Chapter 24. XTRA TOOLS > Using the 3D Rotation Tool

Using the 3D Rotation Tool

The 3D Rotation tool applies a combination of transformations to an object as if it were rotated in space. Before you use the 3D Rotation tool, you must set its controls.

To set the 3D Rotation controls:

1.
Double-click the 3D Rotation tool in the Xtra tools toolbar 1. The 3D Rotation controls appears 2.

Figure 2. The 3D Rotation controls in the Easy mode (left) and Expert mode (right).


2.
Use the Rotate from menu to select the point from which the rotation should occur as follows:

  • Mouse click sets the rotation pivot point to the position where you click.

  • Center of selection makes the point the physical center of the object.

  • Center of gravity sets the rotation pivot point to the center of the object when adjusted for uneven shapes.

  • Origin sets the rotation pivot point to the bottom-left corner of the bounding box that surrounds the selection.

3.
Set a Distance amount for how much distortion occurs during the rotation. For the greatest distortion effect, enter small numbers.

4.
In the Expert mode, use the Project from menu to select the projection point (the perspective vanishing point) as follows:

  • Mouse click sets the rotation pivot point to the position where you click.

  • Center of selection makes the point the physical center of the object.

  • Center of gravity sets the rotation pivot point to the center of the object when adjusted for uneven shapes.

  • Origin sets the rotation pivot point to the bottom-left corner of the bounding box that surrounds the selection.

  • X/Y coordinates sets the projection points from coordinates you enter in the fields.
