Check Spelling

Check Spelling scans your documentation text — Text Notes, Room names, Sheet names, View names, and Tag text — against a Hunspell dictionary and lists every unrecognized word with suggestions. Pick the dictionary language, scope the run to the current view, to sheets (optionally a single Sheet Set), or the whole project, and choose which of the five sources to include. For each flagged word you can edit or pick a suggestion and Apply it back to the model, Ignore it (remembered for this project), or Add to Dictionary (kept for every project). Results open in a review grid with checkboxes for batch actions, a status badge per row, and a Highlight button to locate the element. The window is non-modal, so you fix and keep working.

1. In the B45 Labs | Coordination tab, open the Documentation panel and click Check Spelling. The window is non-modal.
2. Choose the dictionary Language, set the Scope (Current View, Sheets, or Entire Project), and tick the Sources to check — Text Notes, Rooms, Sheets, Views, Tags.
3. Click Run. Each unrecognized word appears as a row with its location, source, and the engine's suggestions.
4. For a row, edit or accept the suggested word and click Apply to write it back — or tick several rows and Apply them as a batch, each with its own suggestion.
5. Use Ignore to dismiss a word for this project, or Add to Dictionary to accept it everywhere; Highlight jumps to the element in the model.
6. Clear Resolved tidies the list; Export / Import Dictionary moves your accepted words between projects as a .txt file.

• Match the dictionary Language to the document's language for meaningful results; the checkbox Sources let you focus a pass on just sheet or view names, for example.
• Ignore is remembered per project (it persists in the .rvt), while Add to Dictionary is shared across every project — use Add for real domain vocabulary, Ignore for one-off proper nouns.
• Words already in Revit's own dictionaries (RevitENU.dic and Custom.dic) are treated as accepted, so approved Autodesk terms aren't flagged.
• Build a house glossary once and carry it between projects with Export / Import Dictionary.
