Use this procedure to specify a keynote for a particular component of an architectural object by associating the keynote with the material definition for that component. The same procedure applies, whether you are specifying a keynote association for the first time or changing an existing one.
Note: If you change the keynote association for a material definition, it does not affect previously inserted keynotes for object components using that material definition. Those object components must be re-keynoted if you want them to reflect the newly specified keynote.
If you are establishing keynote associations for a number of material definitions that are included with AutoCAD Architecture 2023 toolset, you may find it most efficient to work from the material definitions drawing file (located at C:\ProgramData\Autodesk\ACA <version>\enu\Styles).
- Click
. 
- In the left pane of the Style Manager, expand Multi-Purpose Objects Material Definitions. Locate the material definition for which you want to specify a keynote.
- Select the desired material definition.
- In the Material Definition Properties dialog box, General tab, click Select Keynote.
- In the Select Keynote dialog box, make sure the correct database is displayed in the Keynote Database field (if you are using the default keynote databases, it should be Aec Keynote), and then select the desired keynote from the hierarchical tree view.
- Click OK twice.
The keynote is specified for the selected material definition and will be used for subsequent keynote insertions for object components with that material definition.
