Transforming with the Bounding-Box Manipulator

As an alternative to using the transformation tools, you can use the bounding box manipulator to scale, rotate, and translate objects. The bounding-box manipulator has a set of handles that let you interactively manipulate objects in the 3D views.

 

Bounding box manipulators do not work well in the Object view unless you deactivate View > Camera Compensation.

To activate the bounding-box manipulator

1. Select the object.

2. Press b or choose Manipulate Tool from the eye icon menu on a viewport.

3. Press the Tab key to alternate between the two types of manipulator handles, each of which let you perform different types of operations (see the illustration below).

 

Mode 1: Scaling

Position the mouse pointer over one of the manipulator’s corners:

• To scale uniformly about the object’s center, click a corner and drag.

• To scale non-uniformly relative to the opposite corner, Shift+click and drag.

• To scale uniformly relative to the opposite corner, Ctrl+click and drag.

Mode 1: Rotating

Position the mouse pointer over one of the manipulator’s edges:

• To rotate about an axis parallel to the picked edge passing through the object’s center, click an edge and drag.

• Press the Shift key to rotate relative to the opposite edge.

• Press the Ctrl key to rotate the edge freely.

Mode 1: Translating

Position the mouse pointer over one of the manipulator’s sides:

• To translate in any direction along the plane, click the plane and drag.

• To translate along the picked plane’s normals, Shift+click and drag.

• To translate freely in any direction, Ctrl+click and drag.

Mode 2: Rotating

• Drag the arrow manipulator to rotate the object freely along its three axes.
