The Revit team regularly publishes the roadmap for Revit which details in a very transparent form what they are working on so that you can expect and prepare for including the request for 2D PDF printing and better collaboration between structural and analytical models on the roadmap.
“HOW DO I GET INVOLVED?
There are a variety of other discussions and work related to connecting workflows from design to fabrication and beyond. If you don’t see something listed here, it doesn’t mean that it isn’t on our radar. If you have specific suggestions for ways we can make the product better, we encourage you to submit them to Revit Ideas.”
