I am trying to set up a new network and I have created a street center line file that includes as one of many fields the to and from elevation for the points, but when I try to include them as part of the build it won't list the columns so that I can pick them. What do I have to do to the elevation fields to get them included? I had extracted the data from a dem, so the column names are Rastervalu and Rasterval_1. The fields do show as numeric datatypes. Any help would be appreciated.
