STEP import in cad-rust-app dropped part names and colours, and the project needed a colour.py script to put the Onshape colours back. Bodies came in grey and named Part N. Colours were written as linear RGB, so #ff8000 showed up as #ffbc00 in other programs and on re-import. The fix reads names and colours through OCCT's XCAF reader and never overwrites names set by hand.

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

Evidence
More recurring errors in cad-rust-app (JonasMerrell)
- Before this fix a sketch silently stayed on its old plane after a parametric edit, and one missing edge dropped a whole fillet; now face and edge references are named and an unresolvable one is an error. Sweep, loft, imported STEP and pattern copies still resolve by point.MCAD · impact 74
- A DXF $INSUNITS of micrometres came in 1000x too big, elliptical arcs crossing zero imported as the opposite half, mirrored entities flipped X, and one bad ASCII STL vertex shifted every vertex after it.MCAD · impact 66
- In a PCB GUI bug sweep, drill sizes 0.8 and 0.8004 both printed as C0.800 but stayed separate tools. References past a quarter turn printed upside down on silkscreen Gerbers, and tall boards were cropped in PNG renders.ECAD · impact 66
