Info Tip:
3D modeling employs the concept of applying Boolean operations to open or closed shapes. With surfaces of any curvature, intersections can result in complex curves. Such curves may not be precisely defined. Rather than applying an analytic solution, the program must employ numerical approximation techniques to express these intersections. These approximations occur within the system's user defined tolerance.
