10. A windshield for a motor bike

This exercise is designed to allow you to compare the results you can get by starting from the same curves and using two different tools. You will see that the surface skinning is different depending on the tool used.

1rst Method: Coons

2nd Method: Ruled Surface

Windshield (1rst Method: Coons)

Þ Step 1: Drawing (like method 2)

q Tool: 2D Drawing tool, Nurbs q Do it: Two NURBS curves make a closed shape. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Drawing

Þ Step 2: Making the windshield

q Tool: Hull/Coons q Open the model file: Coons2 q Do it: Select the Hull/Coons tool. Click on each curve; the surface is generated. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Surfaces/Coons Surfaces

Windshield (2nd Method: Ruled Surface)

Þ Step 1: Drawing (like method 1)

q Tool: Drawing tool, Interpolated Curve q Do it: Two NURBS curves make a closed shape. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Drawing/ Interpolated Curve

Þ Step 2: Making the windshield

q Tool: Ruled Surface q Open the model file: Coons2 q Do it: Select the Ruled Surface tool. Click on each curve; the surface is generated. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Ruled Surfaces
