zin_ina@mail.ruPresent CAD systems offer insufficient support of a mixed top-down and bottom-up design mode and hardly offer any suitable functionality for 3D tolerancing. In addition, the state-of-the-art 3D CAD systems engineering fail to deal with uncertainties since only fixed parameter values are allowed for their modeling operations. So support on conceptual design phase is not provided. Based on considerations discussed in the preceding we present a CAD system architecture intended to show how the process of computer-aided design can be improved in the sense of providing 3D assembly tolerancing based on interval analysis.
