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.
