This program is an Autolisp routine that allows copying the selection further with each mouse click or by pressing the Enter button. The copies are made with equal distance as the first instance. Information about each copy is displayed in the command line. To quit the function press ESC. Sometimes you needed to copy objects with equal distance from original place 400-800-1200mm and so on but some numbers or bigger values when summing aren't easy to calculate, so Lisp makes this easy for the user.
To learn how to use it, read the General Usage Instructions and see a video-example. Free trial version available to download at www.autolisps.blogspot.com
