SurfaceProxy Methods

The SurfaceProxy type exposes the following members.

Methods
  NameDescription
Public methodCode exampleClosestPoint
Input the parameters of the point on the surface that is closest to testPoint.
(Inherited from Surface.)
Public methodClosestSide
Gets the side that is closest, in terms of 3D-distance, to a U and V parameter.
(Inherited from Surface.)
Public methodComponentIndex
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.)
Protected methodConstructConstObject
Assigns a parent object and a sub-object index to this.
(Inherited from CommonObject.)
Public methodCode exampleCurvatureAt
Computes the curvature at the given UV coordinate.
(Inherited from Surface.)
Public methodDataCRC
Returns a CRC calculated from the information that defines the object. This CRC can be used as a quick way to see if two objects are not identical.
(Inherited from GeometryBase.)
Public methodDegree
Returns the maximum algebraic degree of any span (or a good estimate if curve spans are not algebraic).
(Inherited from Surface.)
Public methodDeleteAllUserStrings (Inherited from GeometryBase.)
Public methodDeleteUserString (Inherited from GeometryBase.)
Public methodDispose
Actively reclaims unmanaged resources that this instance uses.

Public methodDomain

Public methodDuplicate
Constructs a deep (full) copy of this object.
(Inherited from GeometryBase.)
Public methodDuplicateShallow
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.

This routine accepts a 3-d trim curve (trimCrv3d).

We refer to that parameter as the "trim parameter". The routine splits the surface via the trim curve, and then refits either side ("upper" = "above the trim", and "lower" = "below the trim") as a set of untrimmed Nurbs surfaces. The idea is to retain, as much as possible, the Nurbs structure of srf, especially in the trim parameter.
