ArcGIS.Core.Geometry Namespace / MultipatchBuilderEx Class / MakePatch Method
The patch type to make
Example

In This Topic
    MakePatch Method
    In This Topic
    Creates an empty Patch that inherits attribute awareness from this builder.
    Syntax
    public Patch MakePatch( 
       PatchType patchType
    )
    Public Function MakePatch( _
       ByVal patchType As PatchType _
    ) As Patch

    Parameters

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