How to Best Setup an OpenRoads Project for a Major Strategic Design

Our project is about 70km long and will be broken up into a number of sections (about four sections). Each section will have multiple interchanges and possibly separate control lines.

We need advice on how to manage the dgn file structure for working with OpenRoads. The issues are:

  • How would we manage linking the alignments in each section for horizontal and vertical continuity. Should we have one single alignment for whole project so that if this changes all corridors and intersection update. Will the corridors update automatically?
  • How do you get the geometry of the corridors to line up? Can you link corridors to each other?
  • Do you keep interchanges in their own dgn?
  • Use of Civil Cells for building up an interchange. Is there an basic interchange Civil Cell?

Any advise would be much appreciated.
