I have a feature with hundreds of lines and I need to extend all the lines of a given distance (for example all of 100 meter).

Is there a function in ArcGIS to do it automatically?

  • Extend in what direction? Could you add a screenshot? – BERA Mar 15 '19 at 16:12
  • In the same direction aof the original line. In now they are straight line and i at the and i still want straight lines with the same direction but longer as in original. I need it to make profile of a river, but now the lines dont cover the whole river – tera santa Mar 15 '19 at 16:29

    Try Extend Line. I have not tried it but it seems you need to have a "stop" feature in the same feature class as the input. For example try buffering the river, convert to polyline and append this to the input. Then run the tool – BERA Mar 15 '19 at 18:11
  • That could work for most cases but I will have problems where the lines will intersecate itself before reaching the stop feature – tera santa Mar 17 '19 at 19:19

I am assuming that you are using the ArcMap application of the ArcGIS Desktop product. You have tagged the latter, but then you have supplied a link to ArcGIS Online within your question body.

To do this I think you should test the Extend Line tool which:

extends line segments to the first intersecting feature within a specified distance. If no intersecting feature is within the specified distance, the line segment will not be extended.

If this does not meet all of your line extending requirements then you may want to include a picture and description of one requirement that it does not meet within your question.
