Open your design in Silhouette Studio®. Make sure you design is ungrouped so certain lines may be assigned to certain tools.
Load your first tool into Tool 1 of the carriage holder (the holder farthest to the left).
Repeat for your second tool into Tool 2 on the right.
Place your material on your mat and load it.
Go to the Send panel. Choose your material.
Assign which lines you want to cut with which tools. To do this, select the lines on your design page and then click either Tool 1 or Tool 2. Adjust your action to match the tool you loaded into your tool holder.
Send your design to your Silhouette. Unload your project when it has finished with both actions.
