About Keynoting versus Tagging a Material

The difference between keynoting and tagging a material is the information that is displayed in the tag and which tag family Revit LT uses. Revit LT has separate categories for keynotes and material tags.

Using keynotes

• When you use a material keynote, Revit LT 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 tabTag panelKeynote drop-down (Material Keynote).

Using tags

• When you use a material tag, Revit LT 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).
