Support for Fully Semantic References for Dimensions in Model-Based Definition
Dimension annotations support semantic geometric references.
User Interface Location: Click Annotate > Dimension.
Release: Creo Parametric 4.0
Benefits and Description
You can watch a video that demonstrates this capability.
Dimension annotations are improved to support semantic references to model geometry. The References dialog box is accessed from the Dimension tab. The dimension attachment references are added automatically, but you can also select additional references to model surfaces. For example, if a dimension is created referencing model edges, you can add the adjacent surfaces as semantic references. The References dialog box is also available for shown (driving) dimensions. You can assign semantic references to shown (driving) dimensions.
