Electronic panel system, an arrangement and methods for providing enriched visualization possibilities and user-controlled interaction experience with life-size and real-looking 3D models of real objects are provided. The arrangement comprising a virtual product assistant sub-system and the electronic panel system facilitates receiving real-time product information related to current state of 3D model representing real object displayed on the electronic panel system. Advanced user-controlled interactions with the displayed 3D model is made possible to perform deletion interaction, addition interaction, immersive interactions, linked movement interactions, interaction for getting un-interrupted view of internal parts using transparency-opacity effect, inter-interactions, liquid and fumes flow interactions, extrusive and intrusive interactions, time bound changes based interactions, environment mapping based interactions and engineering disintegration interactions with the displayed 3D model. The 3D model displayed is preferably a life-size 3D model, which can be further zoomed to view detailing without any blurring.
