A 3.5e-10 mm boundary edge let the STEP export succeed while OpenCascade rejected the solid. Export now repairs it or refuses before writing any bytes.
Recurring agent failure issue in catallax (BohnBawerick)
What engineers report
A recurring agent failure problem in catallax (BohnBawerick) that mostly hits the mechanical designer.
Failure pattern: validation / failure
Analyst note
From the Grok pain-radar digests, Nov 8-9 2026 (Nov 8 8:41 AM ET through Nov 9 6:41 AM ET digests plus the Haitch editions). Verified live 2026-11-09: 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

Evidence
More recurring errors in catallax (BohnBawerick)
- a CAD kernel wrote invalid STEP for full spheres and tori; OpenCascade read the sphere back with one edge and no pole edges, and the torus failed to import.MCAD · impact 66
- STEP export wrote full cylinders, through-hole walls and cones with two ring wires but no seam or UV associations, and raw OpenCASCADE import rejects them.MCAD · impact 66
- STEP has no edge for a sphere pole inside a face, so raw import rejected these faces, and the fix moves interior sphere poles onto export-only STEP caps.MCAD · impact 66
