Using 2010 with update 1 or whatever it's called these days, I'll just call it the first fix.
I've made three grading objects using "Grade to Relative Elevation" along a feature line. Then I've added a grading transition between them. This seems really unstable now, like making the wrong move makes the whole thing disappear...but what is strange is the feature line that is attached to the grading object that I have added into my surface remains, but there are only a few lines where the grading objects used to be, basically the line that seperates the different sections of grading.
Has anyone else experienced this phenomenon? There's no way to edit the grading again either, it has to be remade, because there is nothing to select.
