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

Here the files (you can try to generate the DXF from the STP)

Hello DrkAngl

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

Customer tried to set Autodesk RealDWG as export format but it not solved.

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