thank you very much for the proposal @maxim_k !

it's urgent as everything! I guess.

I'd be super glad to have this in some ways, soon or later (maybe not too late though).

by now, I've managed to install a win version (on parallel, so it's quite slow), and used a vlisp that helps selecting objects within plines. the problem with this script is that it also selects islands and their content within the plines. so it's sometimes quite some work for checking and correct all issues. but most of all, that would be so much easier and efficient if there could be a way to work directly on mac.

about the detail: I need to be able to select circles that have their center within the hatch (in order to move them to a different layer). maybe I could work first with dots, if it's too complex to consider the center of the circle, and in a further time, replace dots by circles. but the easiest would be being able to work with circles directly.

and attached is a file which my be used as en example.

anyway, thank you very much for your help.
