Are your projects using Federated models for design/sighting/integration/approvals?
BIM Nav allows inexperienced 3D MicroStation users to explore project models with confidence. The dynamic integration of project chainage data provides true distances, supporting design integration activities and assessments.
For BIM Nav to function the referenced rail elements need to be a continuous line string with the CAD element direction aligned to normal direction of traffic. Chainage is calculated from the referenced project chainage which consists of a continuous line element.
