can lines be told their elevations from a surface?

[Ryan Ease]

I have a bunch of 2d lines I'd like to follow a surface as their elevation reference. Is there a simple way to do this or do I have to draw all the lines again in 3d?

Convert them to feature lines. When converting them, there is an option to get the elevations from a surface. If they need to be 3D polylines, you could then explode (I know, can you believe I'm actually suggesting this?) back down to 3D polylines.

Like Brian suggests, create Feature Lines, then explode.

Grading>Create Feature Lines from Objects

Make sure you check the "Assign Elevations" box checked, and choose the surface or grading you wish to obtain elevations from.

If you do a lot of lines at once, this process can take a bit, so be patient.

Also, when working with Feature Lines, Save early, and save often.

Cool, I new there had to be a way. Thanks.
