Have you ever created a room in an Autodesk Revit floor plan and tagged it to get the area and volume, but for the volume it shows as ‘Room Volume is Not Computed’? This is because volume computation may affect Revit performance, so we enable it only when we want to prepare and print schedules or other views that report volumes.
To see room volumes on the Properties palette, in tags, and in room schedules, we must enable volume computations.
Note: Volume computations may affect Revit performance.
You can turn on volume computation to prepare and print schedules or other views that report volumes. Then turn off the feature.
Click Architecture tab> Room & Area panel drop-down > (Area and Volume Computations).
On the Computations tab of the Area and Volume Computations dialog, under Volume Computations, select (to enable) or clear (to disable) Areas and Volumes.
Revit computes room volumes by determining the room area, then determining the room height. It then uses the room area and the room height to compute the room volume.
You can get loads of great additional functions with Graitec PowerPack for Revit.
