Apply the filter to the elements

Anonymous — Tue, 23 Jul 2019 11:04:38 GMT

G'day all!
im trying to figure out how can i copy value E.g. from one parameter to another but only for one category in my active document (E.g. walls)

when i find all Wall instances in my document and i apply the filter to the elements (using ElementCategoryFilter and FilteredElementCollector), i dont know how can i easiest pick only Elements from my list, not ElementIDs

part of my code:

...
IList<Element> walls = collector.WherePasses(filter).WhereElementIsNotElementType().ToElements();

foreach (Element elem in walls)
{
Element e = doc.GetElement(elem); //in this line it gives me cannot convert type Element to ElementID

try
{
Parameter p = e.get_Parameter ...

p.Set (....

}
....

thanks

Hi @Anonymous

try using the below code

IList<Element> walls = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Walls).WhereElementIsNotElementType().ToElements() as IList<Element>;
                foreach(Element wall in walls)
                {
                    //Get element Directly
                    Element e = wall as Element;
                    Wall w = e as Wall;
                    /*
                     * Your code
                     */
                }
