<strong>Step 20:</strong> Pick a third hole and perform the same Convert Entities and Cut Extrude steps to set the depth of the next hole. Add an additional 1 1/2 inches (1.5 inches) to the hole depth for a total of 5 15/16 inches. This hole depth will attempt to produce a D5 note (the fifth of the G-major triad). We will leave the fourth hole's depth at its original 4 7/16 inches because this will attempt to produce a G5 note (one octave up from G4). It's difficult to tell if each Cut Extrude produced the intended result, but you can change the view using the Display Style icon shown in the screenshot. By looking at the sideview of our train whistle, we can see that we have four different hole depths. If you would like to check your work, you can select the Evaluate tab and click on the Measure tool. By clicking on the top and the bottom of the drilled holes, SolidWorks will return the length or "minimum distance" between the two points/features.

Now pat yourself on the back; you've completed part 1 of 3. But don't worry, the other two parts will be relatively simple.
