Why Wall Miter Join exists
Wall joins are the small ugly thing at the end of every drawing set. Two walls meet at a corner, Revit picks a butt join, and the plan shows a seam where the finish should carry through. Fixing one is easy - right-click the join, cycle it, done. Fixing dozens of intersections across a floor plate is an afternoon of clicking, and it comes back every time someone adds a partition.
How Wall Miter Join works
Open the view you want cleaned up and click Wall Joins. It works on the walls visible in that view, so the view is your scope - no preselection needed.
A confirmation dialog tells you how many walls it found and exactly what it is about to do, before anything changes.
Both ends of every wall are set to a mitred join.
Wall endpoints that actually touch - within 50 mm of each other, and at least 5° apart in angle - get their geometry joined. The opposite ends are locked so the join does not propagate down the wall.
You get a summary: new joins created, pairs already joined, parallel walls skipped, non-touching walls skipped.
Before
Corners get cleaned up manually, usually late, usually by whoever is checking the sheets the night before issue.
After
The join pass is one command you run per view before you start checking, so what you are reviewing is the drawing rather than the joins.
When to reach for it
- Cleaning up a model you inherited, where join behaviour was never set consistently.
- Right before a plan issue, as part of a pre-issue sweep.
- After a partition layout change has added a lot of new wall ends.
What it does not do
- Parallel walls are skipped on purpose. Joining them tends to produce dimension and join-stability warnings, so the tool leaves them alone and tells you how many it passed over.
- Walls whose ends are more than 50 mm apart are not joined. If your model has gaps wider than that, close them first.
- Scope is the active view. Walls hidden by the crop, a filter or a view template are not touched - which is useful, but means the whole model is not done in one click.
- It sets joins to Miter. If your standard calls for butt joins in specific conditions, those need setting back by hand.
- Join warnings raised by the run are cleared as it goes. That is deliberate - a clean pass across a floor plate would otherwise leave you a dialog per intersection. Errors are not touched.
- On a workshared model, walls owned by someone else are dropped before the run starts and the endpoint matching is redone on what is left. If every wall in the view is locked, the summary comes back as zeros - a worksharing result rather than a bug.
Questions
- Will this change my wall structure or layers?
- No. It changes how walls join at their ends and joins touching geometry. Wall types, structural layers and materials are untouched.
- Can I undo it if the result is wrong?
- Yes. The whole run is a single Revit transaction, so one Ctrl+Z reverses it. The confirmation dialog reminds you of this before it starts.
- Does it clean up the whole model or just what I can see?
- Just what is visible in the active view. To cover a whole building you run it per plan, which also means you can deliberately exclude areas by cropping or filtering the view.
- Why were so many walls skipped?
- Two reasons, and the summary separates them: walls running parallel to each other, and walls whose ends do not come within 50 mm. Both are deliberate - joining either kind causes more problems than it solves.
