Abstract
In a design, when defining parameters, generally the value that a designer can satisfy is found out using the calculating methods, such as the optimum designing method and the satisfactory designing method. However, since the influence to the performance and conditions which each parameter does etc. is grasped, the value of a variable is changed and work of repeating inquiring and performing it may be performed. This is called “Parameter Study”. In this paper, in order to enable it to perform a Parameter Study Tool visually, I made the parameter study tool using 3D-Graphics build, and decided that it applies to some exercises and inquires.
