- [Instructor] Sometimes you want to move a feature line…up or down in the z-axis,…preserving the slopes and elevation relationships…between its points.…Let's take a look at how that's done.…I'll select this feature line in the drawing,…and I want to point out that there's…an elevation point here in the middle…that shows a pretty prominent high point.…And let's just say I want to raise or lower this feature line…and preserve that relationship.…I want to keep this high point where it is,…I want to hold this slope and this slope,…but I want to raise everything up.…So, all of the elevations are going to change…relative to one another.…
Not a problem, all I have to do…is launch the Raise/Lower command.…And if I want to raise the feature line up 10 feet…or whatever value, I simply enter a positive value,…so I'll type in 10 and press Enter.…If I want to lower the feature line,…I simply type in a negative value, -10,…and it's raising and lowering that feature line…while preserving the elevation and slope relationships.…
