CAD tip # 13694:

But using add-on applications you can still perform some editing operations on elements of rectangular, polar and curve arrays in AutoCAD while not losing their dynamic functionality.

Examples are the utilities HideItem (hide selected elements), TrimArr (trim the array to the boundary), or Scatter (randomly recolor, nudge, rotate, or scale elements). In the case of Scatter, the individual modifications of nudge/move, rotate, or scale are lost when the span of the rows/columns of the array is subsequently changed. All newly added array elements (e.g. columns) will have the default properties.

To recolor elements in Scatter, it is important to set the default color of the source array element to ByBlock . Recoloring is typically used for tile patterns and layouts, pavings, facades, or other decorations. Both HideItem and Scatter can be used also in AutoCAD LT (2024 and above).
