Say I have a very simple object (e.g. a house) that consist out of the roof and the walls. How do I actually model this relationship using Blender? With CTRL+P I can either make roof or the walls the parent of the respective other object. But neither roof nor walls actually, logically, should be the parent but a new object called "house". "House" so to say should consist out of the union of roof and walls, but Blender should still be aware of the separate children objects.
Is this comprehensible?
