Abstract
For the cooperative design activities by a design team, a designer needs design object information not only about geometrical data and these attributes but also the design rationale such as the reason of decision making to understand ideas of the design proposes by other designers. To cope with such situation, we focused on influential relations between parts of design object, and previously proposed description supporting method for influential relations between parts. In this report, description method for the measures to influential relation is proposed. Typical measures to influential relation is classified into five types. Then by adding description of measures to influential relation as a case data, our proposed sytem can indicate not only influential relations candidate but also measures which had be done to them.
