PDF allows the user to export PDF files from a selected Revit® model, while also allowing the user to select the model print sets to be exported. The user can combine the selection into a single pdf and specify the location for the file to be saved. Each model will have it's own folder created in the export folder location.

When editing is complete, press Save or Cancel. These settings can be modified at any time prior to deploying the job. Once the job has been deployed, however, they cannot be changed. To change the settings, the job will first need to be un-deployed; the settings changed and saved; then the job can be redeployed.
