lisp to order cnc machining

[Nicola94cad]

Good morning, everyone.

autocad use to create programs for my cnc machine.

I create a dxf file containing tool paths, then the machine converts it to g-code.

the machine takes the order of the processing according to the order in which the entities were drawn, so, if I have to change the order of the processing, I have to create a copy of the entities and then copy them one by one in the order I want (and then I delete the paths drawn previously).

As it is a long enough operation to do, my idea is a lisp that orders the processing just asking to select the processing in the correct order.

I tried it and it works very well! thank you!
The only thing that worries me is that if entities are overlapped, they select both.
Can you fix it?

only the "over" object is selected
