Aligning Objects in 3D Aligning Objects in 3D
AutoCAD provides two different methods with which to move and rotate objects
in a single command. This is called aligning objects. The simplest method is to align
3D objects by picking source points on the fi rst object and then picking destination
points on the object to which the fi rst one is to be aligned. This is accomplished with
the
3DALIGN
command, which allows you to both relocate and rotate the object. The
second method is possible with the
ALIGN
command. The
ALIGN
command aligns
2D or 3D objects according to three sets of alignment pairs. You fi rst select the source
object, then the fi rst source point, and fi nally the fi rst destination point on the destina-
tion object. This technique is repeated two more times to align one object to another.
This method of aligning allows you to not only move and rotate an object, but scale
the object being aligned.
