The ARRAY command creates copies of objects in a rectangular or polar (circular) pattern called an array.
In AutoCAD MEP 2024 toolset, you can use ARRAY to create arrays of a selection set of objects (for example, a complete duct branch). If possible, the software connects a suitable object in each copy of the selection set, such as a tee or takeoff, to a segment at each destination.
Unlike COPY or MOVE, ARRAY does not align or orient the copies of the selection set when it connects them to objects at their destinations. The copies maintain the alignment and orientation of the original selection set.
