How to Delete Intersections in AutoCad Civil 3D

You can delete an intersection object, erasing it from the drawing and removing it from the Intersections collection in the Prospector tree.

When you delete an intersection object in the drawing, the following are deleted:

• the intersection object, and its label, in the drawing
• the intersection object in the Intersections collection in Prospector
  

The following components associated with an intersection object are not deleted when you delete an intersection object:

• the following 2D geometry components associated with the intersection object: intersecting alignments, offset alignments, curb return alignments
• the following other components associated with the intersection object: offset profiles, curb return profiles
• If you created a new corridor object inside the intersection area, this corridor object is not deleted when you delete an intersection object. You must delete this corridor object manually, if desired.

You can use the following methods to delete an intersection object:

• In the drawing, select the intersection object, and delete or erase it.
• If you delete one or both of the intersecting alignments that create the intersection, then the intersection object is automatically deleted.
• In the drawing, if you move one or both of the intersecting alignments that create the intersection so that the alignments no longer intersect, then the intersection object is automatically deleted.
