Extensions are a series of additional functionality or content which can be added directly into a deployment image.
Extensions can be included by selecting the desired items. Items which contain a description can also be found in the Product Updates section of Autodesk Account.
Note: Only Autodesk published extensions can be included within a deployment image. Non-Autodesk published additional software is no longer supported directly within a deployment image. Additional software can be deployed using industry standard deployment mechanisms such as SCCM or Microsoft Configuration Manager.
