problem with bolean operations

[Pinuzzo Designer]

Bye to all,
someone of you knows why when to gate (from the tree) an operation
Does boleana also erase me the added solid?
example: I add (operation add..) a cylinder to a cube if I later want to delete the add operation also deletes the cylinder.
Thank you for your help!

When you delete the "add" function, for example, a finsertra opens. in that window you must uncheck the option "delete aggregated items".

Yes, that window appears. Plus I went to change the parameters
in tools-->option-infrastructure --part> infrastructure--> and disabled
Hybrid design.:smile:
Thank you!
