MakePatch Method—ArcGIS Pro

Creates an empty Patch that inherits attribute awareness from this builder.

Syntax

C#
Visual Basic (Declaration)

public Patch MakePatch( 
   esriPatchType patchType
)

Public Function MakePatch( _
   ByVal patchType As esriPatchType _
) As Patch

Parameters

patchType

Remarks

The Patch will inherit the attributes of this MultipatchBuilderEx such as HasM, HasID, and HasNormals. The new patch will have no texture coordinates.
