Working with Spaces in a Linked Model

You can place spaces in a project that is located on your computer or in a linked model.

If you have not worked with a linked model, you should review the linked model information.

Working with spaces in a linked model is a common practice for MEP engineers, however, you should review the important facts below.

Important facts about spaces in a linked model

• If a linked model containing rooms was created in a previous version of Revit and opened in Revit 2022, spaces may be automatically created during Project Upgrade. These spaces are based on the existing rooms. Rooms will remain in the project but you can deactivate their visibility in the Visibility Graphics dialog.

  Certain conditions must be satisfied for automatic space creation to occur. See About Space Creation During Project Upgrade for more information.

  Note: Spaces are independent of rooms and can be defined according to your specification.
• If spaces are automatically created from existing rooms, always verify the vertical extents and boundaries of the spaces, and modify them if necessary.
• You must specify the linked model as room-bounding to be able to place spaces. This property is off by default.
• Always use the recommended space placement methods to place spaces in linked model.
• You cannot specify a room-bounding component as non room-bounding when working with a linked model.
• All spaces (and zones) in the MEP project must be in the host file.
  Note: Volume computations and heating and cooling loads analyses are not supported if the analyses are based on spaces (and zones) that reside in a linked model.
• The phase of the space must match or correspond (if it has a different phase name) to the phase of the room in the linked model.
