The purpose of this study is building the part of hipped roof angle rafter generation of the frame element generation system by cooperation of constituents in timber framework construction house. The part of hipped roof angle rafter generation is built as a multi agent system that the angle rafter modeled in the straight line cooperates with close angle rafters, repeats correction and decide the right position based on positioning rules by analyzing the positioning situation of angle rafter in hipped roofs and the information of the circumstances. In this study, the knowledge that is obtained on the building this part is reported.
