On most road and rail jobs, we’re never dealing with a single alignment. There’s usually a mainline plus ramps, offsets, adjacent tracks, service roads, or platform lines that all need to behave together vertically.
That’s where problems often creep in.
Horizontal relationships are usually under control, but vertical geometry between parallel alignments is harder to keep consistent as designs evolve. A small change to one profile can quietly introduce grade breaks, clearance issues, or mismatched transitions elsewhere—often without being obvious in plan or long section.
Bentley’s Project Vertical Geometry Between Alignments workflow is designed to manage exactly this scenario.
Instead of manually re‑creating profiles, this approach allows vertical intent to be projected from one alignment to another in a controlled, repeatable way. When used properly, it helps keep parallel profiles aligned with the same logic-rather than relying on visual checks or manual edits.
The real value isn’t just speed. It’s about:
- Reducing rework when changes inevitably happen
- Avoiding subtle inconsistencies that only show up late
- Making authority reviews easier to defend
- Letting engineers focus on design decisions instead of redrafting
The video linked below walks through the workflow step by step and shows how Bentley handles this natively within its alignment and profile tools.
If you regularly work with multiple parallel alignments in MicroStation, OpenRoads, or OpenRail, this is one of those features that’s worth understanding properly. It can save hours-and avoid some painful surprises later in a project.
