This issue had been debated all over the place- and what i have read has confused me further.
Issue: The rating of the wall is an type parameter- while i want it to be a instance parameter. Why? Because 2 walls built identically may not need to be considered rated- which allows penetrations etc. w/o firesafing.
Possible solution: While it would be silly to remove fire rating at the type parameter- a "use fire rating" switch could be added to instance parameters?!
So using filters is out for me (unless i add wall types)- and lines seem a bit inelegant a solution.
If any of you have worked around this- please advise!
