This product idea proposes an enhancement to ConceptStation that would allow the sideslope end conditions on multiple roadway alignments to target each other to prevent overlapping slopes. Currently, this is only possible with the intersection, roundabout, and bridge creation tools. However, if two alignments are in close proximity to each other (parallel roads), their sideslopes will not target each other. For example, of modeling a divided highway with two independent alignments, their inner slopes will not target each other to form a grass median.
