In this lesson you learn how to:
Create a NURBS curve using the control vertices (CV) creation technique.
Use the grid for visual reference when modeling.
Determine the start and end points for a NURBS curve and its direction.
Create a revolved NURBS surface using the Revolve tool.
Change the display shading smoothness for a NURBS surface.
Edit a NURBS surface by editing its initial profile curve when it is linked
to the surface by construction history.
Creating a profile curve
Revolve is a common modeling technique similar to shaping a vase on a
spinning potters wheel. You must first create a profile curve in an orthographic
view and use the Revolve Tool to create a surface.
To create a profile curve
1 Make sure youve done the steps in
Preparing for the lessons on page 149.
2 Select Panels > Layouts > Four Panes so you can see multiple views of the
scene.
3 Select Create > CV Curve Tool.
This is the most commonly used tool for drawing curves.
