However, do an interpolation with bounding cross sections that have more than 255 points each, and you will have interpolated sections with more than 500 points. This is normally not a problem, as long as you don’t exceed 500 points (the maximum allowed for any cross section in HEC-RAS. ![]() It’s not too uncommon for a model created in GIS to have multiple hundreds of cross section station elevation points.
