You need every interior wall on this plan selected so you can change one parameter. There are fourteen wall types on the level, and the plan is full of doors, furniture and tags you don't want in the selection.
Revit gives you two ways to do it. Both work, and both have a limit you hit quickly.
Select All Instances
- Select one wall.
- Right-click and choose Select All Instances.
- Pick Visible in View or In Entire Project.
Revit selects every element of that same type, and that's the catch. It works by type, so a plan with fourteen wall types means finding one wall of each.
Visible in View only picks up what the view is showing. That's usually what you want, but remember it when something is hidden or cropped out.
A window selection and the Filter tool
- Drag a box around the area. Left to right takes only what's fully inside it. Right to left takes anything the box touches.
- Click Filter, the funnel icon on the ribbon or at the right-hand end of the status bar.
- Click Check None, tick Walls, then OK.
Now you have every wall, whatever its type. The limit here is that Filter only sorts by category. It can tell a wall from a door. It can't tell an interior wall from an exterior one.
Why interior versus exterior is awkward
Interior and exterior are values of Function, a type parameter on wall types and door types. The Filter dialog only reads categories, so it never sees that parameter.
So in plain Revit you end up going type by type with Select All Instances, checking each type's Function as you go. Or you take everything and Shift-click away the walls you didn't want.
On a small job that's fine. On a hospital floor with thirty partition types it's fiddly, and one missed type means one set of walls that never got the change.

One button per selection
NexionTools adds a Select panel to its tab in the Revit ribbon. Seven of the selection tools on it are free:
- All Walls selects every wall visible in the active view, whatever the type.
- Int Walls selects the walls in the view whose type Function is Interior.
- All Doors selects every door visible in the view.
- Ext Doors selects the doors in the view whose type Function is Exterior.
- Roofs selects every roof visible in the view.
- Ceilings selects the ceilings on the view's level. It searches the whole project, so it can pick up a ceiling the view is hiding.
- Beams selects the beams in the view that sit on the view's level, leaving out braces, trusses and joists.
Each button replaces whatever you had selected, and then you carry on in Revit as usual. For the first five the view is the scope, so crop the view and the selection follows. Ceilings and Beams need a view with a level, so they do nothing in a 3D view.
The interior and exterior buttons read the same Function parameter described above. If nobody kept it up to date on your types, you get what the data says.
The other buttons on that panel, for exterior walls, interior doors, floors, windows and rooms, belong to the paid suite. The pricing page covers those and the 7-day trial.
Check the Function data before you trust it
Highlight Exterior Walls is free as well. Click it and every wall in the active view whose type is set to Exterior gets a solid blue fill.
It's a quick way to spot the facade wall somebody built with an interior type. Click the button again and each wall goes back to how it looked before, including any overrides it already had. No view filter is left behind.
Turn it off with the button rather than Ctrl+Z, and do it before you close Revit. The record of each wall's original appearance only lasts for the session.
Put the seven selection buttons on your ribbon. They are free forever with no credit card, alongside five other free tools. Download NexionTools free
