---

• Extrude Join - Extrude the middle and inner circle out towards the outer edge of the eyelid by 2mm.

Make sure the operation is set to join in the Edit Feature dialog box, then click Ok.

When you Clicked ok in the last operation, Fusion hid the Sketch2 profile that we had created. To make this visible again we need to click the little eye icon next to the sketch.

• Make the Sketch Visible - Click the eye icon next to the sketch named sketch1

---

• Extrude Cut - Select the same profile again, press e to enter Extrude mode and this time type 1mm as the measurement. You will notice that the extrusion of the profile turns red indicating that this is a cut operation.

---

• Extrude Cut - Select the small profile from the sketch, press e to enter Extrude mode, and set the:

  • Direction to Symmetric
  • Extent Type to All
  • Distance to All

• Click Ok - Then click Ok

This will cutout the screw hole in both directions.

To make this next step easier, move the camera so you can see the outside edge of the eyelide. Use the viewcube to move the camera.

• Extrude Cut - Select the square shape along with the rest of the profile from the sketch, press e to enter Extrude mode, and set the:

  • Start to Object and click the flat outside surface of the eyelid
  • Extent Type to All
  • Distance to All
  • Operation to Cut

The finished result:

Mirror function

We can mirror bodies, components, features and faces using the Mirror function. This is a huge timesaver, especially when parts need to be symmertical; we can build one half and mirror the rest.

---

• Mirror - Click the Mirror function from the CREATE toolbar menu.

• Select the Feature - Select the last for features from the Timeline (they are all the Extrude operations we just did)

• Select the Mirror Plane - Click the Mirror Plane option from the Edit Feature Dialog box and then click the YZ Origin plane.

• Click Ok - Click Ok to complete the mirror operaiton.

The Eyelid Model should look like this:
