Parent Object: CurveEvaluator3D
Defined in namespace "adsk::core" and the header file is <Core/Geometry/CurveEvaluator3D.h>

Description

Get the parameter position that correspond to a point on the curve. For reliable results, the point should lie on the curve within model tolerance. If the point does not lie on the curve, the parameter of the nearest point on the curve will generally be returned.

Syntax

"curveEvaluator3D_var" is a variable referencing a CurveEvaluator3D object.

(returnValue, parameter) = curveEvaluator3D_var.getParameterAtPoint(point)
 

#include <Core/Geometry/CurveEvaluator3D.h

// Declare the output arguments.
Ptr<Point3D> point;
double parameter;
boolean returnValue = curveEvaluator3D_var->getParameterAtPoint(point, parameter);

Return Value

Type Description
boolean Returns true of the parameter was successfully returned.
