During placement, or after placing components, use the shortcut key <R> to Rotate them and <F> to Flip (mirror) surface mount components to the other side of the board. These options (and more) are available on the shortcut menu during placement by clicking the right-hand mouse button.
TO FLIP (MIRROR) COMPONENTS TO THE OTHER SIDE OF THE BOARD
For our example design, no mirroring (Flip) will be required. The placement and overall connection lengths could be improved by rotating some of the components. If you feel you would like to practice placing components, select a component and click <R> to rotate it. Component names can be rotated back to be a readable direction separately using the same pick and rotate method.
