Civil 3D has a robust set of tools to help you edit feature lines by adjusting the geometry of these lines.
00:11
Start by creating a feature line in your drawing.
00:14
Select the feature line, and in the contextual ribbon, in the Modify panel,
00:20
click Edit Geometry to toggle the display of this panel.
00:24
You can edit feature lines using these tools.
00:27
First, insert points of intersection on a feature line.
00:31
From the Edit Geometry panel, click Insert PI,
00:35
and select a point in the drawing.
00:37
In this case, snap to a contour line.
00:41
The command window prompts you to specify the elevation or use the Surface elevation.
00:46
Because a contour was selected, the elevation of the contour displays.
00:51
At the command prompt, press ENTER to accept.
00:55
Press ENTER again, and then ESC.
00:58
The PI now appears in the drawing.
01:01
To remove the PI, in the Edit Geometry panel, simply click Delete PI, and then click the PI in the drawing.
01:10
Next, review some of the tools in the Edit Geometry panel and select Fillet to add a fillet at point D in this example.
01:18
The command window prompts you to specify a corner or Radius.
01:23
In this case, select Radius and enter 100.
01:28
Hover the cursor over the desired fillet location in the drawing—here, point D—and a preview of the curve displays.
01:36
To adjust the curve, in the command line, click Radius, and this time, enter 250.
01:44
In the drawing, click the location for the fillet, and then press ENTER to add the curve.
01:50
To edit the curve, from the Edit Geometry panel, select Edit Curve.
01:56
In the drawing, select the curve to open the Edit Feature Line Curve dialog box.
02:01
In this example, in the Radius field, enter 200.
02:06
Click OK, and the curve adjusts.
02:09
Use the Create a Feature Line from Stepped Offset tool when adding feature lines that have a horizontal and vertical offset at the same time.
02:18
In this example, to create a 5-foot bottom ditch from the feature line in the drawing,
02:23
select the feature line, and then in the Edit Geometry panel, select Create a Feature Line from Stepped Offset.
02:30
On the command line, to specify the offset distance, enter a value of 2.5.
02:37
Next, specify the side to offset.
02:42
In this case, click north of the existing feature line.
02:45
At the command prompt, enter an elevation difference of 0.
02:49
The offset line appears above the original feature line.
02:53
Select the original feature line again and repeat the steps, but this time, specify the offset side by clicking south of the feature line.
03:03
The offset line appears below the original.
03:06
Repeat twice more: select the top feature line, enter 12, click north of the line, and enter 4;
03:16
then, select the bottom line, enter 12, click south of the line, and enter 4.
03:24
To view the lines in 3D, select the feature lines you just created in the drawing.
03:30
Then, right-click and select Object Viewer.
03:34
In the Object Viewer, expand the View drop-down and select SE Isometric.
03:40
Notice that you have the start of a ditch.
03:43
Select all the ditch feature lines, and in the contextual ribbon,
03:47
click Add to Surface as Breakline.
03:51
In the Select Surface dialog, click Create Surface.
03:55
In the Create Surface dialog, in the Name field, type “ditch”.
04:01
Click in the Style field to display the Select Surface Style dialog,
04:05
and in the drop-down, select Borders & Contours & Slopes.
04:10
Click OK four times to close the dialog boxes.
04:14
Now, rotate and pan the view to see the contours depicting the ditch.
04:19
Using the Edit Geometry tools, such as Insert PI, Fillet, and Edit Curve,
04:25
you can easily adjust feature lines and create the components you need for your project.
