Convert Existing UML Project in SVN to Teamwork Project
Currently the SVN integration do not support directly checkout existing vpp file as the teamwork project. To convert your existing UML project (*.vpp) in your SVN server into teamwork project:
Export the UML project from repository to your local disk.
Remove the project from your SVN repository (to prevent mistakes in checking our invalid project).
Open VP-UML and login to SVN server.
Press the
Import button in Teamwork Cleint.
Select Import existing project and press the ... button to select the file exported in step 1.
Specify the location for storing the teamwork project. You can right click on the repository tree to create new remote folder.

After that you can checkout the project from server and commit your changes back.
