Trimble Quadri Help
Sometimes, Trimble Support will suggest that you redefine your Quadri Connection. A Quadri Connection is the definition of settings specified in the "Join Project" dialog, to allow you to see the models on a specific server.
To redefine a Quadri Connection:
Go to the "Join Project" dialog.
Click on the existing connection for the server.
Press the button with a red cross and confirm that you want to delete this.
Click the button with a green plus sign and enter the credentials for the server.
Restart Quadri for Windows.
