If the desired catalog has already been downloaded initially, you can update it anytime.
Call up the context menu in the directory tree on the desired catalog (right mouse button) and select the Download changed files in directories/projects from server [Download changed files in directories / projects from server] command under Version management [Versioning system].
-> The Update dialog box opens.
-> The changes are downloaded. Finally the index is updated.
-> The download process is logged inside the dialog box.
After a successful download, the message Done! [Ready!] appears in the dialog box.
Click on Close. You can now test the catalog in 3Dfindit / PARTdataManager.
