I have a similar problem when creating sections. If I try to create a single section view, the elevation limits are -10 and 10. It also happens when I try to create multiple views. Some will be ok, others will be at strange elevations and offsets. I'm not able to edit the elevations. I redraw the sample lines multiple times, I've tried giving the polylines elevation before using them for a sample line, changing the starting and end points, but I've not found a solution. Any ideas?
