I have just downloaded and tested the Excitech Revit Toolkit. The toolkit features 2 'main' add-ins for Revit. The first is a coordinate scheduling tool which is very useful for any project where you have a coordinates system and need precise locations of objects or elements - You add the category of elements through the add-ins tab and coordinate parameters are added to the instance properties of the selected elements. You can then view and export your coordinates schedule directly from Revit.
