Convert a 3D polyline to a 2D polyline

[JeffPaulsen]

Is there a way to convert a 3D polyline to a 2D polyline in Civil 3D? If not, does anyone have a free lisp routine they would be willing to share?



I know there are third party packages that do this but money is a little tight right now. Plus I can just go back to LDT but I am trying hard to avoid that.

Thanks but Flatten does not make 2D polylines. It only changes the elevations of the 3D polylines.

Thanks Sinc. Worked great. After converting them to 2D polylines I just used Properties to make them all elevation 0.

Why are the "polyline utilities" not on the Ribbon?

They are there.

Hit the Modify tab, and then expand the Design
panel.
