Scaling Entities

Use the Scale command to enlarge or reduce entities while keeping proportions the same.

To scale entities:

1. Click Modify > Scale (or type Scale).
2. In the graphics area, select entities to scale.
3. Press Enter.
4. Specify the base point.

   The base point, if part of the specified entities, holds its original position during scaling, while all other points move by the same relative values in the direction of the X-, Y-, and optional Z-axis. For the base point, you can instead select a point not on an existing entity. In this case, the distance from the base point to all other points making up the entity change by the same scale factor.

5. Enter the scale factor or specify the Reference option to enter a reference length and a new length. Optionally, specify the Points option to represent the reference length as two points.

   A scaling factor larger than 1 enlarges the entities by this factor. A scaling factor between 0 and 1 reduces the entities by this factor. For instance, the factor 3 enlarges the selected entities three times, while the factor 0.25 reduces the entities to a quarter of their original size.

   Use Reference to specify an exact change in the lengths of entities. For example, to enlarge an entity with a side length of 3.45 drawing units up to 3.54, you have to calculate the scaling factor. With Reference, however, you specify the reference length (3.45) and the new length (3.54).
