Bridge layout 2D from 3D Model 
3D model makes bridge easy to understand, but we need 2D drawings with dimensions to build the bridge. Creations of 2D-sheets are semi-automatic because the users need to choose the views with stations, coordinates, dimensions, levels and so on. They are varying from bridge to bridge. E.g. large bridge and small bridge need different scales to fit into the 2D sheets. However, using ICDAS BRIDGE Manual takes only
20-30 minutes to created the four basis sheets as
shown to the right for a simple slab bridge. The
sheets themselves are loaded from ICDAS sheet
family automatically.
Showed to the right are simple layout of 2D-sheets with 2D models created automatically from the 3D model. 3D rendering shows a slab bridge from which the 2D-sheets are documented. Plan Elevations shows the bridge level increased
434mm toward south with a slope of 1.67% (Station
Increment Report.htm for 1m step of station,
elevation from Civil 3D is not shown here). The
underpass has constant elevation of 44300mm.
Substructure Dimensions shows lands coordinate in the four corners of the foundations (in mm). From which and the given dimensions there are geometrically information enough to build the foundations and abutments at the site in XY-Plan. North and South shows elevation Z-Coordinate at the
two corners of foundation of an abutment. From which
and the given heights there are information enough
to build the foundations and abutments at the site in
vertical Z-direction.
