Selection Filter

When you are selecting elements in your Revit file it is can be difficult to select all of the elements you require. An easy way to refine your selection is to use the Filter (not to be confused with a view filter).

This will allow you to highlight multiple elements and then refine the selection by using the filter to identify the categories you would like to have selected.

In the example below I just want to select the doors, so I am selecting the entire model first and then filtering my selection to just have the doors selected.
