If an entity is linked to a template, it is possible to locate its template by right-clicking on the entity and selecting “Show Template”. If the template can be located, it will get focus in the Templates tab and be selected.
It is possible that the template may not be located. This is likely where the template entity is on a template server, and the template server has not been connected to and has not been refreshed. In such a case, a message will display indicating that the template entity could not be located.
If this happens, connect to the template server and refresh it, and attempt to Show Template again.
