• Through the center of each hole, add a vertical and horizontal line that extends a short distance beyond the circle (like a cross hair). Use manual constraints to force each line to move with the hole and to continue to extend the correct distance beyond the circle when the hole changes size. Hint: Apply Point on and point-to-circle Distance constraints.

• Go back to the original geometry, but first remove the both fillets on the left vertical line of the model. Go through exercise again, including the creation of the equidistant inner contour. This time, Complete will not cause the inner contour to remain equidistant. Why? Can you add manual constraints to fix the problem? Hint: Use Samedist constraints.
