ArcGIS.Core.Geometry Namespace / MultipatchBuilderEx Class / HasZ Property
Example

In This Topic
    HasZ Property (MultipatchBuilderEx)
    In This Topic
    Gets a value indicating if the MultipatchBuilderEx recognizes Z-values also known as Z-awareness.
    Syntax
    public override bool HasZ {get; set;}
    Public Overrides NotOverridable Property HasZ As Boolean
    Remarks
    A MultipatchBuilderEx always recognizes Z-values, so the getter always returns true. The setter is a non-operation.
    Example
    Construct Multipatch from another Multipatch
    // create the multipatchBuilderEx object
    var builder = new ArcGIS.Core.Geometry.MultipatchBuilderEx(multipatch);
    
    // check some properties
    bool hasM = builder.HasM;
    bool hasZ = builder.HasZ;
    bool hasID = builder.HasID;
    bool isEmpty = builder.IsEmpty;
    bool hasNormals = builder.HasNormals;
    
    var patches = builder.Patches;
    int patchCount = patches.Count;
    
    // if there's some patches
    if (patchCount > 0)
    {
      int pointCount = builder.GetPatchPointCount(0);
    
      // replace the first point in the first patch
      if (pointCount > 0)
      {
        // get the first point
        var pt = builder.GetPoint(0, 0);
        builder.SetPoint(0, 0, newPoint);
      }
    
      // check which patches currently contain the texture
      var texture = builder.QueryPatchIndicesWithTexture(brickTextureResource);
    
      // assign a texture material
      patches[0].Material = brickMaterialTexture;
    }
    
    // update the builder for M awareness
    builder.HasM = true;
    // synchronize the patch attributes to match the builder attributes
    //   in this instance because we just set HasM to true on the builder, each patch will now get a default M value for it's set of coordinates
    builder.SynchronizeAttributeAwareness();
    
    // call ToGeometry to get the multipatch
    multipatch = builder.ToGeometry() as Multipatch;
    
    // multipatch.HasM will be true
