Surface Methods |

The Surface type exposes the following members.

Methods

Name | Description | |
---|---|---|

ClosestPoint |
Input the parameters of the point on the surface that is closest to testPoint.
| |

ClosestSide |
Gets the side that is closest, in terms of 3D-distance, to a U and V parameter.
| |

ComponentIndex |
If this piece of geometry is a component in something larger, like a BrepEdge
in a Brep, then this function returns the component index.
(Inherited from GeometryBase.) | |

ConstructConstObject |
Assigns a parent object and a subobject index to this.
(Inherited from CommonObject.) | |

CreateExtrusion |
Constructs a surface by extruding a curve along a vector.
| |

CreateExtrusionToPoint |
Constructs a surface by extruding a curve to a point.
| |

CreatePeriodicSurface |
Constructs a periodic surface from a base surface and a direction.
| |

CreateRollingBallFillet(Surface, Surface, Double, Double) |
Constructs a rolling ball fillet between two surfaces.
| |

CreateRollingBallFillet(Surface, Point2d, Surface, Point2d, Double, Double) |
Constructs a rolling ball fillet between two surfaces.
| |

CreateRollingBallFillet(Surface, Boolean, Surface, Boolean, Double, Double) |
Constructs a rolling ball fillet between two surfaces.
| |

CurvatureAt |
Computes the curvature at the given UV coordinate.
| |

Degree |
Returns the maximum algebraic degree of any span
(or a good estimate if curve spans are not algebraic).
| |

Dispose |
Actively reclaims unmanaged resources that this instance uses.
(Inherited from CommonObject.) | |

Dispose(Boolean) |
For derived class implementers.
(Inherited from CommonObject.)This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method. You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true. Also, you must call the base virtual method within your overriding method. | |

Domain | Gets the domain in a direction. | |

Duplicate |
Constructs a deep (full) copy of this object.
(Inherited from GeometryBase.) | |

DuplicateShallow |
Constructs a light copy of this object. By "light", it is meant that the same
underlying data is used until something is done to attempt to change it. For example,
you could have a shallow copy of a very heavy mesh object and the same underlying
data will be used when doing things like inspecting the number of faces on the mesh.
If you modify the location of one of the mesh vertices, the shallow copy will create
a full duplicate of the underlying mesh data and the shallow copy will become a
deep copy.
(Inherited from GeometryBase.) | |

EnsurePrivateCopy |
If you want to keep a copy of this class around by holding onto it in a variable after a command
completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can
call this function as many times as you want.
(Inherited from CommonObject.) | |

| |

Extend |
