Sign In

First, you’ll need to log in to your EC3 account. Either click the Sign in… button in the Tally Climate Action Tool (tallyCAT) ribbon, or go to EC3 Analysis > Sign in…

Please note that the plugin requires WebView 2 from Microsoft installed. If it’s not present on your PC, the following dialog will pop up.

Click Download & Install to automatically install missing components to your system. After the installation finishes, restart Revit.

If you already have WebView 2, the plugin will start the login process.

Starting from the Tally Climate Action Tool (tallyCAT) v0.10, the plugin uses the OAuth2 authentication. This means that the plugin will use your default system browser for performing the login and then store your login credentials between Revit sessions, so you’ll no longer need to sign in on every Revit start.

Upon clicking the Sign in button, the plugin will open your default system browser with the login form. Also, a progress dialog will be shown through the whole process of signing in, so you may cancel the login at any moment by either closing it or clicking the Cancel button.

You may either sign in by entering your login and password or use Google, Microsoft or LinkedIn login options.

After signing in through the form, you’ll need to give the Tally Climate Action Tool (tallyCAT) the required permissions by clicking the Allow button.

If everything went fine, the browser will display the following page and the progress dialog will close automatically.

Now, you can close the page in the browser and switch back to the Revit window where the EC3 ribbon should change.

• The ribbon Sign in… button changed its icon and now shows the user's login. If you click it, you will be signed out after a prompt.
• Under the EC3 Analysis drop-down menu, the Sign in… command became Sign out and also changed the icon. If you click it, you will be signed out after a prompt.
• If the current Revit project doesn’t have a 3D view called tallyCAT, the drop-down menu will show a command that creates one. This view will be used later for all the operations performed by Tally Climate Action Tool (tallyCAT).
• If the tallyCAT view is already created, the ribbon will show additional commands: Export to EC3, Open in EC3, Manage Scope, Detach from EC3, Properties & charts and Export to JSON. Depending on whether the project was exported to EC3 or not, certain options will be enabled or disabled.
• You could click Export to EC3 to start the export process instantly with the default settings, or you could go to Manage Scope to configure what’s exported first.

• If you exit Revit and start it again, you’ll remain signed in.
