HELP???? me determine how the series of copy and rotate

Could anyone HELP me determine how the series of copy and rotate items have been created?

This is my scenario. The old cad system that being used is an old school dos system that was personally customized to suit our requirement. There are macros that have been created within this old programme to create company specific geometry. I have been going through the process of re-creating the macros and adding them to AutoCAD so I only have to use AutoCAD. The problem is one of the macros create what look like a series of copy and rotate on one object. I have been trying to work out how it generates this with no success. I would gratefully appreciate it if anyone could shed some light on how it is created so i then can write a lisp file to suit

I have attached dwg. File so you can view the geometry.

Thanks
