FIGURE 1.31
Creating a midpoint relation between a centerline and a line
FIGURE 1.32
Making the rectangle symmetric about the centerline
13. Drag one of the corners of the rectangle from inside the circle and drop it on the cir-
cumference of the circle itself. The point here is that you want the corner of the circle to
be right on the circle always. A coincident relation is created by the drag-and-drop action.
Now when you move either the circle or the rectangle, the other may change in size. Try
dragging the circle itself, a corner point of the rectangle, or a line of the rectangle. Try drag-
ging the centerline and the free endpoint of the centerline. Notice that the result of moving
each different sketch entity is different from any of the others.
14. Click the Smart Dimension tool in the Sketch toolbar or choose Tools ➪ Dimensions ➪

You can align the dimension one of three ways: measuring the horizontal dimension of the
