+parsing support is provided for [IFC2x3 TC1], [IFC4 Add2 TC1], IFC4x1, IFC4x2, and [IFC4x3 Add2]. Extensive geometric support
 is implemented for the IFC releases [IFC2x3 TC1] and [IFC4 Add2 TC1]. Extending with support for arbitrary IFC schemas
 is possible at compile-time when using C++ and at run-time when using Python.

-In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to

 # bcf

-A simple Python implementation of BCF.
-Manipulation of BCF-XML is available via `bcfxml.py` and manipulation of BCF-API
-is available via `bcfapi.py`.
-
-It tries to support BCF-XML version 2.1 and 3.0, and BCF-API 3.0.
-
-## bcfxml
-
-The `bcfxml.load` function lets you read a BCF-XML file.
-It takes care of using the right version based on the "bcf.version" file contained in the BCF package.
-
-The BCF files are extracted and parsed on-demand, and edits are stored in memory until you call the `save` method.
-
-```python
-from bcf.bcfxml import load
-
-# Load a project
-with load("/path/to/file.bcf") as bcfxml:
-    project = bcfxml.project
-    print(project.name)
-
-    # To edit a project, just modify the object directly
-    bcfxml.project.name = "New name"
-
-    # Get a dictionary of topics
-    topics = bcfxml.topics
-
-    for topic_guid, topic_handler in bcfxml.topics.items():
-        topic = topic_handler.topic
-        print("Topic guid is", topic.guid)
-        print("Topic title is", topic.title)
-
-        # Fetch extra data about a topic
-        header = topic_handler.header
-        comments = topic_handler.comments
-        viewpoints = topic_handler.viewpoints
-
-        for comment in comments:
-            print(comment.guid)
-            print(comment.comment)
-            print(comment.author)
-
-    # Get a particular topic
-    topic = bcfxml.get_topic(guid)
-
-    # Modify a topic
-    topic.title = "New title"
-
-    bcfxml.save()
-```
-
-## bcfapi
-
-The `bcfapi` module lets you interact with the BCF-API standard.
-
-```python
-from bcf.v3.bcfapi import FoundationClient, BcfClient
-
-foundation_client = FoundationClient("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET", "OPENCDE_BASEURL")
-auth_methods = foundation_client.get_auth_methods()
-
-# Our library currently only implements the authorization_code flow
-if "authorization_code" in auth_methods:
-    foundation_client.login()
-
-bcf_client = BcfClient(foundation_client)
-
-versions = foundation_client.get_versions()
-for version in versions:
-if "3.0" in versions:
-    if version["api_id"] == "bcf" and version["version_id"] == "3.0":
-        bcf_client.set_version(version)
-
-data = bcf_client.get_projects()
-print(data)
-project_id = data[0]["project_id"]
-print(project_id)
-data = bcf_client.get_project(project_id)
