I wished Revit MEP allows to rotate sloped pipe with fitting base on center line of pipe. It is very difficult to rotate sloped plumbing piping to connect other pipe & fitting in rolling offset configuration. Please refer to attached print screen for details.
This is also being a large problem for our facility since we have many large drain systems leading away from our production tools that are all sloped (every building has waste drains). I am wondering why AutoDesk missed the basic assumption of centerline based functions that are the core of routing pipe (I also find no snap/work points on the corners of any of the fittings) . This was an easy process in Intergraph's PDS system 25 years ago. Maybe they should get an old copy of that software and learn to "talk pipe designer". I've also found the 6 ordinate directions no where to be found in the routing tools. These too would be a very welcome addition to the core tools that get the model built.
Just my opinion.
