In this paper is presented the 3D model of Chua's circuit boundary surfaces. This represents the boundary between the two attractors - chaos and a stable limit cycle. In the first part is described short history of Chua's circuit and sequential circuits boundary surface modelling and visualization. Second part describes 3D modeling of boundary surface. Three dimensional model of boundary surface is created by appropriate combination lot of 2D cross-sections in surface u1=const using triangulation. The modelling and visualization of boundary surface represents modelling and visualization of large graphical data set and is timeconsuming process.
