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.</P><P></P><P>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?&nbsp;For instance,&nbsp;field 1 is the northern/eastern most end of the line and field 2 is the southern/western&nbsp;most end of the line?&nbsp;</P></BODY></HTML> Fri, 27 Mar 2020 15:26:18 GMT https://community.esri.com/t5/3d-mapping-questions/how-to-assign-start-and-end-elevations-for/m-p/864762#M837 StevenDouglas4 2020-03-27T15:26:18Z Re: How to assign start and end elevations for polyline features to 3D by attribute https://community.esri.com/t5/3d-mapping-questions/how-to-assign-start-and-end-elevations-for/m-p/1221257#M1074 <P>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.</P> Wed, 12 Oct 2022 19:57:32 GMT https://community.esri.com/t5/3d-mapping-questions/how-to-assign-start-and-end-elevations-for/m-p/1221257#M1074 MelissaSalich 2022-10-12T19:57:32Z Re: How to assign start and end elevations for polyline features to 3D by attribute https://community.esri.com/t5/3d-mapping-questions/how-to-assign-start-and-end-elevations-for/m-p/1398018#M1136 <P>At the moment am trying to figure the same thing.
