I'm not sure that's analogous to "best practices" like "do not repeat yourself (DRY)" or "don't use GOTO". These are little more than stylistic choices that claim to offer more maintainable code. Comparable "best practices" in other engineering fields would be along the lines of "do not chamfer/fillet until the end of modelling" (one I have heard before).

Analyzing a CAD model as you describe is more like running a compiler or type checker on code already written, which is the norm in software too, but is not within in the vein of the topic of discussion.
