ABSTRACT:
A method of drawing a three-dimensional object in a CAD system, which allows the operator to use two-dimensional drawing techniques. The CAD display screen has three view windows for showing a top, front, and side views. The operator draws a figure in one of the view windows and then defines a first geometry point in the next view window by using a cross-hair cursor running across the two adjacent view windows. The use of the cursor gives some constraint to the selection of the first geometry point with respect to the first graphic element. Next, the operator defines a second geometry point also using the cross-hair cursor for constraint, thus creating a second graphic element from the first and second geometry points. Based on the first and second graphic element, a third graphic element is automatically generated and displayed in still another view window.
