Auto Join Pro

Auto Join Pro

Joins, cuts and tidies how walls, floors, columns and beams meet across your whole model in one run. Instead of joining elements two at a time and hoping the cut goes the right way, you describe which categories should join in a few rules, preview exactly what will change, and apply it all in one click - and one undo.

How to use

1. Open Auto Join Pro from Revit with your project open - it reads the model's categories, families and types automatically.
2. Under Run setup, pick the scope: the entire model, the active view, or your current selection.
3. Pick a workflow: create missing joins and put the cut order right, cut geometry, switch the order of existing joins, repair joins, unjoin, or remove existing cuts.
4. Choose how the cutter is decided: by rule order (left cuts right), by category priority, or by a numeric parameter on the elements.
5. Add Geometry rules: each rule pairs two categories, and you can narrow either side to a family or a type. Only pairs that match an enabled rule are touched. The swap button flips which side cuts.
6. Click Preview to see every planned change - counts, timings and a pair-by-pair list - without touching the model.
7. Click the run button to apply. Results appear on the Results tab, and the whole run is one undo step in Revit if you change your mind.

Good to know

• Six workflows are included: join and enforce order, cut geometry, switch the order of existing joins, repair joins (unjoin and rejoin), unjoin, and remove existing geometry cuts.
• Nothing is joined or cut on a near miss. Elements that merely sit close together are only candidates; a join or cut happens only where the elements genuinely intersect or share a face, and everything rejected by that check is listed so you can see why.
• Cut geometry only applies where the elements truly overlap. Pairs that clash but can't be cut are reported as unsupported instead of being changed.
• An All categories wildcard can stand on either side of a rule, and the plugin warns you before an all-to-all scan of a full model so a heavy run is never a surprise.
• Your rules and settings are saved with the plugin, so the setup you refine for a project is there the next time you open it.
• The results report shows what was planned, what was changed, what was skipped or rejected, how many elements were scanned, and the exact element pairs behind any issue.
• Large runs are processed in batches for speed, but Revit still records the whole run as a single undo item.
