The difference between keynoting and tagging a material is the information that is displayed in the tag and which tag family Revit uses. Revit has separate categories for keynotes and material tags.
Using keynotes
- When you use a material keynote, Revit looks for a tag family assigned to the keynote category. If the tag is not loaded in the project, you are prompted to load one.
- The keynote family displays one or both of the values available from the keynote table as assigned to the material's keynote parameter. If the material is not assigned a keynote, you will be prompted to select a keynote value when the material keynote is placed.
- To place a material keynote, click Annotate tab
Tag panelKeynote drop-down
(Material Keynote).
Using tags
- When you use a material tag, Revit uses a tag family assigned to the material category.
- The default tag displays the value stored for the material's Description parameter, if it is assigned.
- To place a material tag, click Annotate tabTag panel
(Material Tag).
