||The principal theme of this research is to provide information regarding the implementation of 3D Model CAAD, CAAD system which uses 3D Drawing Production Method (DPM) instead of 2D DPM This research is focused on its implementation in architecture firms and on justifies its performance and investment value. Principally there are two evaluations conducted in this research. First evaluation aimed to justify 3D-Model CAAD influence on design process and the second is investment evaluation which aimed to provide information for current and prospective user regarding their current and future investment on 3D-Model CAAD.
The results of the evaluations are: 3D Model CAAD has improved performance through efficiency on time and cost of design process also improvement on design quality. However correlation between the use of 3D-Model C.4AD and better performance, while tested using Chi-Square Test, is not significantly. This fact indicates that there are some other strong factors to influence design performance. Second, 3D-Model CAAD, according the Importance-Performance Map is positioned at top right quadrant which categorised as 'keep the good work' which means it has good investment value.
