Any surveyors in the FDOT Forum here? Two concern/question topics:

Shawn,

Not a surveyor (so I don't have an answer), but I share your frustration. We see the issue with the b-spline curves most often while generating the existing features models. As you noted, we are forced to either approximate the curve with an arc, or use the facet tool. 

In Connect, FDOT is still supporting the GDTMRD file as a valid filename. I have been making a separate GDTMRD file on my projects, backing up the SURVRD, and removing the terrain model from the SURVRD for precisely the reason you highlighted. This also helps with modeling efforts, I have noticed. Any little performance gains go a long way. 

Thanks eddiegiese !  Just ran across another this week in ORD.  Fortunately for this project, areas where it matters are few and use a constant sawcut offset from BL.  I know it's tough bridging the gap between the surveyor mind and engineer.  I've had the opportunity to work for both and understand how this can become an issue on both sides.
