the little orange blocks are your ears, so if they're real far apart you get better resolution on where a sound could be coming from, but no matter what if you can only do time of flight with phase/amplitude you can only discern location down to a band, not to a point or even a collection of points.
I learnt how to do my 3D modelling on a borrowed student copy of SolidEdge, then moved on to Autodesk and SolidWorks, and I'm now trying to pick up FreeCAD, which means that I really struggle with the idea of primitives based modelling. I much prefer the idea of drawing sketches and revolving/extruding/sweeping, mostly because using dimensioning to fully-define objects is hella cool. Blender tutorials start with "just drag a cube out into the void" and that confuses me.
Openscad seems nice because unlike a lot of visual primitive modellers you still start with dimensions, so there's a degree of irreversible precision baked in.
I should still learn blender.
@kalium Blender's not really good for set operations (union/difference) at least if you care about the output mesh being tidy. And its revolution tool is for some reason hiding under 'screw with 0 distance traveled per screw'.
On the other hand the modifier stack is so good for a certain type of procedural stuff that I use it to make 2d things (by building them on a plane and baking into a texture)
I learnt on ProDesktop 2000i², so I'm even more outdated...
