Settings to confirm in your conversion engine

  • Target version / schemaDWG: AC1027 (2013) is the most widely readable. STEP: AP242 keeps PMI/GD&T, AP214 keeps colours and layers.
  • UnitsConfirm source units before converting — unitless DXF/STL files are the most common cause of 25.4× and 1000× scale errors.
  • Tessellation (mesh outputs)Chordal deviation ≈ 0.01–0.02 mm for 3D printing; 0.1 mm is usually enough for web/visualisation.
