ATARYS-LABandClaude Opus 5.5
f7494840dc
VIEWPORT group 51 was not read, so a twisted viewport came back untwisted and a DXF or DWG saved by CADCraft wrote it without its twist; AutoCAD then showed the sheet rotated. The twist is now read (finite angles only, brought into one turn) and written when it isn't zero; the DWG bridge already carries group 51 both ways. The display and plots don't apply it yet.
