INSTALLATION

1.Download the plugin from the Unity Asset Store

2.Download IfcConvert.exe version 0.7 for your operating system from https://ifcopenshell.org/downloads.html

3.Unzip the file you downloaded and copy the executable file "IfcConvert.exe" (Windows) or "IfcConvert" (Linux & Mac) to the IfcImporter folder in your project folder (on Windows by default to C:\UnityProjects\ProjectName\Assets\IfcImporter)

IMPORTING IFC MODELS INTO THE UNITY EDITOR

1.Manually drag the your IFC file into the Unity Assets folder in the editor

2.The conversion starts automatically. Please wait for it to finish.

3.Place the newly created prefab into the Unity scene from the Assets folder.

NOTE: The conversion process may require a large amount of memory! If your computer runs out of memory during the process, Unity may crash.

IMPORTING IFC MODELS INTO UNITY AT RUNTIME

IFC models can be imported into Unity at runtime using IfcImporter.RuntimeImport( string filepath ) which is documented in the README.

EXPORTING IFC MODELS FROM THE UNITY EDITOR

1.Select the root of an IFC GameObject in the editor.

2.Choose "Assets/Export selected IFC..." in the editor's top menu bar.

3.The IFC file will be saved in the project folder with the name "From_UnityEditor.ifc".

EXPORTING IFC MODELS AT RUNTIME

IFC models can be saved from Unity as IFC files using IfcExporter.Export() which is documented in the README.
