modifytin

Modify TIN

Modifies a TIN by adding additional data points or breaklines from a feature layer.

a TIN to be modified.
A feature dataset (Point, Polyline, Polygon).
Output TIN name.
An elevation field - numeric field that will be used for elevation values. If the features have Z values, they can be used for elevation. In this case the input string should be "Shape".
Triangulation method to be used - "Points", "Hard breaklines" or "Soft breaklines"

See Surface types for more information about Triangulated Irregular Network.
The modify features can be added as Points, Hard breaklines or Soft breaklines. The elevation values for Hard breaklines are defined by a field or by the Z values of the features. For Soft breaklines the elevation values are calculated from the input TIN.
When Soft breaklines are added to the TIN, the ones outside of the TIN convex hull are ignored.
Features with NULL values in the elevation field are ignored.

Parameters

Expression	Explanation
Function Name	ModifyTin
<input tin>	A String representing the input TIN dataset.
<modify dataset>	A String representing the modify feature dataset.
<output tin>	A String - the full name of the output TIN.
<elevation field>	A String representing the name of the field to be used as a source for the elevations. Use "Shape" to use the feature Z values.
<triangulation type>	A String - possible values are "Points", "Hard breaklines" and "Soft breaklines"

ETSPath used in the table below is the full path to ETSRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETSurface\ETSRun.exe")

Language	Syntax
Python	subprocess.call([ETSPath, "ModifyTin", "input tin", "modify dataset", "output tin", "elevation field", "triangulation type"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "ModifyTin" "input tin" "modify dataset" "output tin" "elevation field" "triangulation type"
.NET using ETSOutX.dll	ModifyTin(input tin, modify dataset, output tin, elevation field, triangulation type)
ArcPy	arcpy.ModifyTin("input tin", "modify dataset", "output tin", "elevation field", "triangulation type")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
