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
