This simulator is expected to help surgeons improve surgical planning and practicing surgery done with 3D models. The simulation result can be evaluated before surgery performed on actual patients. This will help surgeons to obtain a clear picture of the result of surgery. If the surgeon found a few mistakes, he will able to fix it with a repeat surgical procedure many time until it produces the end result, according to the results that meet the standard surgical procedure. Simulator that successfully constructed to give an idea associated with problems biomodeling heartbeat, tool movement, cutting, and bleeding. The four topics are the basis on making CABbaGe simulator, which can be furthher enchanced its development with various features and interfaces of interest. Keywords: biomodeling heartbeat, tool movement, cutting, bleeding.
