The state of the IFC import code base in ada is currently outdated and unstable. This is primarily due to the current implementation (or lack there of) of unit conversion.

Investigate the unit conversion handling in IfcPatch [here] (https://github.com/IfcOpenShell/IfcOpenShell/blob/v0.6.0/src/ifcpatch/ifcpatch/recipes/ConvertLengthUnit.py)

Todo:

• Rewrite code
• Add Unittest - Read IFC file with native beams
• Add Unittest - Read IFC file with native plates
• Add Unittest - Read IFC file with native pipes
• Add Unittest - Read IFC file with native walls
