This work aims to present a proposal for 3D CAD use for production design of partition walls, including the design coordination as an inherent part of the design process. The research was organized adopting three strategies to obtain successive validations regarding the advantages of 3D CAD compared to 2D CAD use. The strategies used were: a pilot case study, data collection and an exploratory experiment. The case study and the exploratory experiment, which were carried out using the proposed method, allowed the conclusion that 3D CAD has advantages over 2D CAD, the former being faster and more effective for spacial interference checking , specially in complex situations. By using a data collection from designs developed with 2D CAD, the research also concluded that the two-dimensional representation has limiting characteristics that may produce analysis errors. It was identified five basic characteristics of the 2D representation that may lead to error: ambiguity, symbolism, simplification, omission and fragmentation. These conclusions have validated the proposal for a method using 3D CAD for production design of partition walls. This proposal presents advantages over the current 2D CAD -based design method. These advantages are related mainly to better visualization and effective use of the automatic tools of CAD packages for interference identification , reducing the representation problems of 2D. Therefore, compatibility analysis becomes more precise and faster. The proposed method is based on modern management models, such as concurrent engineering, decreasing time spent on non-value adding activities, as well as preparing for using of advanced tools like BIM (Building Information Modeling).
