ETG_EraseTinWithPolygons

Erase TIN with Polygons

Erases a TIN dataset with the polygons of the input polygon feature class.

A new TIN.
The boundaries of the erasing polygons are traced as soft breaklines within the TIN.
All triangles inside of the erasing polygons are marked outside of the data area and will not be visible.

Result TIN

The output TIN will have all triangles within the boundaries of the erase polygons marked outside of the data area.
If the erase dataset is not with the same spatial reference as the input TIN, it will be projected to the spatial referense of the TIN and the erasing will be done with the projected features. If projection parameters can not be established, no output will be created and an error will be recorded in the Log file.

Parameters

Expression	Explanation
Function Name	EraseTinWithPolygons
<input TIN>	A String representing the input TIN dataset.
<output TIN>	A String - the full name of the output TIN.
<erase dataset>	Erase Polygon dataset

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, "EraseTinWithPolygons", "input tin", "output tin", "erase dataset"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "EraseTinWithPolygons" "input tin" "output tin" "erase dataset"
.NET using ETSOutX.dll	EraseTinWithPolygons(input tin, output tin, erase dataset)
ArcPy	arcpy.EraseTinWithPolygons("input tin", "output tin", "erase dataset")

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.
