Z Normal in DXF-DWG Export

  Hi, Recently SpaceClaim starts to export DXF/DWG in different way than before. Circles (holes) in DXF have a parameter called "Z Normal", it can be 1 or -1 (in our cases). Before latest version in the same exportation the Z Normal was 1 (or -1) for ALL circles. All circles had the same parameter. Now, with latest release, it's not the same. Some circles have "Z Normal = 1" and other "Z Normal = -1". This causes in some software (for Example Bysoft from Bystronic, one of the most important sheetmetal laser producer) errors. I'm not an expert on AutoCAD and DXF/DWG file structure, but this propriety is visible in AutoCAD. Here the external circle haz Z normal -1
  Here the internal circle has Z normal 1
  Result on Bysoft, the shape isn't connected, seems Z-1 circles are mirrored
  Here the mirrored circles are visible, but sometime the risk is to produce part without some hole. Can you investigate with programmers? Thanks

  Hello DrkAngl
  
  Could you try changing the SpaceClaim to Autocad export Translation Technology setting from 'Teigha' to 'Autodesk RealDWG' ? (refer image below)

  Here the 2 different DXF file (one created with Ansys SpaceClaim 2021 and one with SpaceClaim 2020).
  Can you ask to programmers?

  Subashni I downloaded 2021 R2 Version and tried to export a DXF and I get the same result (mirrored holes).
  
  Can you verify with developers if they think the bus is fixed?
