IReverseEvaluate Method (IFace2)

Gets the UV parameters for the given XYZ location on this face.

.NET Syntax

Visual Basic (Declaration) 
Function IReverseEvaluate( _
   ByVal PositionX As System.Double, _
   ByVal PositionY As System.Double, _
   ByVal PositionZ As System.Double _
) As System.Double
Visual Basic (Usage) 
Dim instance As IFace2
Dim PositionX As System.Double
Dim PositionY As System.Double
Dim PositionZ As System.Double
Dim value As System.Double
 
value = instance.IReverseEvaluate(PositionX, PositionY, PositionZ)
C# 
System.double IReverseEvaluate( 
   System.double PositionX,
   System.double PositionY,
   System.double PositionZ
)
C++/CLI 
System.double IReverseEvaluate( 
&   System.double PositionX,
&   System.double PositionY,
&   System.double PositionZ
) 

Parameters

PositionX
X coordinate of this location on the face
PositionY
Y coordinate of this location on the face
PositionZ
Z coordinate of this location on the face

Return Value

  • in-process, unmanaged C++: Pointer to an array of doubles for the U and V parameters
  • VBA, VB.NET, C#, and C++/CLI: Not supported

 

See In-process Methods for details about this type of method.

Remarks

This method returns corrected UV parameters for periodic surfaces; thus, you should use this method when dealing with periodic surfaces.

For example, you can have a cylindrical surface that extends from 0 to 2pi in the Udir. The face related to this surface in some cases extends from 0 to pi, then from 0 to pi again. In this case, neither ISurface::IReverseEvaluate nor ISurface::ReverseEvaluate will work for values greater than pi (the returned U value will be greater than Maximum U for the face). However, IFace2::IReverseEvaluate, and IFace2::ReverseEvaluate, will return the correct values.
