The revolving door seems lonely, spinning by itself in the viewport. You can use the Merge command to put this revolving door into context, by merging in a scene of an entranceway.
You'll also learn to animate the opening of parametric doors.
Set up the lesson:
Merge a scene:
After you click the file name, the Merge File dialog displays a thumbnail of the scene.
If the Duplicate Name dialog appears, click Skip for any duplicate objects.
The revolving door is now in the middle of the entranceway.
Animate the double doors:
The spinner arrows are now outlined in red, indicating that Open is an animated parameter that has a key on the current frame.
The revolving doors go around and the double doors swing open.
Fine-tune the animation:
You can use the track bar to make the double doors open and close faster.
The doors open and close more quickly.
You can make the doors open and close repeatedly throughout the animation by using Track View.
A Track View - Curve Editor window opens with the Double doors Open parameter highlighted.
If you don't see this button, then right-click a blank area of the Track View toolbar, and from the pop-up menu choose Show Toolbars Curves: Track View.
The Curve Editor now shows how the animation will repeat.
Now the doors open and shut throughout the animation.
Save your work:

In this tutorial you learned to find your way around the 3ds Max user interface and to do some simple modeling and animation. You learned to work with primitive objects and apply and edit materials. You created a door object, made clones of it, and linked the doors to a parent object in order to make an animation. Lastly, you learned to merge files together to create a more complex scene.
