4.10.2.1.1 PolyCurve Profile Definition

Poly curve profile definitons define the closed two-dimensional curve used for the cross-section by a indexed poly curve having straight and circular arc segments.

NOTE  The indexed poly curve has been introduced to provide a less complex and less data set size consuming definition compared to the composite curve.

Figure 101 illustrates an instance diagram.
