What is the function of the "ARRAY" command in AutoCAD?

The "ARRAY" command in AutoCAD is designed to create multiple copies of selected objects arranged in a specified pattern, such as a rectangular grid, circular arrangement, or along a path. This functionality is essential for tasks where repetitive design elements are needed, allowing users to efficiently populate an area with identical objects without having to manually copy and place each one individually.

For example, if you were designing a column layout in a building, using the ARRAY command would enable you to quickly replicate a single column's design at regular intervals, ensuring uniformity and saving considerable time in the drafting process. The command simplifies workflows, enhances precision in spacing, and improves overall productivity in design tasks.

In contrast, the other choices refer to different functions: combining shapes, replacing objects, or measuring distances, none of which pertain to the primary function of the ARRAY command.
