Any particular use case? Maps?
No, mechanics. When I start thinking about moving parts, my viewpoint is the center of a ball joint or the axis of a revolute joint, if one of these could be involved. My ideas in 3D are then based on angle, height and distance, or two angles and one distance, and not just cartesian.
(Maybe it's because I make a living as programmer for industrial robots for > 20 years, so I'm used to mix rotational and cartesian coordinates in my spatial sense.)
It's just that I somehow miss some tools. They mostly could be replaced or simulated by a different workflow, but with bigger effort.
For one example, right now I need a (rectangular cross section) irregular path in the surface of a sphere section, like milling in a ball. It's easy to imagine, easy to describe, not too hard to calculate, but a bit cumbersome to realize in FreeCAD. (Please no advice how to do particularly THAT in this thread, I will find out. I'm just speculating about my toolbox here.)
