For the architecture and construction industries, using computer-aided design (CAD) software as an aiding tool to its drafting tasks is very common, however, drafting operates mainly in 2D. Not only it takes a long working time, but is also hard for operators to detect human errors. Using the 3D parametric drafting can reduce the design conflicts through simulations and prevent conflicting problems during construction. Meanwhile, the 3D modeling resolves data scattering problem, thus saves the time on repeated design modifications. The drafting data generating from the 3D model are in consistency and the occurrence of errors is diminished. This research uses IDEF0 methodology to reengineer the design processes in the precasting construction and establishes the modules that enable the parametric drafting automation system for precasting structures. In addition, several functional modules are also created for the key steps in the current work preoces. The automatic processing not only improves the efficiency of drafting, reduces human errors and lowers the cost on making-up the errors, but also achieves the goal of data integration using database.
