Set Representation Control Point By Angle (Cartography)
Summary
Places a representation control point at vertices along a line or polygon outline where the angle created by a change in line direction is less than or equal to a specified maximum angle.
Illustration
 |
Dash placement can be improved along a line or polygon outline when representation control points are placed at prominent angles |
Usage
-
Input features must be a line or polygon layer symbolized with a representation.
-
The modification to vertices is stored as a geometry override on the feature representation.
Syntax
| Parameter | Explanation | Data Type |
in_features |
The input feature layer containing line or polygon representations. | Layer |
maximum_angle |
The angle used to determine whether or not a vertex along a line or polygon outline will be set as a representation control point. The angle value must be greater than zero and less than 180 decimal degrees. | Double |
Code Sample
The following Python window script demonstrates how to use the SetRepresentationControlPointByAngle tool in immediate mode.
import arcpy
from arcpy import env
env.workspace = "C:\data"
arcpy.SetRepresentationControlPointByAngle_cartography("trails.lyr", "135")
This stand-alone script shows an example of using the SetRepresentationControlPointByAngle tool.
