Proximity Breakline Stop Triangulation?

Hi, I've watched a few videos on Youtube about using a prox. breakline to stop triangulation between points and for some reason it never seems to work right when I try to use this method to clean up my surface.  I don't know if I'm missing a step or my machine is configured in a way where it doesn't pick up the trianglation because it's at a different elevation persay than the midpoint between the two points.  

 

I feel like it's just not working like it should.  Maybe I don't quite understand exactly how it works.

 

Anyways, I provided a test file which I made a few polylines with elevations, then snapped points along them to make a surface out of.  I didn't want the triangulation to occure through the 'orange' line, so I added to the surface as a prox. breakline, but it still triangulates right past it in some cases and avoids it in others.

Turn the orange line into a "Feature Line". Make sure to assign elevations at the elevation you wish. once the polyline has been turned into a featureline you can add it to your surface as a breakline. This should stop the TIN from going through the oragne line.
