Combine Polylines

[RusselQuan]

How would you combine a Feature Class of Polylines into a single Single Polyline Objects to reduce the number of Objects from many to one?  The goal is to reduce the number credits for storage, and potentially increase the speed for rendering.

I've tried Dissolve and Merge but the number of Object remains the same as the original.

Thanks.

If you are using ArcMap 10.x and have an Advanced/ArcInfo license, you can try running a multipart to single part tool, then using the unsplit line tool:

http://resources.arcgis.com/en/help/main/10.1/index.html#//001700000040000000

Merges lines that have coincident endpoints and, optionally, common attribute values.

You may need to run a topology check, too, to make sure your polylines are coincident.

Thanks Chris.  It worked!
