Rotational Dimension Patterns (continued) When creating a rotational dimension pattern of a sketch-based feature, it is recommended that the angular dimension belong to a datum plane in the same group.  The datum plane can be used for either the sketching plane or the reference plane for the sketch.

Task 2-32. Examine and modify the group of features comprising the tab on the ENGINE_COVER_2.PRT.

1. Click Open from the main toolbar, select ENGINE_COVER_2.PRT, and click Open.
2. Expand the EXTRUDE_3 group in the model tree and examine the existing features.
   1. The datum plane (DTM2) and Sketch 3 were created with the Extrude dashboard paused, allowing the features be auto-grouped with Extrude 3.
   2. DTM2 was utilized as the reference plane for the sketch at a 45� angle.
