First, determine the shape of your pool dome or pool cover as described in measuring directions. Once you have established marked your "points" and created the shape you want you are now ready to setup the A-B line for measuring.
Now, setup you "A-B line" by creating two points, A & B, located at exactly 20' apart and 3' away from the long edge of your shape. For simplicity, it often works best to setup the line parallel to the long axis pool, as seen in the diagram above. If you have any questions about setting up, please give us a call at 800-982-6966.
