If you have a complex profile with different depts, you dont get the accurate panel surface m2 in BIM collab/solibri. Archicad just measures the project area (green line perimeter X element height instead of the red line perimeter X element height).
What i end up doing is custom properties
measure the height of the element is multiplied by the perimeter of the outside surface ( red line in drawing above, that i have to measure this myself).
different property. for every panel
have to change the formulas if the panel changes
Cant we have an option to draw a line as a modifier that can then be used in custom properties.
1 property for all the different complex profiles
100% accurate m2
If this is too complex then at least be able to extract the "component area base line " as a property.
