Extend Polygon Sides (Production Mapping)
サマリ
Extends the lengths and widths of polygon features until they meet a specified minimum value.

使用法
A warning is raised if the input features are not in a projected coordinate system. This tool relies on linear distance units, which will create unexpected results in an unprojected coordinate system. It is strongly suggested that you run this tool on data in a projected coordinate system to ensure valid results. An error is raised and the tool will not process if the coordinate system is missing or unknown.
This tool cannot be run on data that is registered as versioned.
-
It is recommended that this tool only be used on regular, rectangular-shaped polygons, such as buildings.
Features with a longer side smaller than the value specified in the Minimum_Length (Minimum Length) parameter will have the longer side extended until it meets the minimum value.
Features with a shorter side smaller than the value specified in the Minimum_Width (Minimum Width) parameter will have the shorter side extended until it meets the minimum value.
This tool cannot be run during an edit session.
