Scale Objects Using a Reference Distance
You can also scale by reference. Scaling by reference uses an existing distance
as a basis for the new size. To scale by reference, specify the current distance
and then the new desired size. For example, if one side of an object is 4.8 units
long and you want to expand it to 7.5 units, use 4.8 as the reference length.
You can use the Reference option to scale an entire drawing. For example, use
this option when the original drawing units need to be changed. Select all
objects in the drawing. Then use Reference to select two points and specify
the intended distance. All the objects in the drawing are scaled accordingly.

To stretch an object
1 Click Home tab ➤ Modify panel ➤ Stretch.
2 Select the object using a crossing window selection.
The crossing window must include at least one vertex or endpoint.
3 Do one of the following:
■ Enter the displacement in the form of a relative Cartesian, polar,
cylindrical, or spherical coordinate. Do not include the @ sign, because
a relative coordinate is assumed. Press Enter at the prompt for the
second point of displacement.
■ Specify the base point for the stretch, and then specify a second point,
to determine the distance and direction.
Any objects with at least one vertex or endpoint included within the
crossing window are stretched. Any objects that are completely within
the crossing window, or selected individually, are moved without
stretching.
To scale an object by a scale factor
1 Click Home tab ➤ Modify panel ➤ Scale.
