Congratulations! You have completed the joystick model and have gained experience in using curves and then surface tools to build freeform shapes.

Important concepts to take forward to future modeling projects are:

• On a curve, a minimum of 4 CVs are needed to create the curve. Adding more CVs means that the curve can have a more complex shape.
• Construction history means that you can modify the shape of a surface by changing the curves it was built from.
• Alternatively, you can turn on the CV display for the surface and modify the surface CVs directly to change the surface shape.
• The Control Panel can be used to display or hide the CVs of a curve or surface.
• It is good practice to turn off the CVs on objects that aren’t being modified, to reduce the complexity of the view on the screen.
• Regularly save your work!
