Create a line that is parallel to an existing line.
Parallel lines can be created at an approximate distance or an exact distance from the original line.
It is possible to create self-crossing lines using this command. Check for these using validation commands. See “Validation” on page 1149. |
This command uses the following Display Units options:
• Coordinate Measurements Reference
• Distance Units and Precision
See Options for details.
Results will generally be better using a projected coordinate reference system than with the Geographic (Lat/Lon) coordinate reference system which is not projected by definition. See Select Coordinate Reference System for information on selecting a coordinate system.
