Definition of poly curve (composite curve) Description: An ON_PolyCurve is an ON_Curve represented by a sequence of contiguous ON_Curve segments. A valid polycurve is represented by an array m_segment of Count()>=1 curve objects and a strictly increasing array m_t of Count()+1 parameter values. The i-th curve segment, when considered as part of the polycurve, is affinely reparamaterized from m_t[i] to m_t[i+1], i.e., m_segment[i].Domain()[0] is mapped to m_t[i] and m_segment[i].Domain()[1] is mapped to m_t[i+1].

A value of 1 means the first derivative or unit tangent was discontinuous. A value of 2 means the second derivative or curvature was discontinuous. cos_angle_tolerance - [in] default = cos(1 degree) Used only when c is ON::continuity::G1_continuous or ON::continuity::G2_continuous.
