Abstract
An 3D solid modeling software has been developed for the education of the descriptive geometry, mathematics and computer graphics. The boundary representation and the winged-edges method have been adopted as a description method of solid model. The developed solid modeler can create a 3D solid model by executing the command lines of text format. The solid modeling method with mathematical functions was developed. This function is useful for the education of the mathematics because of the 3D display of the mathematical functions. The developed software has several kinds of display modes such as the edge-type and the surface-type display modes.
