Welcome to ICDAS Add-Ins for automatic models creation of Cable-stayed


This section (and sections on the left menu) is a brief introduction to

working with automatic model creation of Cable Stayed Bridges.

It describes the basic methodology and is not contained all ICDAS tools

and descriptions. All examples are generic for worldwide use and do not

conform to specific company standards. Refer to a ICDAS licence for

more details on all parameters and guides to your project.


To run CSB 2017.00R, you need the following software installed on

your PC/Laptop:


§         ICDAS CSB 2017.00R

§         Revit 2017 with Civil Structures 2015 (Revit Extensions)

§         Lusas Bridge V15.2-5 (also available on previous version)

§         Excel or Text editor (NotePad++ freeware code editor)


CSB models are satisfied ICT-notification of The Danish Building &

Property Agency about digital construction with object-oriented 3D

building models and exchanged IFC format.


CSB 2017.00R is a 3D parametric model allowing you to create

cable stayed bridges in short spans or unlimited long spans in

real Landscoordinate at the bridge site.

The corridors overpass and underpass should first be design in

AutoCAD Civil 3D or Bentley InRoads/InRail. This is the first big work

in determining the location of the bridge on site which is outlined in

a registered version of ICDAS BRIDGE. Once Civil 3D bridge site is

done, start Revit and run Integration with AutoCAD Civil 3D. You will

get the corridors overpass and underpass created in Revit. You can also

create the corridors in Bentley InRoads/InRail, and export to *.xml file.

Then in Civil 3D import this *.xml file to check the correctness of the

corridors in Autodesk product for further working on bridges in Revit.

The entire procedure is outlined in details in a registered version of




Once the corridors overpass and underpass are in Revit, you can run

ICDAS CSB 2017.00R to create deck, piers, abutments and bearings



By entering input in INPUT BRIDGE.cs and running ICDAS Add-Ins in

Revit, you will get 3D bridge model in Revit and a Lusas.cmd file. By

importing Lusas.cmd in Lusas, you will get a FEM model automatically.

Automations are summarized below.


Automatic 3D geometry model creation in Revit

§         Cables arrangements in harp, fan or semi-fan system

§         Streamlined box girder

§         Pylons in H-, A- or V-shape

§         Piers and bearings

§         Foundations


Automatic 3D FEM model creation in Lusas

§       Geometric points, lines, surfaces of the bridge as Revit model


§       Detailed shell elements for the streamlined box girder

§       Cables in harp, fan or semi-fan geometric lines

§       Pylons in geometric lines


You can also create LUSAS model directly without Civil 3D and Revit

when the corridor overpass has a straight alignment, which is often

the case of cable supported bridges passing the water underpass.


See list on the left for further information.
