How to create Node to do the action of an existing Civil 3D command

Hi @jbrunkhorst,

Some more info here:

Commands without dialog box in Civil 3D

is there any way of executing commands in civil 3d without opening the standard dialog boxes? and thus completing the command automatically with the standard settings?

In a nutshell, some commands have a pure command line version and a UI version, but not all of them. The particular command that you mention does not have a command line version.

I think you have a few options. The first is using one of these nodes to get a “draped” polycurve on a surface. From there, you could create a 3D polyline from the polycurve.

If you’re using Civil 3D 2025, there is this node specifically for feature lines.
