Filtering of structural columns...!?

I have a preference for Predicate and PLINQ extension, but it is not necessarily the fastest methods

there are some tests here

Python to get specific family?

Hello for information, it is not because a code is shorter that it will be more efficient some examples to compare execution times with SlowFilter (Revit API) [image] with List Comprehension [image] with Predicate [image] with LINQ [image] with filter [image]
