The same tool told agents two overlapping 1,000 mm3 cubes held 2,000 mm3 of material, not 1,500. A contained piece could also shift the reported center of mass. The fix measures overlap once and, if that fails, marks the number with metrics.reliable=false rather than passing a sum along. A duplicated imported pump manifold was one of the failing cases.

Analyst note
From the Grok pain-radar digests, Nov 10-11 2026 (Nov 10 8:41 AM ET through Nov 11 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-11: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000

- Before this PR, a successful checked agent CAD edit replaced the accepted model as soon as it finished. Now an agent can run with stage=True, get geometry and check results back with outputs.step left empty, and someone must call promote on an exact saved revision.MCAD · impact 74
- An agent-facing CAD tool's GLB export fails a closed-mesh check while STEP, STL and OBJ of the same part pass. A clean install of agentcad 0.7.2 gives valid STEP (two solids, 73,143 mm3), and STL and OBJ each pass with 1,048 triangles, while the GLB has 248 triangles and 14 open edges. It shows up through both the CLI and the local MCP server.MCAD · impact 66
