Simple c# classes to read and write a file in the format IFC 4 XML.

Start using Ifc.NET with NUGET (https://www.nuget.org/packages/Ifc.NET).
To install Ifc.NET in your .NET application, run the following command in the Package Manager Console in Visual Studio: "Install-Package Ifc.NET"

Your solution must run on the .NET Framework 4.5.

To read a file, please follow this steps:


Download an ifcxml sample file from here: https://github.com/CAFM-Connect/Ifc.NET/tree/master/src/SampleReader/SampleFiles and copy it to your computer.

Paste this code snippet into you code:

string Testfile = @"C:\Tmp\MyFirstIfcFile.ifcxml";
Ifc4.Document ifcDocument = Ifc4.Workspace.CurrentWorkspace.OpenDocument(Testfile);

Adjust the path to the file to the location, where you copied the sample file.

Run your application in Debug and look at the object ifcDocument.

var header = document.IfcXmlDocument.Header;
header.Organization = "My Organisation";

Add new Site

var ifcSite = document.Project.Sites.AddNewSite();
ifcSite.LongName = "A";

Add new building

var ifcBuilding = ifcSite.Buildings.AddNewBuilding();
ifcBuilding.LongName = "B";

Add new building storey

var ifcBuildingStorey = ifcBuilding.BuildingStoreys.AddNewBuildingStorey();
ifcBuildingStorey.LongName = "C";

Add new room

var ifcSpace = ifcBuildingStorey.Spaces.AddNewSpace();
ifcSpace.LongName = "D";

Save the IFC file

document.Workspace.SaveDocument(ifcFullName);
