A user gets 'At this size the CAD kernel would lose part of the body...' on fairly simple geometry, and the workaround is to export the object as STL, import it into a new workplane, and the chamfer works. They cannot share a repro because the export round trip fixes it.
Recurring agent failure issue in layerling (henmedia)
What engineers report
A recurring agent failure problem in layerling (henmedia) that mostly hits the mechanical designer.
Failure pattern: validation / geometry
Analyst note
From the Grok pain-radar digests, Nov 9-10 2026 (Nov 9 7:41 AM ET through Nov 10 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-10: 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

- Adding microSD slots and cable openings for Raspberry Pi and ESP32 boards meant pulling geometry from a Pi 5 3D model, Pi 4 and 3 B+ DXF drawings, a Zero 2 W drawing read by eye, and BIGTREETECH's model. Several heights are marked as estimated. Enclosure design still depends on stitching board geometry together from whatever each vendor publishes.ECAD · impact 66
- layerling adds a clearance check for print-in-place parts on the same meshes the slicer gets, since the only way to find a stuck pair was to print it.Verification · impact 66
