While most users will launch the 3Di2xt parasolids converter from within the 3DVU user interface, it is possible to run the converter stand-alone from a command line.

The syntax is shown below:

3Di2XT.exe [-h|-version|<3Di> <options> [<XT>]]

 -h                        Show this help message
 -version                  Show version information
 <3Di>                     Input 3Di file
 <XT>                      Output XT file

3Di2XT options:
 -progress                 Display a progress dialog box
 -assemblies               Use assemblies to give the file structure
 -unionize                 Unionize extrusions
 -arcs                     Recover arcs from extrusions
 -hierarchy:<attribute>    Build a hierarchical XT file using this attribute
 -vertex_filter:<filter>   Remove vertices closer than this filter value (um)
 -silent                   Display no warning or error dialogs
 -log:<LOG>                Save warnings and errors to a log file
