Revit Tag All Not Working? How to Fix Tag All Not Tagged
Revit Tag All Not Tagged doing nothing, skipping elements, or showing blank tags? Check tag families, visibility, linked models, and tag parameters.
On this page
When Tag All Not Tagged in Autodesk Revit does nothing, skips elements, or places tags that show ?, the problem sits in the tag family, the view settings, the linked model, or the parameter in the label. Each symptom points to a different fix.
Start with the basic Tag All settings below, then jump to the section that matches what you see on your sheet.
| What you see | What to check first |
|---|---|
| Nothing gets tagged | Loaded tag families, selected categories, existing hidden tags |
| Only some elements get tagged | View visibility, crop and view range, filters, separate element categories |
| Linked-model elements are skipped | Include linked files, Underlay setting, view discipline |
Tags appear as ? or blank | Element parameter values and tag-family label settings |
1. Check the basic Tag All settings first
- Open the Revit view you want to annotate.
- Go to Annotate, Tag panel, Tag All to open Tag All Not Tagged.
- Choose All objects in current view. If you had elements selected before opening the dialog, check that Revit did not default to Only selected objects in current view.
- Select the tag categories you need, such as Duct Tags, Duct Fitting Tags, or Pipe Tags. Each one is a separate category.
- Check that a tag family and type are loaded for each category. You can verify this under Annotate, Tag panel, Loaded Tags and Symbols.
- Click OK and check the view.
If nothing changes, test Tag by Category on one of the affected elements:
- Tag by Category also fails. Go to the family, category, visibility, and label checks below.
- Tag by Category works, and Tag All does not. Check whether that element already has a tag, whether it sits in a linked model set to Underlay, or whether the Tag All scope and view settings exclude it.
Autodesk's Tag All Not Tagged instructions confirm that the command tags untagged elements in the active view, not across the project.
Why running Tag All again will not add a second tag
Tag All Not Tagged lets you pick one tag family and type per category, and it skips any element that already has a tag in the view. If a duct already has a size tag, running Tag All a second time with an elevation tag type will not add the elevation tag. Autodesk's forum thread on using Tag All twice covers this same limit.
2. Tag All runs, and no tags appear
Check whether a tag already exists with a hidden label
Tag All Not Tagged skips any element that Revit already considers tagged, even when the existing tag's label is invisible.
- Find the tag family and type assigned to the category.
- Open the family in the Family Editor.
- Select the label and check its Visible property and any visibility parameter tied to it.
- Turn the label on and reload the family into the project.
- Check the view to see whether the existing tags appear.
Autodesk documents this case in Elements are not tagged when using Tag All.
Check the loaded tag family and category
A duct tag covers ducts only. Duct fittings, duct accessories, and flex ducts each have their own tag category. Pipes, pipe fittings, and pipe accessories are separate categories too.
Open Loaded Tags and Symbols, load any missing tag family, and select the matching category row in Tag All Not Tagged.
Check view visibility
Press VG (or VV) and check both Model Categories and Annotation Categories. Check whether a view template or a view filter overrides the visibility.
If a view template locks those settings, test in a duplicate working view without the template before changing a shared production template.
3. Tag All skips only some elements
When only part of the view gets tagged, compare the skipped elements against the ones that worked:
- View range, crop region, or scope box. Check that the missing elements sit inside the active view's visible range and crop.
- Filters and view template. Check whether a filter hides the model category, the tag category, or specific elements.
- Worksets. Check whether the workset holding those elements or their tags is hidden or closed.
- Phase, level, or discipline. Check that the view shows the phase and discipline those elements belong to.
- Existing tags. Check whether Revit already sees a tag on the element, including a tag with a hidden label.
- Separate MEP categories. Check whether you selected Duct Tags and left out Duct Fitting Tags or Flex Duct Tags, or selected Pipe Tags and left out Pipe Fitting Tags and Pipe Accessory Tags.
A quick test is to duplicate the view, turn on the categories without a view template, and run Tag All there. If the tags appear, compare the view range, filters, and template settings between the two views.
4. Tag All is not tagging elements in a linked Revit model
Linked models add a few extra gates. A linked piece of mechanical equipment or a linked pipe can accept Tag by Category and still get skipped by Tag All Not Tagged.
- In Tag All Not Tagged, tick Include elements from linked files.
- Open Visibility/Graphics (VG), go to Revit Links, and find the linked model.
- If Underlay is ticked, turn it off, run Tag All again, and restore your display settings afterward.
- Check the view's Discipline. If the linked category does not display as normal MEP geometry, test with Coordination and switch back after tagging.
- If elements are still skipped, turn off Crop View temporarily to test, then turn it back on.
- For linked rooms or spaces, check the linked model's level and phase mapping.
Autodesk notes that Tag All skips Underlay elements by design, even when Tag by Category works on them. If you want the link to print lighter while staying taggable, use Halftone instead of Underlay. See Tag All does not work with a linked model set to Underlay, and our full guide on tagging linked models in Revit.
5. Tags are placed, and show ? or blank text
When a tag shows ?, the command placed the tag and the label could not read a value.
- Select the element and check that the parameter used by the label has a value.
- Open the tag family in the Family Editor and check which parameter the label reads.
- Check whether that parameter is a type parameter or an instance parameter, and confirm the family reads the right one.
- Check that the tag family matches the element shape. A tag built for rectangular ducts will show
?on a round duct if its label only reads rectangular width and height. - If the tag is blank, check the label's visibility settings and the view's annotation crop.

6. Tag All works, and you have dozens of views to tag
Tag All Not Tagged runs in the active view only. It does not batch-tag floor plans, sections, and enlarged views across a drawing package.
In native Revit, you open each view and run the command again, or copy tags and use Paste Aligned to Selected Views where the views show the same elements. View templates control visibility and graphics, and they do not place tags. See how to use Tag All across multiple views.

What building a tagging cleanup workflow yourself really costs
- Time. Whoever builds and maintains the script is doing software development instead of the billable engineering and drafting work they were hired for.
- The AI loop.With Claude or ChatGPT it becomes an endless loop of “fix this”, “now fix that”. Each fix can break a case that worked before, and nobody on the team owns the code.
- Cost. Hours spent building and maintaining scripts, times your hourly rate, against $200 per month for RayCAD for the whole company.

Frequently asked questions
Why does Revit Tag All Not Tagged do nothing?
Check that the tag family is loaded, the category and scope are selected, and the elements are visible in the active view. The elements may also already have tags whose labels are hidden.
Why does Tag by Category work, but Tag All does not?
For linked elements, check whether the link is set to Underlay. Autodesk documents that Tag All skips Underlay elements while Tag by Category still works. Also check whether Tag All treats the element as already tagged.
Why is Revit Tag All not tagging linked elements?
Tick Include elements from linked files, turn off the link's Underlay setting in Visibility/Graphics, and check the view discipline, visibility, and crop settings.
Why do my Revit tags show a question mark?
The tag was placed, and its label cannot read the expected value. Check the parameter values on the element and the label setup in the tag family.
Can Tag All Not Tagged tag multiple views at once?
No. The native Tag All command runs on the current view only. Repeat the command in each view, or copy and paste aligned tags where the views show the same elements.
