That's polygon modelers' job. They start from basic geometry like a cube or a sphere, and add details by subdividing, extruding, beveling, working on surfaces and edges. The end result often shows lots of angled parallel lines.
Other two major types of 3D modeling are parametric CAD modeling and sculpt polygon modeling. Sculpt is a relatively new method suited for modeling natural objects like an animal bone, and parametric CAD is extension to good ol' hand drawn mechanical schematics.
If you know what to look, you might notice that polygon-modeled models often has an origin _point_ at its center of gravity towards which cross section of the model and density of surface details increases, and that parametric models has an origin _plane_ at an "end" where it extends from which tends to define average cross sectional area of a part. This drone is a mix of those two methods.
... And the real reason why I'm writing this comment is because sometimes I don't like when modelers do general aesthetics first and add internal structure as mere flavoring, making it "boneless", like all those Star Wars ships. Everything mechanical are "added details" in Star Wars mechs.
I think your complaints come from something similar to what I have problems with. Photography cameras were always machined so they are always drawn in CAD with mechanical principles first and surface details to follow.
