dutchman (dutchman-cad)MCADConfidence: Medium

FreeCAD 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.
