An array is a fundamental data structure in computer programming, used to store a collection of elements of the same type. It provides a way to organize and access data efficiently. In an array, elements are stored sequentially in contiguous memory locations, and each element is identified by its index or position within the array, with key characteristics like;
Homogeneity
Fixed Size
Random Access

In AutoCAD, an “array” refers to a set of objects that are arranged in a pattern or sequence. AutoCAD provides several tools and commands for creating arrays of objects, allowing users to efficiently replicate and distribute elements within a drawing.
Rectangular Array
Polar Array
Path Array
Associative Arrays
To create an array in AutoCAD, users typically use the “Array” command or one of its variants (e.g., “RectangularArray,” “PolarArray”). These commands provide options for specifying the type of array, selecting the objects to be arrayed, and defining the array parameters such as spacing, orientation, and number of items.
