Press Esc, and click the triangular grip located near the midpoint of
the curve. Move your cursor to a different location without clicking.
This grip controls the radius of the curve while maintaining tan-
gency at both ends of the curve (see Figure 5.7).

Press Esc, and click the square grip at the end of the Jordan Court
alignment. Move your cursor to a different location without clicking.
This type of grip is located at either the beginning or the end of
the alignment. As it's moved, the geometry adjacent to it responds.
In the case of this alignment, the curve just before the endpoint
changes the locations of its beginning and ending points to remain
tangent at both ends (see Figure 5.8).

7.
Press Esc, and click the square grip located at the midpoint of the
last tangent in the alignment. Move your cursor to a new location
without clicking.
This grip moves the tangent while maintaining its orientation
in the drawing. Adjacent geometry responds as needed to meet its
geometric rules. In the case of this alignment, the PI to the left of
