For users of the Building Design Suite Premium 2013 on Subscription, you will have access to 3 versions back of the products in the Suite.
One of the new product additions to the Building Design Suite Premium 2013 is access to Navisworks Simulate 2013.
NOTE: The Building Design Suite Premium 2012 did NOT contain Navisworks Simulate 2012, therefore, you will not be able to run Navisworks 2012 Simulate with a Building Design Suite Premium 2013 on Subscription license.
These Technical Solutions mention previous versioning support here:
Understanding Previous Version support for Autodesk Suite products
Understanding Previous Version support for Autodesk Point products
Previous Version support allows Suite licenses to only consume a single license for every application from the same release year of the Suite. If the Autodesk Suite product did not exist in the previous year then each previous version of a product that is launched will consume a separate license. Since no Autodesk Suites exist prior to the 2011 release year, launching a previous version of all 2010 and 2009 products will always consume one license each.
For example, if you have a package license for Autodesk Design Suite Premium 2012, the following scenarios can be expected:
- Running AutoCAD 2012, 3ds Max Design 2012, and Mudbox 2012, on the same workstation and at the same time, only consumes one license.
- Running Showcase 2011 and Mudbox 2011, on the same workstation and at the same time, also only consumes one license because there is a 2011 version of Autodesk Design Suite Premium.
- Running AutoCAD 2010 and 3ds Max Design 2010, on the same workstation at the same time, consumes two licenses (one for each product) because there was no version of Autodesk Design Suite Premium 2010.
