IfcCityJSON
|
|
===========
|
|
|
|
IfcCityJSON is a converter for CityJSON files and IFC. It currently only
|
|
supports one-way conversion from CityJSON to IFC.
|
|
|
|
PyPI
|
|
----
|
|
|
|
.. code-block::
|
|
|
|
pip install ifccityjson
|
|
|
|
Source installation
|
|
-------------------
|
|
|
|
1. :doc:`Install IfcOpenShell <ifcopenshell-python/installation>`
|
|
2. `Clone the source code <https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.8.0/src/ifccityjson>`_.
|
|
3. ``cd /path/to/IfcOpenShell/src/ifccityjson``
|
|
4. ``pip install .``
|
|
|
|
Usage
|
|
-----
|
|
|
|
An extended ifccityjson tutorial can be found on `the OSARCH wiki
|
|
<https://wiki.osarch.org/index.php?title=Ifccityjson>`_. Here's the built-in
|
|
documentation:
|
|
|
|
.. code-block:: console
|
|
|
|
$ python -m ifccityjson -h
|
|
|
|
usage: __main__.py [-h] -i INPUT [-o OUTPUT] [-n NAME] [--split-lod] [--no-split-lod] [--lod LOD]
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
-i INPUT, --input INPUT
|
|
input CityJSON file
|
|
-o OUTPUT, --output OUTPUT
|
|
output IFC file. Standard is output.ifc
|
|
-n NAME, --name NAME Attribute containing the name
|
|
--split-lod Split the file in multiple LoDs
|
|
--no-split-lod Do not split the file in multiple LoDs
|
|
--lod LOD extract LOD value (example: 1.2)
|
|
|
|
The example file that could be used is example/3D_BAG_example.json
|
|
|
|
.. code-block:: bash
|
|
|
|
python ifccityjson.py -i example/geometries.json -o output.ifc -n identificatie
|
|
|
|
The following geometries are implemented:
|
|
|
|
- [x] "MultiPoint"
|
|
- [x] "MultiLineString"
|
|
- [x] "MultiSurface"
|
|
- [x] "CompositeSurface"
|
|
- [x] "Solid": exterior shell
|
|
- [ ] "Solid": interior shell
|
|
- [x] "MultiSolid"
|
|
- [x] "CompositeSolid"
|
|
- [ ] "GeometryInstance"
|
|
|
|
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
