ABSTRACT:
A design system for designing, dynamically changing and displaying design drawings. The invention allows a user to select a solid object from a display as the current, active object. The user then selects a first, parent face by selecting any point on a face of the solid object. Next, the user is prompted to select another point on a line of another face parallel to the first face. This operation defines the first offset face which is a variable distance from the first parent face. Subsequently, the user selects a point on a line to define a second parent face of the solid object. Then, the user selects a point on a line parallel to the second parent face. This defines the offset face and a corresponding distance between the two faces which is a fixed value. Finally, the user is prompted to enter a new distance between the first parent face and the first offset face. This new value is used to generate a new solid based on a change to the variable distance between the first two faces and a corresponding shift in the location of the fixed distance between the second pair of faces and a resulting modification of the surface.
