For ArcGIS 10.1, is there a python script or tool that will add only one vertex (node) a set distance from the first vertex, or alternatively, a set distance from the last vertex for multiple polylines? The original vertices need to be retained for each polyline.
I have over 500 polylines and creating vertices individually in an edit session is taking forever!
x
units, but I don't think it'll stop at just one so may not entirely suit your needs. Note this modifies your data, it doesn't create a separate output
