Multi-KDR
Opening several KDR files is possible thanks to the “multi-KDR” mode in Patchwork Explorer.
With the “multi-KDR” mode, you can add products from other databases to the list of products available in the Viewport Manager.
When the "multi-KDR" mode is deactivated, the list of products available in the View Manager is limited to the products in your KDR file. Once the "multi-KDR" mode is activated, you can add products from other databases to this list.
This gives you the possibility to stage together or compare side by side products found in different KDR files.
To add products from a different database, return to the File menu to open a new database. Products in this new database will be added to the list of products available in the Viewport Manager.
