Converting 3D Poly to a Feature line

Hello all,

So I am attempting to create a simple grading daylight. I began with a 3D Polyline that has only 2 verticies. When I "Convert Feature Lines from Objects," it creates a feature line with 4 verticies. The 1st and last have the initial elevations from the 3D Poly, but the 2 new verticies seem to be pulling elevations off the surface below where I am working.

 

My questions are: 1) why are new verticies added? 2) can this be prevented?

 

I know that I can overwrite the slopes in elevation editor, but this seems like an unnecesarry extra step.

 

Thank you for your input

When you Create Feature Line from Objects, be sure you turn off the option to Assign Elevations.

Or if you need to assign elevations uncheck ie.PNG in the Assign Elevations dialog box.

Thank you for your comments. I will see when I run into it again if I can give a more concrete example as both of your suggestions I believe I was already doing.
