ICDAS supplies an add-ins software which causes Revit and Lusas to automate 3D models based on input

entered in an Excel file, or a text file (freeware Notepad++ recommended).

 

Both Excel and text input are equipped with expand/collapse functions helping you easily to keep overview

and focus only on the input you are working with. Further, with Excel input you can perform calculations in

other sheets, and link to sheet 1 for creation of the model. You can in this way keep many models input in

one Excel file as well. Only the model in sheet 1 is in interaction with Revit and Lusas.

 

You can even determine layout of the Excel input for a new model. It is a great advantage of using ICDAS

since you do not need training in new software user interface, in addition to Revit and Excel.

 

With ICDAS add-ins to your Revit, with a click you will get 3D elements automated in Revit, with positions,

dimensions and types written in the Excel file. You can undo Revit with Ctrl+ Z, update the input in Excel

and automate the model again.

 

It is also possible to automate the planning time to build the construction (4D) and the price (5D) based on

the existing input for quantities, materials, dimensions and additional input for time rate of wages.

This feature introduces in ICDAS in agreements with a predetermined client.


ICDAS BRIDGE has input for Arch BridgesCable Stayed BridgesConcrete Bridges and Steel Frame Bridges.



 


INPUT BRIDGE.c & INPUT STL.c 

 

There are two files for text input, INPUT BRIDGE.c and INPUT STL.c. It is recommended to enter input 

in Notepad++ in C format (freeware editor). Note that the text input is just a simple text file, not codes

in C-language. ICDAS choose C format just to use "#region" function to expand/collapse data for an easy

overview, as shown below.

 

 

 

Alternative Text

 

 

You can click on '+' to expand the contents inside a region. Press "Alt+0" to collapse all opening regions

to the main regions as shown above.

 

Advantages of the text input is that you can enter free text without problem in ICDAS. It is practical when

you directly can note some comments in input during discussion with your partners/customers.

 

 

INPUT Bridges Excel.xlsm

 

Using Excel input there is only one file where "Input Bridge" is on sheet 1 and "Input STL" on sheet 2.

 

Advantages of the Excel input is that you can calculated geometry, loads on bridge... in other sheets and

link to sheet 1 for automatic models creation in Revit and Lusas. Further, you can also expand/collapse 

data in Excel file in COB 2017.00R to keep an easy overview. 

 

Input data are described further in Geometry and Analysis link.

Deck cross section input


This section shows examples of input for the deck cross section.

The concrete deck cross section is 22480mm width, consisting of 2 traffic lanes of 3.6m + emergency lane of 3m on each
side of STLo. The top of deck has a constant slope of 2% from STLo to the edgebeams inner. The bottom of deck is
designed with 11 lines in form of double boxes. The depth of boxes measured at STLo is 4m which give a depth-to-span
ratio of 4%. Using ICDAS Concrete Bridges one can modify these dimensions in input, run Add-Ins to create a new proposal
in Revit.

The solid deck can be used as prestressed concrete with

curved cables 13C15 to 19C15. The upper concrete slab

of 1100mm yields good spacing for the curved cables

together with the main cables in the two big solid boxes.

The case of solid deck the depth 4m should be reduced

by moving the four bottom lines 3, 4, 8 and 9 up.

Alternatively, two big holes can place in the two solid

boxes to reduce the dead weight.

 

The box deck can be used as prestressed concrete with
straight tendons in the upper, the lower and the side
concrete slab, as shown to the right (the tendons are
not modelled).
