Select a long, rectangular block. Lay it in the center of the screen. Lay another one a few spaces away from it. This creates the seaplane's landing gear.
Build the seaplane's hull using large, round pieces. Build the dual wings so that they come off the hull.
Place a propeller on the front of the hull.
Send the seaplane's design to LEGO by clicking "Upload." Buy the design by selecting "Check Price." If you decide to buy the seaplane, the design is sent to your house, where it comes with instructions on how to build it.
