Filter elements where clause

[Anonymous]

Hi,

I don;t know what am I doing wrong but I am trying to get a FilteredElementCollector with multiple where clause but its not working:

                        Element Ele = new FilteredElementCollector(Command.doc, Command.doc.ActiveView.Id).WhereElementIsElementType().ToElements().Where(o => o.LookupParameter("Diameter").AsString() == "150 mm" && o.LookupParameter("TEXT").AsString() == "NORTH BOUND TRACK LEVEL").First();

Thanks & Regards

Hi

First you mentioned All Element and not Element Type: so you need to change "WhereElementIsElementType()" to "WhereElementsISnotElementType"

Second: you mention all Element in the Document and not View Specific:  you need to omit "Command.doc.ActiveView.Id"

Third double check : Spelling mistake and Case Sensitive.

Last: If Diameter is a builtin Parameter, then you need to look into the the right builtinDefinition as it is more safe to find the exact value.

Hope this helps
