Abstract: The simulation modeling is the unique way to perform the inevitable
3D tolerance calculation in CAD supported design. A known functional model of a mechanical
unit is used as platform for the proposed solution of dimensional problems. The emerging
data organization and procedural components are analyzed. Some arising processing
particularities of the incorporated formal approach of matrix operators are discussed.
A set of related object classes for implementation of dimensional calculations in the
context of used model and approach is proposed. Particular properties of the application
are clarified.
Keywords: CAD, functional model, machine design, tolerance, object modeling.
