Outline of Final Research Achievements

In this research, the authors attempt representation of traditional wooden building system by programming language. The following results were obtained.
1. Procedures for tsugite-shiguchi can be represented by determining a joint pattern, calculating attitudes of each parts and its joints, and creating shapes that represent subtraction from original lumbers. parametrical Classes for the joints were developed and detailed 3D model of Himeji castle, a conventional house and a traditional wooden temple gate were created with this system. 2. Systematized proportionality relations which are typified as kiwari, part classes including the design method, and the parts structure were studied through the development of a visual programming system. The authors conclude that executable graphical description with visual programming could be used for knowledge representation for building system.
