hide selected elements

[sabatierae]

Hi,

I try to create a program that hide selected element.

I wanted to do something like that

Selection sel = uiApp.ActiveUIDocument.Selection;


// How Can I get the elementsId of my selection?
// This "list" is called elementIdCollector


ICollection<ElementId> collectionSelectedElement = null;

foreach (ElementId eId in elementIdCOllector)
{
collectionSelectedElement.Add(eId)
}

doc.ActiveView.HideElements(collectionSelectedElement);

Can someone help me please?

Thank!!

For revit 2015 you can simply do:

List<ElementId> selectedIds = uiApp.ActiveUIDocument.Selection.GetElementIds().ToList();
uiApp.ActiveUIDocument.ActiveGraphicalView.HideElements(selectedIds);
