Move and Rotate Objects in 3D Space
The basic operation of moving and rotating an object relative to a second object or
set of points is done with the
3DALIGN
command. It allows you to reorient an object in
3D space. Using this command, you can correct errors of 3D construction and quickly
manipulate 3D objects. The
3DALIGN
command requires existing points (source) and
the new location of those existing points (destination).
For example, refer to Figure 8-5. The wedge in Figure 8-5A is aligned in its new
position in Figure 8-5B as follows. Set the
Intersection
or
Endpoint
running object
snap to make point selection easier. Refer to the fi gure for the pick points.
