1. Download and Install the application.

2. Launch Revit and open a model.

3. Go to the ‘Add-ins’ tab on the ribbon bar. It contains the following buttons:

   • Export

   • Preferences

   • About Us

4. Exporting the Model:

   • Click the ‘Export’ button to export the model to a .jt file.

   • A Save As dialog will appear. Specify your desired directory and filename.

5. Setting Preferences:
   Click the ‘Preferences’ button to configure output options:

   • Write Out Point Bodies (Points): By default, points are not exported. Enable this option to include points in the JT file.

   • Write B-Rep Data: By default, the exporter writes only the Visualization model (Viz-Rep) for speed and typical user needs. Enabling this option includes the true CAD geometry (B-Rep) in the JT file.

   • JT Version Number: Default version is 9.0, compatible with the largest user group. Versions 6.4 through 10.5 are supported.

   • JT Faceting Options: Applicable only to Viz-Rep JT files. For B-Rep JT files, the plugin uses the JT Open recommended option “JtkSMART_LODS”, which creates multiple Levels of Detail (LODs) based on B-Rep data. Faceting options are ignored for B-Rep files, as importing applications generate the mesh automatically.

   • Reset Defaults: Restore all JT export settings to their default values.
