The task of a simulator is to make it possible to inspect the structures of the virtual house only with the help of the Internet and available gadgets, without additional accessories or a licensed program.

All the simulators are Internet websites that quickly open and function at the user's choice. 

To create a simulator, computer programs REVIT and AutoCAD for modelling by drawings,  Griffel Studio glTF Exporter, and Phyton for programming are used.
