Here is a little note I wrote sitting in Washington Dulles airport and did not get around to posting until now, to point out the importance of using language independent category comparisons:
Question: Apparently at least one category name changed in the German version of Revit from 2009 to 2010:
- Revit 2009: "Tragende Stützen"
- Revit 2010: "Tragwerksstützen"
We rely on category names for mapping purposes. In this case we discovered the change that was causing problems for us, but I am worried that there may be other similar changes that I also need to be aware of. Is there any way to use a language independent identifier that will never change? I very much hope to find a way to identify categories in a language independent fashion.
Answer: You can use the built-in category enumeration to make your code language independent when working with categories. We looked at this and related topics in the discussions on category comparison and later explored it further for the model element selection, which we recently enhanced to handle a set of multiple categories using a list of built-in category enumeration values stored in _bics_to_skip and the helper method SkipThisBic to compare them all with a given value from a candidate element.
