# Geometry QA for architectural concept models## Evidence hierarchyUse several evidence sources:1. live measurements from the current Rhino document;2. saved `.3dm` existence and reopen checks;3. static review of the exact generator on disk;4. viewport captures and their metadata;5. implementation reports.Implementation reports are lowest because they often describe an earlier revision. A generator's own JSON is useful but is not independent verification.## Required checks### Inventory- Count all active objects and objects by layer and geometry type.- Confirm every owned object has one unique semantic name.- Detect objects on wrong or missing layers.- Distinguish physical solids from reference curves/surfaces.### Shape validity- Require physical Breps or extrusions to be valid and closed/solid.- Detect degenerate dimensions, zero-length axes, and empty geometry.- Detect exact duplicates using type, location-aware bounding box, and volume/length fingerprints; confirm suspected duplicates geometrically before deleting anything.### Dimensional intent- Measure the physical bounding box separately from the full scene bounding box.- Recompute station positions and spacing from geometry.- Measure offsets from reference axes, not only from neighbouring members.- Check angle vectors for louvers and sloped members.### Contact and clearance- Use Brep/Brep intersection or distance for ridge, beam, and column connections.- Test an opening with a guarded 3D clearance volume that extends through the occupied depth.- Ignore permitted boundary contact while rejecting penetration into the clear interior.### Parametric behaviour- Rebuild twice with the same inputs and compare metrics.- Change independent input classes without changing construction code.- Confirm expected deltas and invariants explicitly.## Defect sensitivity setA serious QA plan should be able to detect at least:- a small global or single-member offset;- a wrong layer or missing name;- an open or invalid solid;- duplicate geometry;- unequal frame spacing;- an incorrect clear opening;- a sloped member that nearly reaches but does not contact its support;- a parameter value that changes in JSON but not in geometry.## Visual reviewCapture at least one perspective and the relevant elevations/sections. Confirm the view contains all expected visible objects and a plausible scene bounding box. Pixel review detects composition and obvious gaps, but it cannot replace measured geometry checks.
