Interactive models are made for the purpose of communicating complex messages smoothly to the audiences. The interactivity levels can be controlled by lights and sounds. These features are controlled by switches ranging from regular buttons to latest full touchscreen interfaces. A switch console activates lights at required zones with on-screen information.

In the case of masterplan models touchscreens and lighting programming may be used to highlight apartment types or different phases of the development while at the same time displaying animations, renderings and information about the project on the touchscreen.

In case of industrial models, the process flow is demonstrated using LED lightings and similar coloured liquids, which has a central console unit having labelled buttons. The efficiency of large projects like power generating grids can be described using its replica models.
