Which Subscription download contains the Floor Vibration Analysis addon for Revit Structure 2012? I've found the one for 2011, but no 2012.
If you have subscription you can download Revit Structural Extension for 2012.
After downloaded, Floor Vibration Analysis should appear under Extensions> Analysis (see attachment)
Hope that helps.
The name is exactly like in the pdf file I sent you: Revit Extensions for Autodesk Revit Structure 2012.
The Floor Vibration is listed in the pdf document under the Appendix.
So I was right, I do have the correct extension installed on my PC, but the panel for the extension doesn't show doesn't show. See that attached image. Why might that be?
