First I want to applaud the entire Enscape team, Developers and Support alike. You all are doing a phenomenal job answering questions and being active in the forms, as well as being incredibly fast with development requests. Great work!
So, that said, I wanted to know more about your RPC models. I've noticed you have a lot of Enscape models in the ...SystemData> Models folder. My assumption is these are your replacement files for the existing RPC content in Revit. Are these .EMF's RPC proprietary? Or are they property of the Enscape team? If its the latter, it would be awesome if you allowed their usage inside Sketchup and Rhino as Proxy objects! Having access to content is always important, especially if those models are optimized specifically for Enscape.
Thanks, Looking forward to your response!
