12 17, 2015 – Autodesk releases a new version of Storm and Sanitary Analysis 2016 for IDS 2016 customers.
If you have the Infrastructure Design Suite, this new version of Storm and Sanitary Analysis 2016 seems to require and uninstall and reinstall for the 32-bit and 64-bit plugin for AutoCAD Map 3D.
The current version of the Autodesk Application Manager does not appear to recognize the install process, but the install functions and so does Storm and Sanitary Analysis 2016.
No substantive details of the changes made were included in the attached Autodesk Readme.
