Problems with sample lines. Never created from existing polylines, sample lines point near alignment stray away from polyline I selected. Refer to image.
I can't give you the techical info on how or why but the sample lines seem corrupted. I have personally never recovered corrupted sample lines. I do know it does not happen often to me and I am pretty sure the last time I saw your issue it was on the 08 version, sample lines created from existing plines. I have a habit now of using alignments/profiles when I need sample lines/sections with deflection/bends from the CL alignment. With this approach I may never find out if this is a bug and it gets fixed...
