3. Select the bottom endpoint of the arc in the same way.
4. Click a point to the left of the arc to place the dimension (bottom of Figure 16.14).
5. At the Dimension text = prompt, press ↵ to accept the current value.

Adding a dimen-

to the arc
Select the arc
at this location
so that the red
circle appears.
Click here to place
the dimension.
Notice that the new dimensional constraint has been given the name d2. Now try changing
the size of the arc using the dimensional constraint:
1. Double-click on the dimension value of the dimensional constraint (Figure 16.15).
2. Enter 2 ↵. The part adjusts to the new dimension.

dimension
As you can see from this example, you can control the dimensions of your drawing by chang-
ing the dimensional constraint's value. This is a much faster way of making accurate changes
to your drawing. Imagine what you would have to do to make these same changes if you didn't
have the geometric and dimensional constraints available.
