ClassDraw Video Demo
For the best introduction to using ClassDraw, sit back and watch the online demo. The demo lasts about 5 minutes and shows you how to create a class diagram and make various adjustments to it. You can control the movie using the control bar at the bottom of the screen.
For best results, your display should be set to a resolution of at least 1024 x 768 pixels. If your resolution is lower than that, you will not be able to see everything without scrolling.
If the demo does not occupy the full screen when it appears, you should to press the F11 key.
