Revit 2018 has given mechanical engineers added capability in defining Building Types and Space Types within Revit project files. Building and Space Types are used for energy calculations and it is always a good thing when Autodesk provides more opportunity to improve the energy analysis and design process.
Building and Space Types are defined in the Building/Space Type Settings dialog box accessed by the Manage tab -> MEP Settings on the Settings panel -> Building/Space Type Settings.
Revit 2018 finally fixes an awkward dialog box. The ability to quickly add tags to a Revit view through the “Tag All Not Tagged” command has been around a long time, but the dialog box for it has always been a bit klutzy. In Revit 2018, you can now place a checkmark next to the desired categories to be tagged. This makes it work like other dialog boxes and I think more user friendly. While this isn’t a huge new feature with increased productivity or capability, I really like it.
