The bezier line option will produce an arch with a height
given by the dimension (A h ) while the rounded shoulder
option uses the dimension as a radius and tries to fit a
quarter circle section of the given radius (A r ) at the
shoulders. If the radius for the shoulder circles is greater
than half the Drive width then one circle of the given radius
will be fitted at the top.
Figures 2.6 shows examples of the various arch types
possible. In all these figures the Height(H) is 4m and the
Width(W) is 4 metres. Figure 2.6a, A h = 1m, Figure 2.6b:
A r = W/2 = 2m, Figure 2.6c: A r = 1m and Figure 2.6d: A r =
3m.
