public class cmdGetBuiltInParam : IExternalCommand

{

public Result Execute(ExternalCommandData cmdData, ref string msg, ElementSet elements)

{

UIDocument uiDoc = cmdData.Application.ActiveUIDocument;

Document doc = uiDoc.Document;

Selection sel = uiDoc.Selection;

Duct duct = doc.GetElement(sel.PickObject(ObjectType.Element, "选择")) as Duct;

foreach (Parameter p in duct.Parameters)

{

if (p.Definition.Name == "高度")

{

BuiltInParameter biParam = (BuiltInParameter)p.Id.IntegerValue;

TaskDialog.Show("builtIn", biParam.ToString());

}

}

return Result.Succeeded;

}
