@Hans_Lammerts
Thx for referencing that very good article that provides good insight!
I would like to cite some important parts out of this article:
“A final guideline that we propose from this project is to make formal agreements on how specific situations should be modeled with IFC. Even within the same file we encountered differences for similar situations.”
“… we have shown that a clear and specific modeling of IFC (with the associated validation tools) is required …”
“Making agreements for this, recording these in open standards and strictly following these standards is an important next step.”
This is similar to what I had in mind as I stated “I propose a modelling standard based on building-science and building-practice instead of software-vendors preference.”
