You can display or hide all the dimensions for all the features of the part. Then you can turn the display of dimensions on and off, either individually, or on a feature-by-feature basis.
Right-click the Annotations fm_annotations.png folder in the FeatureManager design tree, and select Show Feature Dimensions.
All the dimensions for the part appear. Notice that the dimensions that are part of a feature’s definition (such as the depth of an extruded feature) are blue.
