This screen is used to modify the camber of an airfoil. Camber cannot be altered for symmetrical airfoils as these have no camber. Camber is expressed as a percentage of the chord of an airfoil. The location of the point of maximum camber can not be altered by this screen.
To modify the camber;
Enter the amount of camber and click on the OK button.
To exit without making a change, click on the CANCEL button.
The RESET button is used to reset the camber to the original camber for the airfoil.
Tip To undo your change , click on the 
on the AIRFOIL CAD toolbar.
Warning The modification of existing airfoils is not recommended. Without a thorough knowledge of aerodynamics and extensive wind tunnel testing modifications will in most cases reduce the performance and could lead to poor aircraft flight and stability characteristics.
