Surface Boundary Blows

[Anonymous]

Getting some interesting boundary blows, please see attached.

The odd shapes are outside the daylight line.  They follow a straight-line around the daylight limits (see third attached file), apparently triangulating unwanted areas.  I've used a corridor shrink wrap for the surface boundary.

What is the best bet?  I'd rather not draw a polygon along the daylight line and use it as a surface boundary, since it could change.  Setting a max triangle length in the surface does not seem to provide a desired result.

Any advice appreciated.

Thx,

It looks like the boundary failed for some reason.  When you rebuild is there an error message for this?  Sometimes it will have an option to zoom into the point where it failed.

Your best option is probably to go old school and build the boundary manually by selecting the feature lines and station ranges to want to use for this.
