I'm trying to get the Z value and basing it on points.
I've managed to get it working when I have done feature vertices to point and I get a Z value when I select both ends, but can't seem to get a z value if I only select start or end points.
Which version of ArcGIS you are using? What is the service pack? Could you please provide sample data? I cannot reproduce the issue on my machine. I would like to reproduce and see what's going on.
