Is it possible to batch process Revit files using Rhino.Inside Revit?
depends on the process, no? Batch processing is complicated business in Revit, with the versioning and all.
You have access to open files, add and save families in the native RIR components. If you know python and the revit api you can do much more.
No using RIR at the moment. But pyRevit has a command line utility that can run python scripts over your Revit models. It automatically detects the model version and starts the appropriate Revit version. See Batch Processing Revit Models under pyRevit CLI guide
In my case, the closest thing I’ve been able to do was to programatically open, modify and then save some documents, given a list of paths, once RiR is already up and running… although I remember having a few issues at the time with the Python script. I haven’t been able to further test my scripts in a while, but will try to catch up in the winter.
