Abstract
The multiuser type cooperation design work systems configuration by the virtual reality space in a townscape design was examined. Examination about virtual reality space creation was performed, and it experimented about management of a system for the actual design example. The cooperation work in the design through the operator in the cooperation work using the network was considered, and the function was extended. Even if the user was between remote places and the system separated time, it mounted the reference function for the work history so that it could be used in cooperation work.
