About Creating Datum Axis Referencing Imported Faceted Geometry
You can create datum axis referencing faces, edges, and vertices as follows:
• Through a facet edge.
• Normal to a facet face. The datum axis is created at the point of selection, similar to a field point.
• Through two facet vertices.
• Through two facet faces.
• Through any combination of facet and exact geometric reference for the reference combinations listed above, for instance, through a facet vertex and a native vertex.
Creating Datum Points
You can create standard datum points at any facet vertex. Field datum points can be created on any facet face and are positioned at the pick locations.
