IFC data extraction and read it

josepht21 — Sun, 13 Dec 2020 16:50:46 GMT

Hi everybody! I am new in the IFC world and I am trying to export a model as an IFC4 file and then use that file to order it as a csv of information containing the coordinates of the column (start and end coordinate), the contour definition of a slabs, walls and openings.

Is there anything open source that I can use or a good tutorial to get started? I can't seem to find a lot of examples similar to what I need to do. I am using C# by the way.

Thanks in advance.

You have your model in Revit? Then no need to export it to IFC.

Then you could use Dynamo (visual scripting) to extract locations of the columns and export that dat to csv or Excel.

If you are familiar with C# you also could use the Revit API to creat an add-in which performs the same task.

Thanks for your response, I actually need the IFC path because of what I want to do.

IFCs are simple txt files. You would need to analyze how the data is exported to the IFC and then read that dat from the IFC. You could ismply start by exporting a simple file to IFC and check how the dat i converted to IFC format.

You also could visit the Buildingsmart website and read about how the different schema is working.

Other good source is the Revit IFC GitHub site. This has source code about how the Revit IFC addin exports data from Revit and written in C#.
