I've already done 5 roads in this project with no problems. I simply modified the profiles and re-ran them after going through all the steps. I have 2 roads that for some reason won't work for me. I keep getting an error saying "error: cannot create cross section topsurface breaklines". Any ideas? I've tried widening/narrowing the sampling swath, I tried re-creating the template. I'm at a loss as to what to do. Thanks.
