Autocad Civil 3D: Modify the Cutting Plane

When you create a section view, you determine the position of the cutting plane. The appearance of the resulting section line is controlled by the section view style.

Once the section has been created, you can grip edit the cutting plane similar to how you grip edit a polyline. When you modify the cutting plane, the section view updates to reflect the changes.

For example, in the exercise file you can see several views of a gear assembly. When you click to select the section lines, you see a number grips. You can use those grips to modify the cutting plane.

The grips look very similar to the grips you see when editing a polyline, and if you pause the cursor over a grip, you see an extended tooltip that shows the options available for modifying that particular grip.
