The present disclosure discloses a computer-implemented method for simplifying analysis of a computer-aided model. The method comprising acts of selecting at least one evaluation point in a standard computer-aided model, analyzing the standard computer-aided model by simplifying each of a plurality of simplification points for the selected at least one evaluation point. Further the computer-implemented method comprises acts of building a response surface using relationship between simplification parameters and evaluation parameter based on analysis of the standard computer-aided model and indicating effect of simplification of at least one simplification point in the computer-aided model by comparing calculated evaluation parameter of the computer-aided model with a threshold evaluation parameter, wherein, the calculated evaluation parameter is derived using the response surface.
