Describe the bug

When converting walls with hosted elements, e.g. windows and doors, the area of these openings is relevant for different use cases. However, no parameter converted represents the area of the hosted element within the host. While we expected that the parameter HOST_AREA_COMPUTED would correspond to this desired value, we found out that this is not always the case (see https://thebuildingcoder.typepad.com/blog/2015/03/ifcexportutils-methods-determine-door-and-window-area.html).

To Reproduce

Export from Revit to Speckle.

Expected behavior

We would expect a parameter representing the area of the hosted object within the host as illustrated in the following image.
