All elements in a active view

[Anonymous]

Hi!

How can I get all the elements of all categories available in a active view? Must I use a filteredCollectorElement?

Yes.

It is the best way to collect the elements from any document. You can directly pass the ActiveView.Id to the FilteredElementCollector overload to collect only elements visible in that view.

var col = new FilteredElementCollector(doc, doc.ActiveView.Id).   
   Cast<Element>().
   ToList();

For anyone reading this in future sometimes you might want to add a filter (I know that I did).

For example, here is a snippet i ripped out from an addin i was developing.

FilteredElementCollector filter = new FilteredElementCollector(doc, doc.ActiveView.Id);

var filteredDimensions = filter.WherePasses(new ElementClassFilter(typeof(Dimension)))  
      .ToElements()
      .Cast<Dimension>()
      .Where(d => dimensionIsGood(d))

// we can filter IN dimensions
// and filter out via any condition we want
