Installation[edit]
Install dependencies: CJIO & IfcOpenShell-python
IfcCityJSON is a python library that is based on two libraries: IfcOpenShell (for IFC manipulation) and CJIO (for CityJSON manipulation). These need to be installed first. CJIO (python 3.6+ only) is installed with:
python -m pip install cjioThe IfcOpenShell-python library is needed (with API included). Unfortunately, the API is not yet shipped with the releases on www.ifcopenshell.org/python, but this IfcOpenShell commit has the API included. Copy this folder to your python site-packages folder, that is found under your python folder/Lib (for example: 'C:/Users/user/AppData/Local/Programs/Python/Python39/Lib/site-packages').
Usage[edit]
Now both packages are installed, IfcCityJSON is ready to be used. Download the repo https://github.com/IfcOpenShell/IfcOpenShell and navigate to src/ifccityjson. Open your command prompt in this directory. The following command will execute a conversion from CityJSON to IFC.
python ifccityjson.py [-i input file] [-o output file] [-n name of identification attribute]So, for example, you would like to convert the file C:/Users/user/Documents/3DBAG.json, where the naming attribute is 'identificatie' this is possible with the following command:
python ifccityjson.py -i C:/Users/user/Documents/3DBAG.json -o C:/Users/user/Documents/3DBAG.ifc -n identificatieThis will provide an IFC file 3DBAG.ifc that can be opened with your favourite IFC viewer!
