Toroidil on kaks mõõtmelist elementi, millest üks on mõõde (toroidi väike läbimõõt) ja tema skelettelement on ring, asendielemendid on tasapind (mis sisaldab ringi) ja punkt (ringi keskpunkt).
Hea teada
Nimimudelis on skelettelement tervikliku nimielemendi geomeetriline tunnus. Terviklik nimielement ja selle skelett kuuluvad samasse invariantsusklassi ja neil on sama asendielement. Mittetäiusliku elemendi korral eksisteerib mitu võimalikku skelettelementi samale terviklikule elemendile.
In case of a torus, there are two dimensional parameters, one of which is a size (the small diameter of the torus), and its skeleton feature is a circle. Its situation features are a plane (containing the circle) and a point (centre of the circle).
Hea teada
In the nominal model, the skeleton feature is a geometrical attribute of a nominal integral feature. A nominal integral feature and its skeleton belong to the same invariance class and have the same situation feature. In the non-ideal feature, several possible skeleton features exist for the same integral feature.
