In this study, we consider a parallel relation of architectural plane description by Sight-Depth which was proposed by front manuscript and psychological quantity. Simulator was used with point which calibration Sight-Depth and they went along psychological experiment according to SD method. A factor analysis was performed and the description by 3 factor pieces. As the result the description by Sight-Depth and psychological quantity was parallelism, it understood comfort, the discontinuous length largest value simplicity of a surface as for Sight-Depth-Area. The mental implications which Sight-Depth has conformed and a computation of clearness and a precise architectural plane became possible.
