Chapter 5 Working with Surfaces

180

The following illustration shows a surface triangulation that does not

accurately interpolate the surface elevations, as shown by the cross

sections cut from different locations. By defining breaklines, you can

control how the triangulation will occur with regard to abrupt

changes in the terrain.

You can define three types of breaklines.

■

Proximity breaklines: Defines breaklines using the points in the

database nearest to the breakline that you draw. You do not have to

snap to exact points.

■

Wall breaklines: Defines the elevations of a wall-type object on

both sides of the wall. For example, triangulation is linked to the

bottom of the wall on one side, and then begins again from the top

of the wall on the other side.

■

Standard breaklines: Defines the breaklines using the exact points

or polylines that you select.
