Class: DefCurveParam

algeobra~DefCurveParam()

Definition for a parameter of a point on a curve Will calculate the parameter, if the point lies on the curve. In some cases, there might me multiple possible parameters Supported curve objects are: Line, vector (treated as a line from reference to arrow tip), arc, line strip, Bezier, Bezier spline, ellipse
