With the launch of Revit’s new 2021 platform there is a new Bridge Focussed category in the ‘Visibility Graphics Override’ that has been added to support bridge documentation and tie-in to Autodesk InfraWorks. Notice, in the image below, the new Filter list item called Infrastructure, showing the new features (highlighted).
Please note if you have Autodesk’s AEC Collection you have access to InfraWorks.
Also, under the Manage Tab, Settings Panel you will note in ‘Project Units’ there is also a new addition for Infrastructure too.
