It would be very helpful to be able to limit which sets of objects are allowed to interact. For example, being able to tell a window that it’s allow to cut one set of walls but not another. This would make it possible to show different stages of a project in one file or to show several different design options at once. Currently you’d need to keep models synced across several files, which while possible isn’t ideal.
Thank you for developing such a wonderful tool and being active in the community supporting it!
