
