Use the Adjacent Elevations By Reference command to set the elevations along a feature line, survey figure, lot line or 3D polyline, based on a grade, slope or elevation difference from points along another feature line. This command is similar to setting elevations in stepped offset, without first creating the offset.
Using this command, you can edit the elevations of one feature line and then update the elevations of another related feature line that exists alongside the first.
- Click
Find. - Select the reference object.
- Select the feature line or another object you want to edit.
Glyphs are displayed at each point that will be edited along the feature line, as well as yellow lines projected to the reference feature line, which display the location of the reference elevations for each point.
Only points that fall within the range of the reference object can be modified.
- Do one of the following:
- Enter the elevational difference. The elevational difference is applied between the reference point and the point on the feature line.
- Enter Grade and enter a grade. The grade is applied between the reference point and the point on the feature line.
- Enter Slope and enter a slope. The slope is applied between the reference point and the point on the feature line.
- Enter Variable. The Variable option steps along each point prompting for the elevation difference, grade, or slope. It does not insert any new points along the feature
The assigned elevation for the point is displayed at the command line.
