Creating a Detail View
The auxiliary view offers more clarity, but the section view offers an opportunity
to see things otherwise obscured in an orthographic view. To do so, you'll create
a detail view to add clarity:
1. Make certain that the 2013 Essentials project file is active, and then
open c02-04.idw from the Drawings\Chapter​2 folder.
2. Start the Detail tool from the Ribbon or from the context menu.
3. Click the section view as the parent, which will open the Detail View
dialog box.
4. Set Scale to 2 and Fence Shape to Rectangular; then, click near the
O-ring groove, and drag the fence, as shown in Figure 2.10.

5. Drag the new view to any open spot on the page, and click to place it.
Now that you have a collection of views, you should make the drawing look
better as a whole. By moving, rotating, or even changing the appearance of the
views, you can make a big difference.
