I created an alignment and used the superelevation wizard to calculate the superelevation based on a rate table. After running the superelevation, I realized that I wanted the Radius Lookup Method to have a value of ‘Use nearest lower radius’ instead of ‘Interpolate radius’. I changed the value in the settings, but it does not get reflected into the alignments already created using the ‘Interpolate radius’ value. In Civil 3d 2010 there was a pull down box that allowed you to change this value under the superelevation tab in the alignment properties. I was unable to find a way to override this value in the superelevation curve manager/wizard/tabular editor in C3D 2011. Is there a way to change this value once created in C3D 2011?
