Feature request: convex hull

The convex hull operation from OpenSCAD is extremely useful for quickly drawing up simple (and not-so-simple) mounting-plates and whatnot. Examples at https://hackaday.com/2018/02/13/openscad-tieing-it-together-with-hull/.

I'm limited by the freecad api.
How to create a hull in freecad? If the GUI can do it, I may be able to script it.
