You can resize objects
to make them longer or shorter in only one direction or to make
them proportionally larger or smaller.
You
can also stretch certain objects by moving an endpoint, vertex,
or control point.
Lengthen Objects
With LENGTHEN, you can change
the included angle of arcs and the length of the following objects:
- Lines
- Arcs
- Open polylines
- Elliptical arcs
- Open splines.
The results are similar to extending and trimming.
You can
- Drag an object endpoint dynamically
- Specify a new length or angle as a percentage
of the total length or angle
- Specify an incremental length or angle
measured from an endpoint
- Specify the object's total absolute length
or included angle
Stretch Objects
With
STRETCH, you relocate the endpoints of objects that lie across or within
a crossing selection window.
- Objects that are partially enclosed by
a crossing window are stretched.
- Objects that are completely enclosed
within the crossing window, or that are selected individually, are
moved rather than stretched.
To stretch an object, you specify a base point
and then a point of displacement.
To stretch with precision, use object snaps,
grid snaps, and relative coordinate entry.
Scale Objects Using a Scale
Factor
With SCALE, you can make
an object uniformly larger or smaller. To scale an object, you specify
a base point and a scale factor. Alternatively, you can specify
a length to be used as a scale factor based on the current drawing units.
A scale factor greater than 1 enlarges the object.
A scale factor between 0 and 1 shrinks 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.
NoteWhen you use the
SCALE command with
annotative objects,
the position or location of the object is scaled relative to the
base point of the scale operation, but the size of the object is
not changed.
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
- Select the object using a crossing window
selection.
The crossing window must
include at least one vertex or endpoint.
- 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
-
- Select the object to scale.
- Specify the base point.
- Enter the scale factor or drag and click
to specify a new scale.
To scale an object by reference
- Select the object to scale.
- Select the base point.
- Enter r (Reference).
- Select the first and second reference
points, or enter a value for the reference length.
To change the length of
an object by dragging
- Enter dy (Dynamic
Dragging mode).
- Select the object you want to lengthen.
- Drag the endpoint closest to the point
of selection, and specify a new endpoint.
The selected object is lengthened or shortened
without changing its location or orientation.
