NX Unable to export contour flange

When trying to export a solid with a contour flange using the "Export Part" function, an error is output and the export fails.

Reproduced Steps:

1. Create a SB Tab and SB Secondary Contour Flange

2. File > Export > Part

   -1. Feature Parameters = Retain Internal or Retain All Parameters

   -2. Other options are OK for reproducing

The behavior is due to NX problem and will be fixed in NX 2306.

Workaround: Perform 1 or 2 below.

1. Specify "Remove Parameter" in "Feature Parameters" during exporting.

2. use other export commands such as Parasolid.

This problem has been occurred since NX 1899.

Occurrence condition : Export bodies with SB Secondary Contour Flange features. (This problem does not occur with SB Base Contour Flange.)
