Orbit Tool
You use the Orbit tool to change the orientation of a model. The cursor changes to the Orbit cursor. As you drag
the cursor, the model rotates around a pivot point while the view remains fixed.
Specify the Pivot Point
The pivot point is the base point used when rotating the model with the Orbit tool. You can specify the pivot
point in the following ways:
Default pivot point. When you first open a model, the target point of the current view is used as the pivot
point for orbiting the model.
Select objects. You can select objects before the Orbit tool is used to calculate the pivot point. The pivot
point is calculated based on the center of the extents of the selected objects.
Center tool. You can specify a point on the model to use as the pivot point for orbiting with the Center tool.
CTRL+Click and drag. Press and hold down the CTRL key before clicking the Orbit wedge or while the Orbit
tool is active; then drag to the point on the model you want to use as the pivot point. This option is only
available when using the big and mini Full Navigation wheels or the mini View Object wheel.
NOTE While the Orbit tool is active, you can press and hold the CTRL key at anytime to move the pivot point used
by the Orbit tool.This pivot point is used for subsequent navigation until it is moved.
Maintain Up Direction
You can control how the model orbits around the pivot point by choosing to maintain the up direction of the
model. When the up direction is maintained, orbiting is constrained along the XY axis and in the Z direction. If
