Extruding a Thin Feature

  1. Select the top face of the model in the graphics area.
  2. Click Extruded Boss/Base on the Features tab.
  3. Click Offset Entities on the Sketch tab.
  4. In the PropertyManager:
    1. Set Offset Distance to 2.
    2. Select Reverse to offset the edge to the inside.
  5. Click OK to create the sketch.
    You used the Offset Entities tool to create the sketch so you could efficiently and easily control the offset distance from the model's outer edge to the inner edge of the extrude feature you are creating. You could have created the sketch using the Circle tool, but this would have required more steps.
