No integral project agreements
Translation: “Unreliable Ice, Acces prohibited”
Unreliable model information
“Models for information purposes only”
“Details not generated from the model”
“I'm not sure the information in te
model is correct”
“Use at your own risk”
“Paper drawings are leading”
Information is not complete
No value where the material should be filled in Unknown entity
Different values about the structural class in one object
