Further exploration:
Notice that, along some portions of the polylines, the
surface triangulation incorrectly crosses the breakline. This happened because
the surface contours also act as breaklines. The new breaklines are not added
because the contours are already acting as breaklines, and the current surface
setting does not allow more than one breakline to affect the surface at a given
point. To override this behavior, you can perform any of the following tasks:
■
Build the surface with contours and breaklines:
In the Surface Properties
dialog box, on the Definition tab, expand the Build collection. Set Allow
Crossing Breaklines to Yes, and then set Elevation to Use to Use Last
Breakline Elevation at Intersection.
