When processing a corridor with Point Controls using Secondary Alignments, the Add Exterior Boundary settings recognizes the end point location of each section, but if there is a secondary alignment inside of the end point and due to the bend it creates, the point can fall outside of the boundary. When this happens, its contours and surface limits get clipped. This happens sometimes at the limits of the corridor but is exacerbated when working with a corridor that has cross streets and the templates through the cross street area stops at the edge of through roadway.
On my current project, the back edge of sidewalk where it approaches the intersections is frequently curved and the curves start before the curb returns of the cross streets. So the end of the curved sidewalk features often end up outside of the exterior boundary limits. This also often occurs on the curb return corridors that are designed to fit into these areas.
I am having issues getting a single composite surface to triangulate when I try to make one surface from all of the corridors, plus while I prefer to not use transverse features on my mainline, I frequently need them on the cross street corridors, This also prevents me from making a combined DTM as there is no way to only create transverse features on individual corridors while not creating them on others when processing multiple corridors into a single surface.
I wonder, are there similar issues in Ss3+?
