Creating a Feature with an Internal Sketch and Embedded Datum Plane

The next solid feature to be created is an Extruded Cut to hollow out the PISTON.   In order to capture the desired dimensioning scheme for the cut, its sketch will be placed on a datum plane offset from the top surface of the model. 

We will start the Extrude tool and create an internal sketch and a datum plane with the Extrude dashboard open.  When the Extrude tool is completed, the system automatically places the sketch and datum plane in a branch within the extrude feature in the model tree.  This technique allows us to edit and manipulate several features as one.

 

Task 2-6. Start the Extrude tool and then create an embedded datum plane.

  1. Start the Extrude Tool from the feature toolbar (right of the screen).
  2. Click the Placement Tab in the dashboard. (bottom of the screen) 
    • Click Define to define an Internal Sketch.
  3. Drag the Sketch dialog box to expose the feature toolbar on the right of the screen
    • Start the Datum Plane Tool .
  4. Select datum plane TOP from the model, and drag the white offset handle downward to 2.
  5. Click OK from the Datum Plane dialog box.
