That is not possible.
Firstly, you cannot patent an idea. A transport means that goes up and down (an elevator) is just a concept and cannot be patented. You can only patent implementation of the idea. In the case of an elevator, the claims are certain to specify certain physical elements required to implement the system.
Secondly, for a patent to be valid, it must be "useful". A visual control system is only useful if the visualization is a representation of a physical system actually working.
Even in the case someone files a patent with claims so broad that it encompasses both physical and virtual elevators, and in the extremely unlikely case that the patent get granted, it would be easy the challenge the validity of the patent and have the court limit the claims to something more meaningful.
The only time you will get into trouble is that the patent is itself a software patent, for example, a patent specifically on elevator simulation. A good test for that is ask yourself this question: "do you think that your visual control system is patent-able?"
