Reloading the Cache
There are different ways in which you can reload the cache. If you want to reload a single reference, you can reload it from the Reference dialog, either by selecting the reference and clicking the reload icon or selecting Reload from the reset pop-up menu. You may also use the key-in REFERENCE VISIBLEEDGES CACHED SYNCHRONIZE <file_name>.
If you want to reload all the models within a file, reloading each reference separately can be time consuming. In such case, you can use the key-in REFERENCE VISIBLEEDGES ALLMODELS SYNCHRONIZECACHE.
