To Draw Straight Segments of Feature Lines

1. Click Home tabCreate Design panelFeature Line drop-downCreate Feature Line Find.
2. In the Create Feature Lines dialog box, specify a site, an optional name, and an optional style for the feature line. Select a layer and note that the option to use a selected entity layer is disabled. Click OK.
3. Select the start point for the line. You can use Osnaps or transparent commands to snap to existing geometry.
4. Specify the elevation for the start point by doing one of the following:
   • Enter an elevation at the command line.
   • Enter Surface (S) and select a surface from which to obtain the elevation.
     Note: If there are no surfaces in the drawing, the Surface option is not available. If there is only one surface in the drawing, that surface is selected automatically.

   The following prompt is displayed:

   Specify the next point or [Arc]:

5. Select the next point.

   The following prompt is displayed:

   Specify grade or [SLope/Elevation/Difference/SUrface/Transition] <0.000>:

   Note: See To Draw Curved Segments of Feature Lines for information about the Arc option.
6. If you wish to specify each elevation point as you create points, skip down to Step nine. To continue drawing points without establishing the elevation until the end:
   • Enter the Transition command.
   • Create a new point. When Transition is selected, as each subsequent point is created the elevation prompt will default to Transition.

     Transition or [SLope/Elevation/Difference/SUrface] <Transition>

7. Press Enter to continue drawing another point(s) without specifying the elevation.
8. After creating points, select and enter the desired keyword to specify the elevation, grade, slope, or elevation difference. If you end the command while still in the Transition prompt, you will be prompted to specify an ending elevation.
9. Do one of the following to establish the elevation of the second point:
   • Enter a grade. The grade is applied to the segment between the first and second points.
   • Enter Slope (SL) and enter a slope. The slope is applied to the segment between the first and second points.
   • Enter Elevation (E) and enter an elevation. The elevation is applied to the second point and the grade of the segment between the points is calculated.
   • Enter Difference (D) and enter an elevational difference between the first and second points.
   • Enter Surface (SU) and specify a surface from which to obtain the elevation of the second point.
10. Specify the next point on the feature line by doing one of the following:
    • Select the next point in the drawing.
    • Enter Length (L) and enter a length. When you use this option, the direction of the segment is assumed to be the same as the end of the previous segment.
11. Specify the elevation of the point using the options described in Step 6.
