Increase Line Length example

使用

  • 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.

  • The lines are extended from both sides of the center point.

  • If this tool is run in an edit session in ArcMap, you can stop the edit session without saving changes to restore features that have been deleted.
