The A4D file has been superceded by the 4DV file. Although the newer 4DIM players will play A4D files the newer 4DV files are more feature rich and flexible. The author of 4DIM files is encouraged to take advantage of the ability to bundle any number of 4DV files into their 4DIMs and minimize the burden on the end-consumer (user) of the 4DIMs.
The best way to appreciate the power of bundled scripts is to play one. Several preset views and animation script files that work with most all 4DIM files are built into the Standard 4DIM Script library. To access them, from the 4D Interactive Model Player window, choose the File pull-down menu and select Choose 4DIM View. On this window there is a radio selector to choose between Standard Library and Bundled Views and Scripts. All 4DIM files will have access to the Standard Library, whereas Bundled scripts are only available if they are created and bundled by the 4DIM author.
Select Standard Library and chose Fancy Rotation.
Unfortunately it isn't possible to show you in the help what happens, but what you should see is an animation that begins with a TOP view, rotates down to 20 degree elevation, spins around 360 degrees and then returns to the top view.
A4D Files: This help discussion is still included for backwards compatibility.
From the 4D Interactive Model Player window, choose the File pull-down menu and select Choose 4DIM View. On this window there is a button in the lower right to Play .A4D File. Browse to the .a4d file to select it. If the .a4d file is an older style fly through, once it finishes it leaves the Viewer in a non-standard mode. Attempts to interact with the model will give unexpected results. To reset the Viewer after playing an A4D file, choose Reset After A4D Fly-Through on the RNC pull-down menu.
Note: If you have a Multimedia keyboard with Play/Pause and Stop buttons, these will control the 4DIM player during script playback the same as the buttons at the bottom of the player.
