AutoCAD and Its Applications—Advanced
Move, Rotate, and Scale Objects in 3D Space
The
ALIGN
command has the same functions of the
3DALIGN
command, but adds
the ability to scale an object. See Figure 8-7. The 90° 7 7 bend must be rotated and scaled to
fi t onto the end of the HVAC assembly. Two source points and two destination points fi
are required, Figure 8-7A. Then, you can choose to scale the object.
Select objects:

Specify first destination point:
(pick P2; a line is drawn between the two points)
Specify second source point:
(pick P3)
Specify second destination point:
(pick P4; a line is drawn between the two points)
Specify third source point or continue: ↵
Scale objects based on alignment points? [Yes/No] N: Y↵ Y Y
The 90° bend is aligned and uniformly scaled to meet the existing ductwork object.
See Figure 8-7B. You can also align using three source and three destination points.
However, when doing so, you cannot scale the object.

Notice how the bend
is not at the proper
