Tangency Constraints

DimXpert for parts considers the effects tangencies between planes and cylinders have on dimensioning, tolerances, and constraint status. All DimXpert for parts functions support and consider tangency constraints.

Tangency constraints exist where a plane and cylinder are adjacent.
Cylinder type features include boss, cylinder, and simple hole. The angled plane and adjacent tangent cylinders are fully constrained.

The Tangency annotation type appears in the DimXpertManager under the toleranced feature. Tangency annotation types have an origin feature and a tolerance feature.

Tangency constraints are supported for pocket features. They are not created for fillet, notch, or slot features, which have a built-in implied tangency.
