The Create Curve From End Of Object command enables you to draw a curve tangent to the end
of your chosen line or arc.
The command prompts you to choose an object to serve as the beginning of your curve. You
can then specify a radius and an additional parameter (such as Delta or Length) for the curve or
the endpoint of the resulting curve chord (see Figure 1.35).

The Create Reverse Or Compound Curves command allows you to add additional curves to
the end of an existing curve. Reverse curves are drawn in the opposite direction (i.e., a curve to
the right tangent to a curve to the left) from the original curve to form an S shape. In contrast,
compound curves are drawn in the same direction as the original curve (see Figure 1.36). This
tool can be useful when you are re-creating a legal description of a road alignment that contains
reverse and/or compound curves.
