Hi Frederick,

It depends on the object type - on a group setting group.hidden = true will set hidden = true on the immediate children of the group.

On other objects no - on a solid for example setting solid_obj.hidden = true does not set .hidden = true on all of its face and edge sub-objects.

A sub object is effectively hidden if either it or any of its parent objects has hidden == true.
