Selecting Valid Edges and Surfaces for Referencing
When you create an intent surface or an intent chain, a valid selection can consist of one or more surface sets or one or more edge chains. Valid surface types are quilts, surfaces of quilts, and solid surfaces. Valid edge types are quilt and solid edges.
You also can define an intent surface with one or more edge chains that reside on the same surface or quilt. The edge or edges you select must divide the surface into at least two regions and may not intersect.
Model > Datum > Reference is not available if you select invalid objects or a combination of valid and invalid objects.
You can set up the selection filter to exclusively select objects. The selected datum references are highlighted and can be previewed. The selected edges are highlighted in red, and the selected surfaces appear with a red mesh or red shading depending on the selected display style.
