Dimension walls in plan to core or with finishes turned off

[KeesW]

I've just discovered something that others might want to check. I am dimensioning to the core because this is required for my documentation.
I have a composite wall comprising 90 mm stud with 10 mm plasterboard both sides. I noticed 10 mm errors in some of the dimensions. Turns out that Archicad may measure to the wall's reference line if this is on the outside or inside of the wall surface. Adjusting this by 10 mm to bring it to the face of the stud fixes this. I thought that the dimensions would measure to the core if that is what I selected, regardless of the position of the reference line.
