To successfully export a group of files in FBX format with the Batch Process Utility add the following key-in to the batch process command file:
$ export fbx $(_USTN_OUT)
This sends the FBX files to the project Out folder.
Alternatively, having created an FBX subfolder in the project out folder:
$ export fbx $(_USTN_OUT)fbx\
The files created will have the original DGN filenames with a .fbx extension.
Other variables that resolve to a complete folder path (that includes the training slash) should behave in the same manner.
