Abstract:
1. A method of manufacturing three-dimensional topographical scale models for the purpose of easy visual measuring and easy understanding of the landform on the model comprising: entering geometry data of terrain into a computer to create a computer-generated three-dimensional contour plan, wherein two dimensional levels are spread vertically, according to an actual measurement, as a high accuracy representation of terrain; based on said computer-generated three-dimensional contour plan, a three-dimensional surface is generated by the computer, as a high accuracy representation of terrain; based on required scale of the model, said computer-generated three-dimensional surface is scaled to the required scale of the three-dimensional topographical scale model; vertical exaggeration is added to said computer-generated three-dimensional surface; based on said computer-generated three-dimensional surface, a program product for a C.N.C. machine is generated by the computer; based on dimensions of said three-dimensional topographical scale model laminating a plurality of selected veneers with machinable dividers there between to make a composition of permanently laminated materials as required for a designated scale model; and based on said computer-generated program product for the C.N.C. machine, the C.N.C. machine cuts and removes all excess material from said composition of permanently laminated materials, creating a smooth-finished surface of landform based on the geometry of the computer-generated three-dimensional surface and exposing permanently laminated levels which are easily visually recognized by kind, for the purpose of easy visual measuring a height on every level on the three-dimensional topographical scale model.
