From the Autodesk App Store:Description
Dynamo Multiplayer is a Free Autodesk® Revit® Add-In by Bird Tools. It is the ultimate universal Autodesk Revit batch processing tool, allowing the user to batch process several Revit models or families using one or multiple Dynamo scripts.
The range of functionalities offered by Dynamo Multiplayer is infinite, as the user can use it to batch export PDF, NWC, DWG, and IFC…files from Revit, to batch edit multiple Revit models, to achieve batch project setup, to batch perform quality assessment operations, to batch load families, to batch upgrade models, to batch edit families… and all of that using Dynamo, which provides the user with the highest level of flexibility. That makes Dynamo Multiplayer a universal batch processor for Revit.
Not only that, Dynamo Multiplayer takes Revit add-ins to a new unprecedented level, as it’s probably the first free non-Autodesk Revit add-in ever to support Autodesk® BIM 360®/ACC models through Autodesk Platform Services (APS, formerly Forge): the tool can batch process BIM Collaborate Pro (a.k.a BIM 360 Design) workshared models as well by retrieving them through APS, batch controlling them through the Revit API, and processing them using Dynamo.
Moreover, starting with v1.1, users can schedule automated Dynamo runs, so that multiple models can be automatically processed at a user-specified time, which can also be regular daily or weekly scheduled Dynamo runs.
