Guys,
I am trying to create a surface using the grading tool. I have a known top and a designed floor. I extended the floor surface out to meet the top breakline. I then use the grading tool to run a 3:1 down to the pond floor so I know where the true breakline is, but there is almost always a gap or two in my surface. It is usually less than a foot, but it has made my OCD kick in and I am going crazy trying to figure it out. I've traced of the breaklines, and the contours and addeded them to the surface to try and fix it, but that doesn't seem to work.
Any ideas?

It's hard to tell from the description. Can you share an image or, even better, a sample file?
Here is an image. Hope this helps in the explaination
There is no obvious gap in your TIN surface in your screen capture. Are you seeing a gap when you view it with Object Viewer or in a 3D view?
The Southern most green line points to the gap which is only .25'.
I see now what you are talking about. The black lines running down the slope is the surface boundary at the gap.
Without having your data it's hard to say what it is but a few things I would look for at that location are:
Elevation points, gaps in the grading (grading not applied to entire featureline), breaks in the featureline, any other anomalies that might influence the grading.
You might also try splitting the grading at that point, making a gap and adding a transition. Sometimes the software just has problems finding a solution.
I took your suggestion and broke the feature line, graded it and then did a transition. That seemed to fix that particular issue this time.
Thanks.
Just an FYI, you didn't need to break the FL to make the transition. In other words, a transition can be added to a closed grading applied to a closed FL.
Anyway glad to know you found a solution.
