convert polylines to 3d polylines without creating a surface

[Anonymous]

hello everyone, 

I would like to transform 2d polylines which pass near the elevation points to 3d polylines by applying the z of these points . is there a way to do it without creating a surface ?

think you for helping me.

Hi @Anonymous, would it be useful to create a 3D Polyline or a Feature Line along those points?  

If the points are COGO points, use the option on the image to create separate lines, and then, you can join and convert them to create a 3d poly or a feature line.

I hope this helps, best regards!
