### Intent

This scenario has a TIN with coordinates for `IfcTriangulatedIrregularNetwork` in map units (map metres)
This scenario has a TIN with coordinates for `IfcTriangulatedIrregularNetwork` in map metres
but using a local origin of (256400.0, 7011600.0, 0.0) to truncate the coordinates.
IfcMapConversion is used to translate data to the correct (Easting, Northing, Height) for the map projection.
The data is already in map units (map metres) so Scale is 1.
The data is already in map metres so Scale, ScaleY and ScaleZ are 1.
The Horizontal and Vertical datums are specified in `IfcProjectedCRS`.

The TIN has one colour for all the triangles and there are no voids in the TIN.

Special note: the data is *NOT* in local engineering coordinates.
The units for *x* and *y* are map units (map metres) and not ground units.
The units for *x* and *y* are map metres and not ground metres.
