BUILDER'S LOG
A model can describe a part. Can it edit one?
Models talk about printable parts fluently and misread their geometry. So my Hermes 3D-print skill measures before it edits, and says what it hasn't checked.
What frustrates me about models and 3D printing: they describe a part fluently, then get wrong the geometry that decides whether it prints or fits. On one two-part object I tried, two models both called it a single piece, even after I told them it had two.
So the Hermes skill I’m building treats a description as the weakest evidence. It has two equal tracks: create a part from scratch, or make a local edit to a mesh that already exists. Its 14 design patterns are indexed by geometric problem — a horizontal bore, a bridge, a fit, bed contact — and are source-reviewed candidates, not print-tested recipes.
Editing is the strict part. The original stays untouched. Before an edit: units, the exact target feature, what mates with what, clearances, the protected regions. After: measure, cut sections, re-import, check dimensions, and say plainly whether a slicer or a printer ever saw it. A pretty render isn’t proof that a part prints.
Next: a feature passport from measured geometry, and edits that leave protected shape alone, tested on controlled cases. A workflow I could rely on. Not yet.
