Abstract
Mechanical engineers have to consider all product characteristics and properties as well as the deviations from their nominal values. The paper deals with vectorial tolerances. By direct representation of mathematically evaluable tolerances in the CAD-model, the designer can analyse the impact of deviations along the tolerance chain. A focus of the paper is the handling of partially closed tolerance loops. A real product often consists of partially closed tolerance loops. Even if the total tolerance chain can be considered as an open chain, many products have partially closed tolerance loops.
