Trying to figure out how to edit a self intersecting polyline (Interstate Ramp) such that I end up with a from node, self intersection loop, then end node.
I'm using ArcGIS Version 10.3 and the data is stored in a Feature Class of a File Geodatabase
Richard. Great and insightful comments, but I think I found a solution from which we both might find useful. I found that if, as you stated, I create two features, then retrace the features (ramp), then delete the underlying features I was left with one self-intersecting line that appears to work fine in network analyst (See Figure). The only issue I have now is when I trace the new feature I lose all attribution so I suspect some sort of join to repopulate the attributes.
To copy attributes from one feature to another feather I used the following procedure ....
1.Click the Editor menu and click Start Editing.
2.Click the Edit tool Edit tool on the Editor toolbar.
3.Select the features whose attributes you want to edit.
4.Click the Attributes button Attributes button on the Editor toolbar.
5.In the Attributes dialog box, right-click the feature you want to copy from and click Copy.
6.Right-click the feature you want to paste into and click Paste.
