| Even when a mesh looks perfect, it collapses the things CAD/CAM depends on: | ||

| - **No analytic intent:** In CAD, a hole is a cylinder with an axis, diameter, depth, and often a spec (clearance, tapped, counterbore). In a mesh, a “hole” is just a bunch of triangles arranged in a loop. There’s no axis to reference, no diameter parameter to change, and no stable feature semantics. | ||

There was a problem hiding this comment.
Maybe "In a mesh, a “hole” isn’t empty space, it’s just part of the mesh defined by surrounding geometry." would offer more clarity for that sentence. It confused me when I first read it.

A few somewhat opinionated changes to the latest post. Happy to discuss or discard.
