Recurring cadcraft (storytold) errors, by impact

  1. 1OVERKILL decided whether objects were equal by rounding each number to the tolerance. With 0.01 tolerance, circles at 80.001 and 80.003 merge, but circles at 50.004 and 50.006 both stay. It happens at the default 1e-6 too, and more often at the coarser tolerances people use to clean up imported drawings. The PR spells out the cost: a duplicate circle left behind gets cut twice on a laser or plasma cutter. The fix compares the numbers directly.MCAD · Agent failure · 1 report74
  2. 2Booleans on thin-strip-tessellated curved meshes produced about 4,800 open and 5,900 non-manifold edges at 11 to 17 seconds each.MCAD · Agent failure · 1 report66
  3. 3Older AutoCAD drawings keep a moved dimension's offset in DXF group 12, which CADCraft ignored, so the dimension draws far from what it measures and plot-to-extents shrinks the sheet. The reporter says about 12 percent of a set of real production drawings are affected.MCAD · Agent failure · 1 report66
