We have constructed the door opening in 3D Studio MAX ( 3ds max ). Now let's create the actual door. In the left viewport you'll be able to see the outline of the hole created for the door.

Create a box by drawing it in the left viewport covering the entire hole. Refer the figure. Change the size of the box as follows: length: 150, width: 100, height: 5. Position the box in the left viewport so that it covers the hole completely.

In the top viewport, move the door to the right end, so that it overlaps with the door's hole on the wall.

Now the door is in a closed state. In order to make it opened, we need to rotate it. But if you try to rotate the door using the rotate tool, you will notice that the door rotates with a pivot point not at the hinge, but at the centre. By default in 3D Studio MAX ( 3ds max ), objects will have their pivot points at their centre. Here, we need to move the pivot point of the door to its hinge. To do that follow the steps:

With the door selected, Click on the Hierarchy tab which is adjacent to the create tab in 3D Studio MAX ( 3ds max ). In the hierarchy panel, make sure that the Pivot button is depressed, near the top. Click on the Affect Pivot Only button to make it active in 3D Studio MAX ( 3ds max ). Now, what you move in the viewports will be the pivot point of the door, instead of the door itself. Using the move tool, move the pivot of the door to its hinge in the left viewport. See the figure. After aligning the Pivot, click again on the Affect Pivot Only button to deactivate it in 3D Studio MAX ( 3ds max ).

In the Top viewport, using the Rotate tool, rotate the door so that it is in an opened position as shown in the figure.
