Recurring dutchman (dutchman-cad) errors, by impact

  1. 1A tool that rebuilds a feature history for SolidWorks parts checked the rebuild against the original geometry by volume and area only. A body in the wrong place, or turned a quarter so its extents swap, has the same volume and area, so simple sketch-and-extrude blocks rebuilt 6 mm off, or rotated, came back 'verified' with the wrong shape. The fix pairs bodies by box centre and compares every box coordinate within a tolerance, and keeps the history as partial when they disagree.MCAD · Agent failure · 1 report74
  2. 2FreeCAD Assembly documents often hold links to Bodies in sibling .FCStd files and no geometry of their own; conversion went from 0 of 32 to 32 of 32 assembly recipes once links were resolved across files, with volume within 0.0001 relative and bounding box within 0.01 mm. Missing targets and cyclic links are now reported as omissions instead of failing the whole thing.MCAD · Agent failure · 1 report74
  3. 3FreeCAD stores horizontal and vertical sketch distances with a sign; Dutchman linked the positive dimension to the signed parameter, SolidCraft rejected 'dimension value -2.5' on replay, and the whole feature history was flattened. Across 349 FreeCAD recipe files, verified histories went from 159 to 167 with the fix, so more than half still do not carry over.MCAD · Agent failure · 1 report74
  4. 4Converting a public 88-component SolidWorks assembly ran out of memory at 24 GB because each part was read every time it was referenced. Reading each once brought it to about 4 minutes at 14 GB.MCAD · Agent failure · 1 report66
  5. 5FreeCAD spreadsheet formulas and parameter references lost their expressions on conversion even when the identity data was there.MCAD · Agent failure · 1 report66
  6. 6One feature that cannot convert to editable history used to throw away all earlier features on import; now the editable prefix is kept beside the original shape.MCAD · Agent failure · 1 report66
