OdDgBSplineCurve2d::getChordLenTangentsFlag Method
Syntax
C++
bool getChordLenTangentsFlag() const;

Control scale of start and end tangents. If true than tangent scaled by 1/3 of the chord length, defined by first two points or last two points. Otherwise tangents are scaled by Bessel length tangent formula.
