PROBLEM TO BE SOLVED: To visually check influence of short-circuit, etc., of holes to a layer by reading coordinates of all holes of each layer from a mounted design file, storing the holes in a mesh table when the holes are open and displaying through states of the holes in the Z direction of X, Y coordinates. SOLUTION: This system is constituted of a processor 1 to perform logical calculation, the mounted design file 2 as a magnetic disk device to store hole data, etc., to be required for basic design, a display 3 to display the mounted design file 2 by a three-dimensional image and a keyboard 4 to input a space to be displayed as three-dimensional image in a coordinate. In such structure, X, Y coordinates of the holes are read from mounted design data and the through state of the holes of all layers are held in the mesh table. Next, the shapes of mounted components are read, each coordinate of a line end point is read, the through states of the holes to coincide with the coordinate of the line end point are acquired from the mesh table. And the through states, etc. of the holes are displayed so as to be visualized from the Z direction.
