Some drawing properties are saved in the project (for example: annotations). Those properties are then available to other drawings when they are synchronized. You can synchronize drawings automatically when they are opened, or by refreshing in Project Manager.
Automatic synchronization is set with synchstylesmode.
Audit a project to search for errors, such as links between non-existent properties or discrepancies in the tag registry.
A log file describing problems and the actions you can take to resolve them is added to the project directory that contains the data cache.
Periodically compress a project to optimize performance and efficiency of the project. Compressing a project defragments the drawing data cache, repairs any inconsistencies, and prevents corruption of the cache.
