There does not exist a specific reuse element type but rather it is possible to enable the reuse possibility for almost every element in AF3.
Currently, the following AF3 elements are supported in reuse libraries:
Components
Tasks
Requirements
Functions
Structures
Enumerations
If you think an AF3 element is missing for reuse, please contact the AF3 developer team.
If one of the AF3 elements above is added to a reuse library, it is now possible to reuse it from the reuse library and insert it again in the same project but also in other projects of the same workspace or even of other workspaces (see here).
In addition, it is possible that you (or another AF3 user who got the referenced reuse library from you) modify the reused element in another project/environment and update the connected reuse element inside the referenced reuse library with this modification (see here).
If the updated reuse library is then brought back to your workspace (or was already there all the time), you have the possibility to propagate the modification of the somewhere else reused element to your original AF3 element by updating this reuse element via the modified reuse library (see here).
