Joining lines

Question

Hello guys,

I have a polyline shapefile with hundreds of line segments. It�??s actually a city street network. But as the shape file was created from CAD file, not all the lines are continues where they should be. For example, if you look at the attached Exhibit-1, between node 1 and node 2, there are 4 different line segments (I colored the lines so that it�??s easy to understand). But I want to make those lines a single continuous line. That is, there should be only one connecting line segment between any two nodes/ intersections. Is there any way to do that? Your help would be highly appreciated.

Thanks
Shafayat

If all lines already end where they intersect, as your image shows, you can unsplit lines between intersections/node in one process, either using Dissolve with the Unsplit Line option and uncheck "create multipart" or better using Unsplit Line tool (new in arcGIS 10).

Thank you very much Juan and Thales...I was able to do what I wanted to do...

First I dissolve the entire shapefile, it combined all the lines and returned one polyline.

Then I used Feature to Line tool, it splited lines at points where two or more lines intersect 🙂
