About the Datum Point Feature
You can use datum points as a construction element when modeling geometry or as a known point for conducting computations and model analyses. You can add points to your model at any time, even while in the process of creating another feature.
To add datum points to your model, use the Datum Point feature. A Datum Point feature can contain multiple datum points that are created during the same operation. Datum points that belong to the same feature behave as follows:
• In the Model Tree, all datum points appear under one feature node.
• All points in the Datum Point feature act as a group. Deleting a feature deletes all points in that feature.
• To delete an individual point in the Datum Point feature, you must edit its definition.
Different Types of Datum Points
Creo supports three types of datum point that vary depending on their method of creation and use. Note that the first two types are used in regular modeling. You can select from the following types of datum points:
• General point—A datum point created on an entity or at the intersection of entities, or offset from an entity.
• Offset from a coordinate system—A datum point created by offsetting from a selected coordinate system.
• Field point—A point used in Behavioral Modeling for analysis purposes. A field point identifies a geometric domain.

 Models created in versions of Pro/ENGINEER earlier than Wildfire 3 might contain legacy sketched datum point features. When you work with these features, you will receive a warning message. Click  Edit Definition to redefine sketched datum points, and they will be converted to regular Sketch features. |
