Description

Something is wrong with the export of the base quantities.
Double parameter names and incorrect units.

In the IFC file there are 6 walls with different geometry.
All 6 walls have the same value on the first NetSideArea in the list (display's length x height, which if even incorrect)
Definitions by Buildingsmart:

The second NetSideArea displays the correct NetSideArea.

Didn't check this issue for other IFC entities.

Used the 20.1.0.1 release.

Research direction

Reproduce the export with the six differently shaped walls using the 20.1.0.1 release and inspect the IFCWALLSTANDARDCASE base-quantity output. Compare the duplicated NetSideArea entries and their units with the BuildingSMART definitions; done means each wall has the correct NetSideArea values without duplicate parameter names or incorrect units.
