Revit Room Tag

How to create room tag including width x depth parameters and a nice use of maths room length.
Revit room tag. Revit displays a warning if the room is not in a properly enclosed region. To tag a room open a plan or section. This tool can be useful for example when you place and tag rooms in a floor plan view and you want to see tags for the same rooms in a reflected ceiling plan rcp view. As described in the article how to define room bounding elements in revit many element types are room bounding by default such as walls floors ceilings etc.
When you create a room if it is properly bounded by elements such as walls and room separation lines revit computes the room area between the boundaries. Fortunately whenever you copy an element in revit it will always take on the phase of the active view regardless of what it was set to before. If you do not use the tag on placement option when creating rooms you can tag rooms later. The key thing to understand here is that revit rooms exist only in one phase.
Room tags are annotation elements that can be added and displayed in plan views and section views. Room tags can display values for related parameters such as room number room name computed area and volume. To place a room tag when creating or placing a room in a view select the tag on placement option. Area room length example included.
Found this very useful. In revit you need to show room areas in different phases and are not sure how. So you need a whole new set of the applicable rooms for each phase. As an alternative use the tag all not tagged tool to tag all untagged rooms in a view.
To have the room areas ignore the columns the same exact solution described above can be applied to the columns simply select the columns and toggle off the room bounding parameter. Perimeter 2 sqrt perimeter 2 2 4 area 2 room width.
