Civil 3D has a robust set of tools to help you edit feature lines.
00:09
Use these tools to easily adjust individual or multiple elevation and slope values.
00:16
In this example, a pond is already created in the drawing.
00:20
Select the top feature line, then right-click in the drawing area and select Elevation Editor.
00:29
In the Grading Elevation Editor dialog, view the elevation points.
00:35
To edit all points at once, simply select all rows in the table, and in the active Elevation(Actual) cell, enter 636.
00:46
All points update.
00:49
You can also access elevation tools from the ribbon.
00:53
Select a feature line, and in the contextual ribbon, Modify panel, click Edit Elevation, if needed, to turn on the display of this panel.
01:04
In this example, a weir is already created on the left side of the pond.
01:10
To add elevation points, select Insert Elevation Point.
01:15
In the drawing, snap to and select the endpoint where the upper polyline and the feature line meet.
01:23
At the command prompt, enter the elevation 635.
01:29
Repeat these steps for the lower polyline.
01:32
Press ENTER to complete the command, and then open the Elevation Editor to see the two added points.
01:42
To quickly edit elevations and slopes, from the Edit Elevation panel, select Quick Elevation Editor.
01:51
In the drawing, hover the cursor over any of the vertices on a feature line to view its elevation.
01:59
Hovering between two elevation differences displays the slope, or grade.
02:04
Click to edit the displayed value, then enter the desired elevation or slope at the command line.
02:12
Next, in the drawing, locate the closed polyline already created in this example.
02:19
To turn it into a feature line, in the ribbon, Home tab, Create Design panel,
02:26
expand the Feature Line drop-down and select Create Feature Line from Object.
02:33
Select the polyline, and in the Create Feature Lines dialog, in the Style drop-down, select Standard.
02:42
Click OK twice.
02:45
Select the feature line, and in the contextual ribbon, select Add to Surface as Breakline.
02:54
From the Select Surface dialog, select Create Surface.
02:60
In the Create Surface dialog, click in the Name field, and type “Parking”.
03:06
Click in the Style field, and then click Browse (…).
03:12
In the Select Surface Style popup, expand the drop-down, and select Contours (Background).
03:20
Select Edit.
03:22
In the Surface Style – Contours (Background) dialog, click the Major Contour color.
03:28
In the Select Color dialog, select red, and then click OK.
03:34
Follow the same steps to set the Minor Contour color to cyan.
03:39
Click OK 4 times to close all but the Add Breaklines dialog.
03:46
Here, under Supplementing factors, enter a distance value of 2.5, and then click OK.
03:54
The feature line is added to the surface.
03:57
Before adjusting elevations, make sure the surface is set to rebuild automatically.
04:04
In the Toolspace, on the Prospector tab, expand Surfaces.
04:10
Then, right-click Parking and select Rebuild - Automatic.
04:17
Now, select the feature line, and in the contextual ribbon, select Quick Elevation Editor.
04:25
Using this tool, you can easily adjust elevations and slopes by typing them into the command line.
04:32
Hover the cursor over the bottom corner to display the elevation, click, and then enter a new value, such as 746.25.
04:45
Next, hover over the middle of the bottom line to display the grade, click, and enter -4.
04:53
Continue by setting a grade of 4 up the left vertical line at three locations between the points,
05:00
then enter a grade of 10 for the left top line.
05:08
To set multiple grades between two selected points, in the Edit Elevations panel, click Set Grade/Slope between Points.
05:18
In this case, select the left-most point on the top line, and then press ENTER to accept the elevation.
05:25
Then, select the right-most top corner point, and enter a value of 5.
05:31
Hover the cursor over different locations between the selected points to see the applied 5% grade.
05:41
To raise the entire feature line, select it, then right-click and select Raise/Lower.
05:50
On the command line, enter the amount to raise or lower it by, such as 1.25 feet.
05:58
Hover the cursor over the bottom right-corner to see that the elevation is now 1.25 feet higher.
06:06
To adjust the entire feature line to drape upon the surface, from the Edit Elevations panel, select Elevations from Surface.
06:15
In the Set Elevations from Surface dialog, select EG for existing ground, then click OK.
06:25
Select the feature line, and press ENTER to complete the command.
06:30
Open the Elevation Editor to see the adjustments to the elevations.
06:36
As you have seen, the elevation tools offer many ways to edit the elevations and slopes
