1. A computer aided design station for designing and tolerancing a modeled object, comprising: a display to display the modeled object; an interface to receive a user input relating to the modeled object; and a processor configured to select a geometrical feature of the modeled object based on the user input, search in a catalog for tolerance scheme templates corresponding to the geometrical feature, the tolerance scheme templates specifying a geometric tolerance for the geometrical feature, display, on the display, tolerance scheme templates corresponding to the geometrical feature, select a tolerance scheme template from the displayed tolerance scheme templates based on the user input, and apply the selected tolerance scheme template to the geometrical feature of the modeled object, wherein the processor searches the catalog for the tolerance scheme templates corresponding to the geometrical feature using randomly generated universal unique identifiers that uniquely identify a geometrical template corresponding to the selected geometrical feature.
