Stretch Objects
To stretch an object, you specify a base point and then a point of displace-
ment. Because stretching moves the endpoints that lie within the crossing
selection window, you must select the object with a crossing selection. To
stretch with greater accuracy, you can combine grip editing with object
snaps, grid snaps, and relative coordinate entry.
Scale Objects
With scaling you can make an object larger or smaller, but you cannot alter
its proportions. You can scale it by specifying a base point and a length,
which is used as a scale factor based on the current drawing units, or by enter-
ing a scale factor. You can also specify the current length and a new length
for the object.
Scaling changes the size of all dimensions of the selected object. A scale factor
greater than 1 enlarges the object. A scale factor less than 1 shrinks the
object.
You can also scale by reference. Scaling by reference uses an existing measure-
ment as a basis for the new size. To scale by reference, specify the current
measurement 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.
