 # IFCCityJSON
-Converter for CityJSON files and IFC. Currently only supports one-way conversion from CityJSON to IFC. 
 
-## Dependencies
-- [IfcOpenShell](https://github.com/IfcOpenShell/IfcOpenShell) (also IfcOpenShell api is needed)
-- [CJIO](https://github.com/cityjson/cjio) (>=0.8, <1.0)
-
-## Usage of IFCCityJSON
-An extended ifccityjson tutorial can be found on [the OSARCH wiki](https://wiki.osarch.org/index.php?title=Ifccityjson)
-Following command will execute a conversion from CityJSON to IFC
-  
-    python ifccityjson.py [-i input file] [-o output file] [-n name of identification attribute]
-
-The example file that could be used is example/3D_BAG_example.json
-
-    python ifccityjson.py -i example/3DBAG_example.json -o example/3DBAG_example.ifc -n identificatie

-## Implemented geometries
-- [x] "MultiPoint"
-- [x] "MultiLineString"
-- [x] "MultiSurface"
-- [x] "CompositeSurface"
-- [x] "Solid": exterior shell
-- [ ] "Solid": interior shell
-- [x] "MultiSolid"

-## TODO
-- [x] CityJSON Attributes as IFC properties in 'CityJSON_attributes' pset
-- [x] Implement georeferencing
-- [x] Do not use template IFC for new IFC file, but make IFC file from scratch
-- [x] Create mapping to IFC for all CityJSON object types & semantic surfaces
-- [ ] Implement conversion of all CitYJSON geometries
-- [x] Implement conversion of all LODs instead of only the most detailed
