Hi Alex, I'm kind of confused about the different file formats being used.

I thought the recent thing I was checking was the difference between a DXF file exported out from SolidWorks vs a DXF file exported out from MOI.

There was a difference between them, the SolidWorks one had all arc plane normals pointing upwards in +z. After setting that moi.ini flag then the DXF file exported from MOI should also have all arc plane normals in +z axis direction.

But then your last message has a .3dm file not a .dxf file?
