ProtoTech Solutions and Services Pvt. Ltd
JT Exporter for Autodesk® AutoCAD® exports the AutoCAD drawing into JT file format.

General Usage Instructions

  1. Download and install the app.
  2. Run AutoCAD and Load a model.
  3. There’s an ‘Add-ins’ tab on the ribbon bar. It contains the following ribbon buttons as shown in the image below: ‘Export', ‘Preference’, and 'About Us'.
  4. Click on the ‘Export’ button to export the model to the .jt file.
  5. This will launch save as a dialog in which you can specify the directory and filename of your choice.
  6. From preferences, you can set the options for the output file. The options are as follows:-
    • Write Out Point Bodies (Points) - By default, points are not exported to JT. Check this to write out points.
    • Write B-Rep Data - The typical JT file will contain only the Visualization model (Viz-Rep); however, the JT format also supports the storage of true CAD geometry (B-Rep). By default, we write the Viz-Rep version of the model as this is extremely fast and is also what the typical user is looking for. Checking the "Write B-Rep Data" will instruct the plugin to include the B-Rep data in the JT file.
    • JT Version Number - By default, we write out JT version 9.0 to address the largest group of current users. However, JT versions 6.4 through 10.5 are supported.
    • JT Faceting Options: Please note that ANY faceting option listed here is relative to Visualization Representation (V-Rep) JT files ONLY.  For JT files with B-Reps we use the JT Open recommended option "JtkSMART_LODS" in our translator, which automatically creates several LODs based on the B-Rep data. With B-Rep JT files, it is presumed that the applications importing them will use the B-Rep data to generate a faceted mesh on the importing application side and thus faceting options are irrelevant.
    • Reset Defaults - Click this button to reset to default settings for JT.

        7. The 'About Us' button displays information about the company, product, and license details.
