I am grateful that you took time to install TAD.
I would be more grateful if you can make a donation for this project.

TAD gets updated very regularly. Once you start TAD, go to the Help menu; and check for updates. We also update the “Tips” that are presented to you when you start the software. Read them! Get into the habit of clicking the Fetch button of the Tips Dialog. You will get additional tips once a while from our server.

If you have just updated an earlier version of TAD
You should read the history of changes here.

… and of course, you should go thru the extensive documentation at this site you are reading now. It even has links to videos made on TAD

Please note:
TAD is not really meant for amateurs and hobbyists. It is meant for trained architects, students of architecture and researchers in the field.
