Export Revit elements by parameter value

I was asked if it was possible to export elements from Revit based on a parameter value. I right away thought of perhaps using filters for this.

To get this to work I did the following:
Create a project parameter (shared)
I was a bit lazy here by assigning it to all categories
  • Create a filter
  • Do not check all categories here because everything will limit your parameter chooses
  • Filter by: Export --> equals --> No
  • OK


  • Add the filter to a 3D view
  • Uncheck the visibity
By unchecking the visibility every element that has the values NO gets turned of. When you export the view you set the settings to only export the visible parameters
Two extra things the Yes/No parameter I have use here has this greyed out state by default.
 An easy way to fix this can be done by schedule.
 Below you see an image of the view with the filter in action

A nice addition to this might be using the extension RTV tools of Jason Howden http://www.rtvtools.com/
