Hello, I am using code in ZPL which include exporting of objects (non-sequential mode) to CAD files-created by Zemax community:

SUB export
  IF PureNSmode == 1
    start_number = num_objects + 1
    end_number = new_object - 1
  ELSE
    start_number = surf_no
    end_number = surf_no
  ENDIF

# Export the solid objects as CAD files
  VEC1(1) = ext           # CAD file type
  VEC2(2) = 8             # spline segments
  VEC1(3) = start_number  # start surface
  VEC1(4) = end_number    # end surface
  VEC1(5) = 1             # ray data layer
  VEC1(6) = 0             # lens data layer
  VEC1(7) = 0             # do not export dummy surfaces
  VEC1(8) = 0             # do not export surfaces as solids
  VEC1(9) = 5             # ray pattern NONE
  VEC1(10) = 0            # number of rays = 0
  VEC1(11) = 0            # wavenumber
  VEC1(12) = 0            # field number
  VEC1(13) = 0            # do not 'delete vignetted'
  VEC1(14) = 1            # dummy thickness    
  VEC1(15) = 0            # do not split rays
  VEC1(16) = 0            # do not scatter rays
  VEC1(17) = 0            # do not use polarization
  VEC1(18) = 0            # use the current configuration

  !PRINT "  Saving to: " file$
  EXPORTCAD file$
# Erase all the extra objects
  !PRINT "  Erasing objects #",num_objects+1,"-",new_object-1,"...",
  IF (new_object - num_objects) > 1
    FOR i, num_objects+1, new_object-1, 1
     DELETEOBJECT surf_no, num_objects+1
    NEXT
  PRINT
  !PRINT "DONE"
  ENDIF
  UPDATE ALL
RETURN

Everything was fine until I start to use new version of ANSYS OpticStudio 2024r1. Exported CAD files are corrupted and miss there information (and subsequently they are incorrectly imported into cad software)... also results file has different content:

2024r1 (STL file):

   vertex       80      200        0
   vertex      -80      200        0
  endloop
 endfacet
