Modifying entities - Resizing entities

Scaling entities

You can change the size of a selected entity by scaling it in relation to a base point. You can change the size of an entity by specifying a base point and a length, which is used as a scale factor based on the current drawing units, or by specifying a scale factor. You can also use a scale factor referenced to a base scale factor, for example, by specifying the current length and a new length for the entity.

To scale a selection set by a scale factor
  1. Do one of the following:
  2. Choose Modify > Scale.
  3. On the Modify toolbar, click the Scale tool (
  4. ).
  • Type scale and then press Enter.
  • Select the entities, and then press Enter.
  • Specify the base point.
  • Specify the scale factor.



    To scale an entity by a scale factor, select the entity ( A ),
    and then specify the base point ( B ) and the scale factor.



  • You can also scale some entities using grips. To scale an entity, you select the entity, and then click a grip. You then change the size of the entity by moving the grip. The grip you select depends on the type of entity you're modifying. For example, to scale a circle, select a quadrant point grip.
To scale an entity using grips
  1. Select the entity.
  2. Click a grip to select it.
  3. Drag the grip.
  4. Click to release.



    To scale using grips, select the entity ( A ), click a grip ( B ), and scale the entity by dragging the grip to its new
    location ( C ).
