Build TIN Wizard

Builds a Triangulated Irregular Network from a feature layer

Inputs:

• A  feature layer  (Point, Polyline, Polygon)
• An elevation field - numeric field that will be used

Outputs:

• New polygon Z feature class. All the polygons are triangles that comply with the Delaunay criteria. See TIN notes for more information about Triangulated Irregular Network

Notes :

• The process goes through several steps
  • Collecting the elevation points from the source layer. If the source is a polygon or polyline layer, all the vertices are used.
  • Removing  duplicate points
  • Creating the TIN structure
  • Storing the polygons Z
• To achieve best results when creating TIN from a polyline layer use Generalize Polylines Wizard or Densify Polylines Wizard in order to remove unnecessary points or add points to the long straight segments
• The function should work with no problems on datasets with up to 2 million points.
