Problem Description

The i-model plug-in for Revit 2016 is rumored to be released late in the second quarter of 2016

Steps to Resolve

1.  If you do not already have Structural Synchronizer and the ISM Revit Link plug-in installed you can download the installers here:

   https://store.bentley.com/en/products/iware/1000ISMRPI--ISM-Revit-plug-in
   The ISM Revit Link plug-in will add a Bentley tab to your Revit menu.
2. From the Bentley tab select Create ISM Repository and export the Revit model. If you need additional information on using the Revit plug-in, see these articles on Bentley Communities:
   ISM Revit Plug-in
3. Open the repository for the export location using ISM Viewer.
4.  On the menu select File > Publish i-model.

 One drawback to this method is that it only exports structural elements from the Revit model.
