Please allow us to switch this feature line snap to site off? i have to trim all my feature lines that i want to offset by step. we model all our sites and because of this snap to site feature, 3 d modeling takes twice the time it should? Help??
I agree with your "wish." Many users would prefer that feature lines not look at each other. Just let me create it quickly. I know what I'm doing.
Until such time as that option is added, have you considered exploding your feature lines into 3D polylines? That would eliminate the annoying problems of intersecting feature lines. When you're ready to use stepped offset, just pick a 3d polyline, Civil 3D will turn it into a feature line, do your offset, then explode both. It's an extra step, but if grading is taking you twice as long because of the feature lines, I think this method would at least be better than that.
