I have a 2D polyline feature class representing underground utilities of various types. Lets say for sewers I have a simple line but no elevation values were included in the attribute from the CAD files. I can look at the CAD drawing PDF's that were provided and ascertain the start and end elevations of each pipe. I see there is a tool "Feature to 3D by Attribute" where I can put these start and end elevations in the attribute table and convert the 2D line to 3D.
My question is, how do I know which field applies to one end of the line vs the other? Does the tool attribute one field to one end and the other field to another end based on direction or something like that? For instance, field 1 is the northern/eastern most end of the line and field 2 is the southern/western most end of the line?
Have you had any luck with figuring this out? I'm working with a similar situation where I need to assign upstream and downstream elevations to a 3D pipe.
At the moment am trying to figure the same thing. May I ask you if you managed to find the ideal tool/s?
We've modified our workflow to populate upstream and downstream elevations as attributes, then export Feature to 3D, then add our attachment to the pipe segments.
