Use the Gradient Extension By Reference command to edit a level by extending the gradient of a segment on another feature.
This command is used to apply the same gradient from a segment across a gap to a point on another feature line. For example, you can extend a gradient across an intersection.
The segment is highlighted and the gradient and slope are displayed in the command line.
As the cursor is moved along the feature line, it snaps to the nearest point that you can edit, displaying a yellow line from the reference point to the edit point.
The gradient, slope, level and distance to the point are displayed in the command line.
The assigned level for the point is displayed at the command line.
