Step 2: Install...

Once downloaded select the option to ‘Open’ or run the file (if this option is not presented simply run the executable from the temporary location you chose).

Follow the typical installation dialogs through to the finish. A shortcut to the Tas Manager should have appeared on the desktop.


Step 3: Register...

Double click the shortcut to start the Tas Manager. Click the ‘Register’ button to bring up the registration dialog. Double click anywhere in the ID box to highlight the ID, then right click and select the ‘Copy’ option (or use Ctrl + C) to copy the Tas Manager ID.

Click here to go to the Demo Key Request page and follow the on screen instructions.

If your request is successful, you will receive an Email containing keys that will license the software for 4 weeks. Once you have received the Email, paste the keys into the register dialog and click OK.

The software is now ready to use.


Step 4: Getting Started...

There are detailed tutorials for each aspect of the software. You can find these by clicking on 'Tutorials' in the left pane of Tas Manager, or at our Documentation page. These tutorials are updated with every new release of Tas.

After studying the tutorials you can create a new project by selecting ‘Tas Data’ in the left pane of Tas Manager, then clicking the ‘Create Project’ button. Enter a name for the new project and click ‘OK’. Make this project the current project by first clicking on it, then right clicking and selecting ‘Set Current Directory…’. Next, to make a building in this project, click the ‘Create Building’ button. This will start the 3D Modeller and the steps of the tutorial can be followed. (Note: due to the behaviour of Windows 2000 and XP when you ‘Save As..’ or ‘Save’ your new file you may need to navigate to the current project as the default behaviour in these systems is to always remember the last location a file was saved by the current application).

Once a file has been created you can access it directly by selecting the project in the left pane of the Tas Manager and then double clicking the file in the right pane.

By default UK weather data is included with the Tas demo. Click here to download weather data for different regions.
