Recurring hexera-platform (hexera-core) errors, by impact

  1. 1A platform permission bug (403s on every mesh pass, no actAs or image-pull grants) was reported to the user as a fault in their CAD ('two faces lie on top of each other'), after 39 minutes and a booked 961 GiB VM. The mesh size itself came from boss pockets cut exactly to the tube's inner radius, leaving zero-thickness skins.Verification · Agent failure · 1 report74
  2. 2A STEP face-name reader segfaulted on CATIA V4 and Creo assemblies in a 237-assembly test, crashing the staging process and taking the whole CFD or FEA run down for a name lookup that is only a convenience.MCAD · Agent failure · 1 report74
  3. 3Face-number zone ids collided across parts in 44 of 46 real multi-CAD assembly plans, so a fix aimed at one part's thin wall refined a different part's thick wall. On a bus door, W9 was both the 80 mm wall and the 5 mm glass, and the glass was left short.MCAD · Agent failure · 1 report74
  4. 4Hexera staged an AutoCAD STEP assembly at 1/305 of its size after mishandling a FOOT unit declaration, with the thinnest wall read as 0.025 mm and two parts floating.MCAD · Agent failure · 1 report74
  5. 5Inventor's inch spelling was unknown to the checker, which fell back to metres, so a 50 mm hub read as about 50 um and the mesher crashed with a numeric error; unit-less STEP files failed the same way.MCAD · Agent failure · 1 report74
  6. 6Before a fix, a CAD-to-FEA shell pipeline left 190 damaged surface files open without saying so and wrongly welded 98 more, across a 2,212-file test set. The hexera branch adds a sewing ladder, catches faces written twice, and lets notes like 'stitch gaps up to 0.5 mm' set the limit. Afterwards: 0 silent, 0 wrongly welded.MCAD · Agent failure · 1 report66
  7. 7Hexera staging crashed when native CAD code segfaulted inside the run's own process, losing the run each time.MCAD · Agent failure · 1 report66
  8. 8The FEA tool left parts floating in 11 real multi-CAD assemblies because faces within the gap limit that never faced each other were never jointed.MCAD · Agent failure · 1 report66
  9. 9Two assemblies, a 406-part laser cutter and a biped robot, were killed at 32 GiB before meshing, because staging wrote metres while OpenCASCADE tolerances are tuned for millimetres.MCAD · Agent failure · 1 report66
