Delineate TIN Data Area

Redefines the data area, or interpolation zone, of a triangulated irregular network (TIN) based on its triangle edge length.

1. Input TIN

The TIN dataset to process.

2. Maximum Edge Length

The two-dimensional distance that defines the maximum length of a TIN triangle edge in the TIN's data area. Triangles with one or more edges that exceed this value will be considered outside the TIN's interpolation zone and will not be rendered in maps or used in surface analysis.

3. Method (optional)

The TIN edges that will be evaluated when delineating the TIN's data area.

• PERIMETER_ONLY—Iterates through triangles from the TIN's outer extent inward and will stop when the current iteration of boundary triangle edges does not exceed the Maximum Edge Length. This is the default.
• ALL—Classifies the entire collection of TIN triangles by edge length.

Edit TIN 

Edit TIN Tool, TIN Dataset Toolset, Data Management Toolset, 3D Analyst Toolbox:

Edit TIN

Loads data from one or more input features to modify the surface of an existing triangulated irregular network (TIN).

1. Input TIN

The TIN dataset to process.

2. Input Feature Class

The input features and their related properties that will contribute to the definition of the TIN.

• Input Features—The feature whose geometry will be imported to the TIN.
• Height Field— The source of elevation for the input features. Any numeric field from the input feature's attribute table can be used, along with the Z or M values stored in the Shape field. Choosing the <None> keyword will result in the feature's elevation being interpolated from the surrounding surface.
• Tag Field—Assigns a numeric attribute to the TIN's data elements using values obtained from an integer field in the input feature's attribute table.
• Type—Defines the feature's role in shaping the TIN surface. See the tool's usage tips for more information about surface feature types.
• Use Z— Indicates whether Z or M values are used when the SHAPE field is indicated as the height source. Setting this option to True implies Z values will be used, whereas setting it to False results in M values being used.

3. Constrained Delaunay (optional)

Specifies the triangulation technique used along the breaklines of the TIN.

• Unchecked—The TIN will use Delaunay conforming triangulation, which may densify each segment of the breaklines to produce multiple triangle edges. This is the default.
• Checked—The TIN will use constrained Delaunay triangulation, which will add each segment as a single edge. Delaunay triangulation rules are honored everywhere except along breaklines, which will not get densified.
