BIM: ArchSpace - Inconsistent computed Vertical Area

[marcuspollio]

Is there an existing issue for this?

• I have searched the existing issues

Problem description

In the BIM Workbench, the ArchSpace provides several computed values from its geometry, such as the horizontal area, the perimeter length (both now, with 2 methods), and also the Vertical Area.
However, this third computed value is not always correct. For vertical extrusions (prismatic spaces based on a flat XY profile), there are no issues. But when ArchSpaces have inclined faces or curved features, the Vertical Area provided can be wrong or misleading.

In the example below, the first Space ("Trapezoid") has two inclined faces which are not computed in the Vertical Area. These two inclined faces are not really vertical indeed, so one could say it's correct.
The third and fourth Spaces ("Barrel_Vault" and "Sphere") have curved features, which are not vertical either.
Yet they are included in the calculation of the Vertical Area.

For consistency sake, one would expect that either all strictly vertical-only areas are computed, or all non-horizontal areas are computed. The latter would cover a wider range of situations. This is open to debate, of course =D

Hi,
I can try to correct this as well. :) In my opinion vertical areas should only count vertical areas, otherwise we should call it non horizontal areas? Any other ideas?
