Well, the latest service pack for Revit is now available! You can download the update HERE. As always, make sure you download the appropriate version (for OS) and read the Readme file.
The update list isn’t available yet, but check back on the download site within the next couple days and it should be available.
I posted this morning that SP2 was needed in order to utilize the Cloud Rendering that’s now available via the Autodesk Cloud. So once you install SP2, you should now be able to utilize the Add-in for Cloud Rendering.
