What is the purpose of the "SCALE" command in AutoCAD?

The purpose of the "SCALE" command in AutoCAD is to resize objects proportionally, meaning that it can increase or decrease the size of an object while maintaining its original proportions. This is particularly useful when you need to adjust the dimensions of an object to fit a certain design requirement without altering its shape.

When you use the SCALE command, you are prompted to specify a base point and a scale factor. The base point is the reference point about which the object is scaled, and the scale factor indicates how much larger or smaller you want the object to be. For example, a scale factor of 2 doubles the size, while a scale factor of 0.5 reduces it by half. This command is essential in drafting and design as it allows for accurate modifications of drawings without distorting the objects involved.

In contrast, the other options describe functions that do not relate to resizing objects. Changing the color of objects pertains to appearance modifications, aligning objects involves positioning them relative to one another, and grouping objects relates to managing multiple entities for easier manipulation.
