Adding z-coordinates for underground infrastructure

[ErinKennedy]

Hello all,

I am trying to model underground pipes in 3D. I have polyline data of the location of the pipes that includes a field of the absolute 'height' (depth) of the pipes, and a separate digital elevation model of the area. I want to add z-coordinates to the pipelines. Is 'features to 3D from attribute the correct' tool to use to do this (selecting the feature of the height in meters). It just seems like the program would need more information than just the absolute height in meters, since it wouldn't know that the unit was in meters, for example.

Thanks for any information!

Hi Erin,

The Help on "Feature To 3D By Attribute (3D Analyst)" doesn't mention much about the units, but I assume it will be in the same unit as you input features (unless you have a vertical coordinate system defined).

Some of the settings are managed by the environment settings. For this tool the following settings may be relevant:
Output Coordinate System, Default Output Z Value, Z Resolution, Z Tolerance, Output Z Domain

Kind regards,
