SurfaceEvaluator.getIsoCurve Method
Parent Object:
SurfaceEvaluatorDefined in namespace "adsk::core" and the header file is <Core/Geometry/SurfaceEvaluator.h>
Description
Gets (by extraction) a curve that follows a constant u or v parameter along the surface. The curve will have the same properties as the surface in the direction of the extraction. For example, when a curve is extracted from the periodic direction of a surface, the extracted curve will also be periodic. The type of curve returned is dependent on the shape the surface.
Getting an iso curve is limited to a SurfaceEvaluator that is obtained from a BRepFace. It will fail when the SurfaceEvaluator is obtained from a geometry object (Plane, Sphere, Torus, Cylinder, Cone, EllipticalCone, EllipticalCylinder, or NurbsSurface).
Syntax
"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object.returnValue = surfaceEvaluator_var.getIsoCurve(parameter, isUDirection) |
"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object.
#include <Core/Geometry/SurfaceEvaluator.h>
returnValue = surfaceEvaluator_var->getIsoCurve(parameter, isUDirection);
|
Return Value
| ObjectCollection |
Returns an ObjectCollection that contains one or more curves. Multiple curves are returned when the SurfaceEvaluator is obtained from a Face and the curve cuts across internal boundaries. The resulting curves are trimmed to the boundaries of the Face. When the SurfaceEvaluator is obtained from a geometry object, a single curve is returned because there are no boundaries to trim the curve. The type of curve(s) returned is dependent on the shape of the surface. |
Parameters
| parameter |
double |
The parameter at which to extract the curve |
| isUDirection |
boolean |
A bool that indicates whether to extract the curve from the U or V direction |
