Good day, I am using Civil 3D 2014 and I am having a problem with missing data on my band that shows the offset levels generated from a surface profile. I have created a corridor with a surface and instead of using offset alignments to get my left and right edge levels, I have used offsets in the profile wizard for the left and right edge, the levels of which should be generated from the corridor surface. I am still missing elevation data from a specific stake/station value on my profile band for the left edge. Things I have tried: 1. Adding extra points from the point at which the profile ends. 2. Regenerating the surface from scratch. 3. Regenerating the profile from scratch. None of the above have worked, I have tried other things none of which solved the problem either. Short of starting the drawing from scratch is there any solution to this. I have tried to add pictures, but it doesn't want to accept the upload. Your assistance is greatly appreciated.
