That must be possible to modify Infraworks bridge elements in Revit unstaid of Inventor. Civil peoples doesnt know the mecanic softwares of Inventor. That is a major problem for us. Maybe a connected and friendly user interface in Infraworks can be the solution.
Take a look to the direct competitor of Bentley Openbridge workflow that is easyer to modelise bridge element to add to the model. Thanks for your support.
