"""Create a blank IFC model file object
|
|
|
|
Create a new IFC file object based on the nominated schema version. The
|
|
schema version you choose determines what type of IFC data you can store
|
|
in this model. The file is blank and contains no entities.
|
|
|
|
It also sets up header data for STEP file serialisation, such as the
|
|
current timestamp, IfcOpenShell as the preprocessor, and defaults to a
|
|
DesignTransferView MVD.
|
|
|
|
:param version: The schema version of the IFC file. Choose from
|
|
"IFC2X3", "IFC4", or "IFC4X3". If you have loaded in a custom
|
|
schema, you may specify that schema identifier here too.
|
|
:return: The created IFC file object.

# Start a new model.

# It's currently a blank model, so typically the first thing we do
