We follow the “generate and test” approach to analyse tolerance specifications: Based on toleranced CAD data, non-ideal parts are generated. For these non-ideal parts we propose several visualization methods to reveal the geometric consequences of the defined tolerances on the resulting product. One set of methods is used to reveal the geometric properties of individual assemblies, like surface quality and progress of gaps. The other set is intended for visualizing the spatial relations between multiple assemblies, like collision probabilities, based on a statistical analysis of these assemblies. The intention of these methods is to provide an intuitive view of the complex relations between tolerances and resulting geometry.

Keywords: computer aided tolerancing, visualization, tolerance analysis
