How to avoid collecting "Model in place" element

[amir.aroesti]

hi

I have some model in place element that I want to avoid collecting them in my element filter collector.

            FilteredElementCollector collector = new FilteredElementCollector(doc);
            ElementCategoryFilter filter = new ElementCategoryFilter(BuiltInCategory.OST_Walls);
            IList<Wall> walls = collector.WherePasses(filter).WhereElementIsNotElementType().Cast<Wall>().ToList();

[amir.aroesti · Accepted solution]

FilteredElementCollector BasicWallCollector = new FilteredElementCollector(doc).OfClass(typeof(Wall));
IEnumerable<Wall> walls = BasicWallCollector.Cast<Wall>().Where(w => w.WallType.Kind == WallKind.Basic);
