    Abstract: An improved apparatus and method for designing and displaying three dimensional solid representations from a two dimensional drawing. The invention prompts the user to select a two-dimensional view as a profile for extrusion. This is accomplished by selecting all the elements from a geometry to include in the extrusion. Thereafter, the user is prompted to select a front and back cutting face for the extrusion. The system thereafter transforms the selected two dimensional elements into three dimensional geometries.
