Re: NegativeAllow the elevation of the object to be negative!
You can always create a "middle" level called for example (railing or floor-divider) whose have a lower elevation than the upper floor, so you can add things there at your desired elevation

Adding more unnecessary floors will make things more complicated and less convenient to understand.Beginners may be totally confused.

But if the height of the object can be negative. It's all simple and efficient.
