ALIGN

Moves and rotates objects to align with other objects.

Specify:

1 Select objects
2 Specify 1st source point [1]
3 Specify 1st destination point [2]
4 Specify 2nd source point [3]
5 Specify 2nd destination point [4]
6 Specify 3rd source point [5] (and 3d destination point [6]) or continue <continue>
7 Scale object to alignment points? [yes/no] <N> (for two pairs of points only)

You can specify up to three pairs of points for alignment. The first set of source and destination points defines the base point for the alignment. The second pair defines the angle of rotation; the source object (points 1,3) is aligned with the destination object (2,4). A third pair rotates the source object again (3,5) so that the source object aligns with the destination object (4,6).
