Revit Time saving Tip #6 – Creating & Tagging Rooms in Linked Revit files

The tools

You can create tags in your host file to show the locations on Rooms in a linked file. You can also use a linked file to create new rooms in your host file should you need to. Sometimes we get support calls when these operations don’t work as expected. There are a few tips to remember to make it work smoothly.

Creating Rooms in a linked file

This is a reasonably straight forward process:

When you initially link a file, Revit will not set it to be Room Bounding – in plain terms it will ignore the walls and other objects inside the linked file and will not add Rooms inside those elements. This is very easy to fix:

1. Select the linked file.

2. In the properties window, click on the Edit type button.

3. Tick the box labelled “Room Bounding”.

4. Make Rooms as normal.


Tagging Rooms that exist in a linked file

This functionality was added a few versions ago due to requests from Revit users. If your other team members or another consultant has created Rooms in the linked file, you can simply tag them in your Host project without having to re-create them.

The biggest reason why this will not work is due to phase mapping. Phasing is used in projects to define different stages of the project (existing conditions, demolition, new works and so forth). Quite often practices will have their own phases built into their template that they will use in projects. There may also be an agreed phasing typology in larger collaborative project that define what phases have to be included in the Revit files produced by each party. If you do not have your phases in your project mapped to the ones in the linked file then when you go to create a Room in your project, it will not pick up the elements in the linked file as it regards the walls and other elements as from another phase so ignores them when you create the Room Tag.

1. Click on the linked file. Click on the Edit Type button in the properties window. Make sure that the phases in the linked file correspond to the ones in your host file. Consult with your BIM Execution Plan if one has been agreed to for the project


2. Once done, you can now create tags. In some instances Revit will not allow you to use the “tag all not tagged” so you may have to tag each Room manually. Once you’ve done this though, remember you can select one of the Tags, use the CS (select all) shortcut, then type CTRL-C, then go into the View you wish to place the tags into and type CTRL-V. Just make sure you are in a view that is on the same level in the model otherwise the operation will not work.

NOTES: Make sure that you turn Room Tags on in visibility settings prior to doing this otherwise you won’t see your output. It may also be helpful to turn “room references” on in order to see the diagonal cross that denotes the location of the Rooms.

Have fun!
