Recurring ORCA (IssueLab-Inc) errors, by impact

  1. 1ORCA IFC viewer stores vertices as float32. Autodesk Snowdon Towers sample sits about 418 km from zero, where float32 steps 31 mm, so 200 mm ducts came out square. The demo models sat near zero, which is why nobody saw it, and the fix draws relative to an origin picked from the median placement.MCAD · Agent failure · 1 report74
  2. 2ORCA's hand-edit tool worked on its demo model but broke on real Revit IFC exports, where pushing one face dragged joined parts with it.MCAD · Agent failure · 1 report74
  3. 3ORCA found a washer waste arm running dead level through a 106 mm cold-water stub, 24 mm from its bend. Every move was refused because each pipe is held by a fixture at one end, and drains may not step. Neither of the earlier auto-fixers had a fix, and the answer is to tilt the drain about the cap that stays, which also fixes the missing fall.MCAD · Agent failure · 1 report66
