Returns a handle to the model within the Geometry Kernel.
Note: the STEP Engine uses one or more models within the Geometry Kernel to generate design trees
within the Geometry Kernel. All Geometry Kernel calls can be called with the STEP model handle also,
however most correct would be to get and use the Geometry Kernel handle.
By default a model for the Geometry Modelling Kernel will be created once required on-the-fly.
This call allows a user to use an existing model that will be connected. This connected model
will not be destroyed at closing of the STEP model, i.e. within sdaiCloseModel().
Returns a handle to the instance representing the head of design tree within the Geometry Kernel.

The call getGlobalPlacement is meant to be used together with setGlobalPlacement(..) and allows you to get and adjust the placement of a model.
This is all done semantically, i.e. it can be seen as a derived call representing a small SDAI function adjust (in case of set) the
origin of a model.
The call setGlobalPlacement allows you to adjust the placement of a model.
This is all done semantically, i.e. it can be seen as a derived call representing a small SDAI function adjust the origin of a model.
This call allows certain constructs to complete implicitly already available data.
Specifically for IFC4.3 and higher calls using the instances of the following entities are supported:
IfcAlignment => in case business logic is defined and not geometrically representation is available yet
the geometrical representation will be constructed on the fly, i.e.
an IfcCompositeCurve with IfcCurveSegment instances for the horizontal alignment
an IfcGradientCurve with IfcCurveSegment instances for the vertical alignment
an IfcSegmentedReferenceCurve with IfcCurveSegment instances for the cant alignment
IfcLinearPlacement => in case CartesianPosition is empty the internally calculated matrix will be
represented as an IfcAxis2Placement
