Recurring quiddity-rust (pzfreo) errors, by impact

  1. 1Feature identity between two STEP revisions is rebuilt each time from fingerprints and Hungarian matching; it breaks on pattern instances with identical neighbourhoods, re-laid patterns, and features that change kind. They point at SpaceClaim monikers, which record identity at edit time, and note you cannot get that between two independent STEP exports.MCAD · Agent failure · 1 report74
  2. 2A feature recognizer crashed on two real Fusion 360 parts: one was Autodesk's own STEP export of a Fusion design, where pocket walls formed several cycles joined only through a floor, and the other came through a third-party converter, where rounded footprint bounds gave one wall two roles, and those cases now produce visible refusal records instead of panics.MCAD · Agent failure · 1 report66
  3. 3A STEP PMI reader folded three Ø19 sizes on separate lands into one datum, so the downstream tool could not number one of them and shipped a temporary writer patch to cope.MCAD · Agent failure · 1 report66
  4. 4FreeCAD STEP exports often hold the same body several times on top of itself, multiplying every feature count on the generated drawing; the earlier fix covered files where every body coincides, but when only some do (a plate plus two stacked copies of a pin) the drawing is still made from the whole file with a warning.MCAD · Agent failure · 1 report66
