Command similar to pedit

I spent 20 years working with polylines in AutoCAD from version 1.16 to 2016 and relied heavily on the pedit command to see how a “curve” was constructed.

Is there any command that will allow me to step through the vertices, or has anyone developed a script that might enable similar functionality>


That doesn’t tell me what order the points are created in. I can use crvStart/crvEnd, but I’m looking for a way to step through the points from start to end, similar to pedit in AutoCAD.

Seems like a case for RhinoScript.

Hello- step through as in selection? If you select a control point NextU, PrevU should step back and forth along them. The ShowDir command will show you which way the curve currently ‘goes’.
