When you open a previous version of a catalog or a project file, the software prompts you with the Open Catalog or Open Project upgrades message box. These message boxes enable you to upgrade the previous version of the file to the current version of the CADWorx Structure Editor.
Upgrade
Upgrades the selected file and makes it incompatible with older versions of the Structure Editor and CADWorx Structure. This upgrade places any new features into the original file.
Save backup & Upgrade
Saves a backup of the original file and upgrades the selected file to the current CADWorx Structure Editor version. You can continue to use the original file in the previous version of the Structure Editor, or any version of CADWorx Structure, by removing the .bak from the file extension.
