Is it possible to write a LISP that allows objects from one hatch to be made islands for another hatch?

[edushka228]

The task is to create the visibility of hatches overlapping each other. For example, we have two hatches: first add the first hatch, then add the second hatch so that the objects of the first hatch become islands for the second hatch. If we add a third hatch, it will look like it is located under the two previous hatches

I've read what you wrote and I think it's possible with my last HHB.lsp (not HHB-new.lsp)... HHB.lsp creates wipeouts from picked hatch... If there were other hatches it masks lower ones... You should be able to apply it several times like you described in link you provided...
