448 Chapter 6: Transforms: Moving, Rotating, and Scaling Objects
You can align the position and orientation of the
bounding box (page 3–1013) of the source object
to the bounding box of a target object.
You can use the Align tool with any selection that
canbetransformed.Ifanaxistripodisdisplayed,
you can align the tripod (and the geometr y it
represents) to any other object in the scene.
When performing sub-object alignment, the
Current Object options and the Match Scale check
boxes are disabled. If you plan to alig n orientation
for sub-objects, first switch to Local transform
mode on the Main toolbar so that the axis tripod is
properly aligned with your sub-object selection.
