Equalize feature line grade between endpoints

[robert06]

Is there a command, a lisp maybe, to equalize feature line grade between it's endpoints?
Using 'set feature grade' command requiers cumbersome clicking and draging cursor between endpoints which I believe could be avoided.

Hi @robert06,  If I understand the question correctly you can select a feature line an right click and from the list select elevation editor. Then in the panorama that opens click the top station and hold the shift key and click the last station to select all stations. Then click the flatten grade button and select constant grade and hit ok.

Interesting, I've always felt the elevation editor was cumbersome and the setfeaturegrade tool was simple and gave you a nice graphical depiction of exactly from where to where the edit would take place.  Having the feature lines labeled with elevations and slopes really gives you a nice visual of what is going on rather than trying to correlate rows in the elevation editor with what is on the screen.  The Quikeditfeatureelev and the Setfeaturegrade are my two main go-to tools for feature line editing.

@user181is correct. When you first enter the elevation editor, and no points are selected, clicking on the "flatten grade" button will act on the entire feature line without selecting all points. If a point or points are currently selected, [Ctrl]+[A] will select all points.

Automation opportunities are limited. You could use a shortcut or lisp to invoke "AeccGradingElevEditor" that would open the Elevation Editor in the Panorama, if a feature line was pre-selected. Once open, there does not seem to be any keyboard or programmatic interface.

I was not aware of 'flatten grade' being there, as I have tried not to use elevation editor too often, have gone for 'Quick elevation edit' and 'Set feature grade', which I believe are still quicker than opening elevation editor, just like McCall stated. But yes, it's an option and leaves me wondering why there is no dedicated command for this.

@MMcCall402 - it does give you a visual cue. If you select lines in the Elevation Editor, it will highlight the vertices chosen with a green triangle. Or are you talking about something more visual than that? (e.g. a long section with highlights?)

Not looking for visualization in this case rather than just flattening the grade with a single click when the endpoints' elevations are set.

Hippe013 just lisped it as 'StraightGrade'

Select the Grade/Slope between points. Select your First Point and then your Second Point. Then choose the "Elevation" or "Grade"option in side the command. If you select elevation CAD will set all the grades to the average grade. If you hold "grade" cad will change your end elevations.
