Renzo van Rijswijk just pointed out that he offers some free Revit add-ins on his blog RevitToday:
- Import coordinates into Revit 2011 for importing coordinates from a TXT file. You are free to select a family of your own. It should be a Point Based family of course.
- Export XYZ from Revit 2011 to export all coordinates of Point Based Generic Models to an Excel file. You can locate Point Based Generic Models in your whole model. You are able to nest such a Family within another. These points are exported as well when you make this family Shared.
