    • PROBLEM TO BE SOLVED: To provide a method and a device for conducting gap stack-up analysis on interacting machine parts in order to generally calculate the tolerances of the machine parts, or more specifically, the nominal size and the tolerance of a gap.
      SOLUTION: A method and a device for conducting gap stack-up analysis on a machine gap are provided. The gap is defined by the opposing surfaces of two machine parts. A vector loop starts on one of the opposing surfaces, traverses the machine parts affecting the gap size, and ends on the other of the opposing surfaces. The size and tolerance related to each of the parts within the vector loop are coupled to provide the gap size and gap tolerance. In one embodiment, gap stack-up is determined by a computer program product executed by a computer processor.

    • PROBLEM TO BE SOLVED: To provide a CAD system and an implementing method for a computer, which automatically generates a tolerance scheme. SOLUTION: The method for the computer that automatically generates the tolerance scheme, has the steps comprising: accessing a data for defining a 3D model for specifying a part to be manufactured; identifying a form with tolerances in the 3D model; determining at least one of a degree of controls without any constraint for the form with tolerance; automatically generating the tolerance scheme for the form having the tolerances; rendering the tolerance scheme and the 3D model into a window in a manner that the tolerance scheme adds a note to the form having the tolerances; and constraining the degree of the controls without any constraint by using the tolerance scheme based on the industrial standard for communicating the tolerances.
