Plotting Special Ditches in Sheets

There are a couple of methods, but one that seems pretty commonplace is to project the special ditch profiles onto your mainline alignment. A word of caution: if you use a feature definition for the special ditch profiles that has annotation definitions associated, it will place VPI and slope labels at much more regular intervals than you likely intend. This is because of how the software projects profiles from one element to anotehr. You can avoid this by not annotating those automatically, or using a feature definition that has no annotation associated with it. 

Another method is to actually store the ditch profiles on the mainline itself and then project them out to the ditches. This eliminates the issue with the improper annotation but can cause other downstream effects that you need to watch out for.
