DimXpert Show Tolerance Status

The DimXpert Show Tolerance Status tool identifies the manufacturing features that are fully constrained, under constrained, and over constrained from, primarily, a dimensioning and tolerancing perspective. However, certain geometric relationships between features and the orientation of each feature relative to the annotation views are also considered.

Examples

These examples illustrate the effect that dimensions and tolerances have on tolerance status.

Fully Constrained
Plus and minus dimensions
Geometric tolerances

Under Constrained
In this example, a size tolerance is missing from the two-hole pattern and the right hand plane is not dimensioned or toleranced.
In this example, the holes are not located along the horizontal direction, and a size tolerance is missing from the corner fillets.

Over Constrained
The hole pattern is located from the left and right hand planes and there is a dimension applied between the left and right hand planes. Removing any of the four dimensions applied to the four features would resolve the over constrained condition.
