If I can rotate this object properly, I should be able to add it to the left edge of the
rectangle. But, before I start rotating, it will be useful to resize the object so its
diameter matches the width of the rectangle where it will be added. While I'm at
it, I'll go ahead and reduce its thickness (height) to 3mm to match the rectangle.
Figure 7.5 shows that I've resized the Round Roof object.
Figure 7.5 Resize object to match medallion's thickness and diameter.
Next, I need to rotate the flattened Round Roof object along the X axis. To do this,
I move my mouse over the X-axis rotation arrow icon and click and hold as I drag.
