Example

Create TinEditor from TinDataset

tinEditor = new TinEditor(tinDataset);
isInEditMode = tinEditor.IsInEditMode;  // isInEditMode = true

Edit an existing TIN

// Create an instance of TinEditor from an existing TinDataset
tinEditor = new TinEditor(tinDataset);
int numNodes = tinDataset.GetNodeCount();  // numNodes = 10
tinEditor.AddPointZ(pointZ, 7);

// Calling SaveEdits modifies the existing TIN
tinEditor.SaveEdits();
numNodes = tinDataset.GetNodeCount();  // numNodes = 11

// Adding twenty points
tinEditor.AddMassPoints(points, 10, 112.5);

// Calling SaveAs creates a new TIN on disk, and 
// the tin editor points to the new TIN.
string tinPath2 = "C:\\Tin2";
tinEditor.SaveAs(tinPath2, true);

tinEditor.StopEditing(true);
TinDataset tinDataset2 = OpenTin(tinPath2); // See https://github.com/esri/arcgis-pro-sdk/wiki/ProConcepts-3D-Analyst-Data#working-with-tin-data
numNodes = tinDataset2.GetNodeCount(); // numNodes = 31

// The edits still show up in the original TIN while it is in memory, but if you open it
// again you will see that it only has the edits that were saved before SaveAs was called.
numNodes = tinDataset.GetNodeCount(); // numNodes = 31

tinDataset = OpenTin(tinPath);
numNodes = tinDataset.GetNodeCount(); // numNodes = 11
