This model is from 2010, 10 years later in 2020, this model is still a good example of how we can work with rail or road models in BIM in the early design phase.
I was inspired by one of the lectures at the Autodesk University 2010. This model is only modeled by railings family in Revit Architecture.
I share this model with you to day and I appreciate if you send me link to your project examples of how you have worked with BIM for rail, road or urban design.
When Revit railings could be linked to terrain, this model has more opportunities than it originally had in 2010.
