I was working with a line and a point feature class. Those classes are Z enabled. I have created a Geometric Network with those classes with Z enabled also. In the line feature I have a vertical line whose both end points have same x,y but different z values. So in ArcMap this line looks line a point and in ArcScene vertical line show a good length. But the problems are:-
When I click Verify Network Feature Geometry Command then it points to the vertical line and says 1 feature has invalid geometry and When I export DataSet that includes this Network into XML Workspace Document then it can successfully export. But during importing it gives error :-
FDO error: -2147186428 [XML parse error: System error:-2147210927.[Line: 32, column: 167]] zero-length polylines not allowed Field is not editable Can someone help.
As far as I know, the auto-calced Shape_Length field only refers to horizontal length (xy) and doesn't incorporate z values in the calculation. Maybe you could edit this feature so that it has some length > 0? Or maybe delete it if it is not a significant part of the Network Analysis?
Just curious, but what does this vertical feature represent?
This seems like an issue with the tool. Network Analyst and Utility Network Analyst are still very much 2-D tools, or at least the come from that lineage and rely on those associated assumptions.
Two possbible work arounds I can think of: 1. Edit the pipe so it is not "perfectly" vertical, and therefore has a XY length > 0. In reality the pipe is probably not perfectly verticals, right? Maybe it's off by a few millimeters? 2. Edit the pipe so that it is merged with some other feature that has a XY length > 0. The final upside down "L" shaped feature would have x,y,z coordinates of something like (0,0,0), (0,0,10), (1,1,10). thus preserving the vertical infomation and instilling a horizontal length, teh latter seeming to be a be a requirement.
