Search for free Revit plugins and it's hard to tell what you're getting. Free for good, or free until a trial runs out and the button you liked goes grey.
So here is exactly what's free in NexionTools. It's a set of 52 native add-in tools for Revit 2024 to 2027 on Windows. Twelve of them are free forever, with no credit card. This is what those twelve do, and where each one stops.
The four bigger tools
Warning Triage
Warning Triage scans every warning in the model, groups the identical ones and sorts the groups into High, Medium and Low. Pick a group and you see Revit's message, what it means in plain language and how to fix it, with the affected elements listed so you can select them or copy their IDs.
It changes nothing in the model. Fixing a warning is still your call.
Element X-Ray
Element X-Ray tells you why an element won't show in a view. Select the element, pick the view, and it runs 60 checks and lists the ones that failed. About ten causes come with a one-click fix, such as unhiding the element or turning a category back on.
It checks one element against one view at a time. If you'd like to understand the causes yourself, there's a guide to the manual checks.
Legend Placer
Legend Placer puts one legend on as many sheets as you tick, in the same position on each. You copy the position from a sheet where it's already right, or anchor it to a title block corner with an offset in millimetres.
A sheet where the legend would overlap an existing viewport is skipped and named in the result.
Load Family
Load Family checks families before they reach your project. Pick as many .rfa files as you like and each goes through eight quality checks, including file size, naming and CAD imports nested inside.
Every family comes back approved, approved with warnings or rejected. You untick the ones you don't want and load the rest in one go. A rejected verdict is advice, so you can still load that family. Each file is opened to be checked, which means a big batch takes a while.
All four install together and cost nothing. One installer adds a NexionTools tab to your Revit ribbon, and nobody asks for a card. Download NexionTools free
Eight one-click buttons
Highlight Exterior Walls gives every wall in the active view whose type Function is Exterior a blue fill. Click it again and the walls go back to how they looked. It leaves no view filters behind.
The other seven are selection tools. One click each, and the selection is ready for whatever you do next in Revit.
- All walls visible in the active view, whatever the type
- Interior walls, read from the wall type's Function parameter
- All doors visible in the active view
- Exterior doors, read from the door type's Function parameter
- Roofs visible in the active view
- Ceilings on the view's level
- Beams on the view's level, without braces, trusses or joists
The interior and exterior buttons trust the Function parameter. If it was never set properly on your types, the selection will be off in the same way.
What free means here
The twelve tools above are free forever. No card, and nothing to cancel.
The other 40 tools are paid. You can try all 52 for 7 days without a card, and the 7 days start the first time you open the tools in Revit. When the trial ends, the twelve free tools keep working.
Paid plans come with a 14-day money-back guarantee. The pricing page has the details.
NexionTools is a native Revit add-in, so it doesn't run through pyRevit or Dynamo. It's Windows only, like Revit itself.
If you'd rather compare other products before installing anything, the roundup of Revit plugins for 2026 is the place to start.
Start with the twelve that stay free. Install once, open Revit and run Warning Triage on your live model, with no credit card needed. Download NexionTools free
