You can submit an SI/SSI to TNA from within Lawmaker.
The submission process is not yet fully automated, so there are some additional steps you need to follow to submit your SI/SSI.
How to submit to TNA
From the Project Tab, generate a PDF of the working version that you wish to submit to TNA.
Find the PDF snapshot and select Actions > Submit to TNA.
Click Submit in the dialog box that appears. A significant version will appear on the right of your screen.
On the significant version, select Actions > Download ZIP file.
Click Download in the dialog box that appears. A zip file will be created containing the PDF and XML file, and also any images included in your SI/SSI.
You can now use this zip file to upload into TNA’s publishing system.
