Abstract
The invention provides a method for creating a three-dimensional solid model from a two-dimensional projection drawing created on a CAD screen via a simple operation. Reference points P1, P100 and P200 are respectively selected on a front view, a plan view and a right side view of a CAD screen. Line L1 is selected in step (1), and points P100 and P101 are selected in steps (2) and (3). By selecting lines L200 and L201 in steps (4) and (5), the coordinates of three-dimensional elements L300 and L301 are recognized. Thereafter, the procedure is repeated sequentially to recognize the whole shape of the product via points and lines. By recognizing closed shapes surrounded by lines as surfaces, it becomes possible to create a three-dimensional solid model via a simple method.
