BIM model (Revit Bridge Geometry)
Creation of the 3D bridge in Revit is an extension of terrain model just created from Civil 3D. The horizontal alignment, longitudinal profile and slopes of cross section of the pavement overpass are created from Civil 3D, and can not be changed in Revit, unless you redesign the corridor in Civil 3D file. From this point on, you will work with Revit Bridge using parametric families of the bridge's components. In this context you will enter input for the family files. Revit will prompt windows up for you to select type and enter dimensions of the deck, the edgebams, the abutments, the piers and the bearings. Once Revit has been successfully created these families, you will get a 3D bridge incl. terrain surface as shown in Figure 1 below.
From Revit 3D model you can (as shown in Figure 2, 3, 4, 5...): › create Revit Views for documentation (drag to sheets)
› use 3D Section Box and 2D sections for the details (dimensions, elevations, annotations and so on)
› modify a component in bridge in family file (*.rfa) and load it into project file (*.rvt)
› when a bridge component is updated, the 3D model is accordingly updated, also all associated views and sheets
› use Revit automatic creation of documentation You will work only in one project file (*.rvt) including all views and sheets. |
