Keynoting in Revit: Setup and Best Practice

Keynotes can make a busy detail much cleaner, or turn it into a puzzle if the setup isn't right.

Keynoting replaces long text notes with short codes linked to a central list of descriptions. In Revit, keynotes keep wording consistent across a project and make it easier to align notes with specifications.

How Revit keynotes work

Revit reads keynotes from a text file, typically tab-delimited, containing codes, descriptions and parent groupings. Keynote tags can display the code, the description or both. Keynote legends list the keynotes used, either on the whole project or on each sheet.

Types of keynotes

  • Element keynotes: read from the element's type
  • Material keynotes: read from the material
  • User keynotes: chosen manually for a specific tag

Element and material keynotes stay consistent automatically, while user keynotes offer flexibility.

Structuring the keynote file

Many firms organise keynotes by specification section, such as CSI MasterFormat in the US or NBS or Uniclass-based references in the UK. This links each note to the relevant specification. Keep descriptions short and consistent.

Maintaining the file

  • Store the file in a controlled location
  • Assign an owner for edits
  • Keep a project copy if project-specific notes are needed
  • Review the file when specifications change

Revit can reference keynote files by absolute or relative paths. Make sure paths work for everyone, including remote and outsourced team members.

Keynote legends

Advantages

  • Consistent wording across all drawings
  • Easier coordination with specifications
  • Cleaner drawings with short tags
  • Faster updates when descriptions change

Challenges

  • The keynote file needs managing
  • Readers must look up codes in legends
  • Some consultants or clients prefer full text notes

Combining with text

Many firms use keynotes for most notes and text notes for unique, project-specific information. Agree the approach in the office standards.

Common problems

  • Broken paths to keynote files
  • Duplicate or outdated codes
  • User keynotes used where element keynotes would be more reliable
  • Legends not showing all codes used

Checking

Before issue, check that every keynote on each sheet appears in its legend and that descriptions are current.

Share keynotes with partners

If outsourced production teams or consultants work in your model, give them access to the keynote file and explain the structure. A shared file prevents notes being typed manually, which breaks the link to specifications.

Plan for regional differences

If the office works in several regions, consider separate keynote files aligned with each region's specification system, rather than one file that tries to serve everyone.

Keynoting takes some setup, but it pays off with consistent notes and a direct link between drawings and specifications.
