The body and head of the ducky are created by modifying two spheres. The size and placement of the spheres doesn’t need to be exact.
1 From the Solid menu, click Sphere, then click Center, Radius.
2 At the Center of sphere prompt, in the Front viewport, pick a point.
3 At the Radius ( Diameter ) prompt, pick another point in the same viewport to create a sphere as shown.
4 Repeat this procedure for the second sphere.
Notice that you have sharp edges in the sphere. To make them smoothly deformable, you must add control points and thereby the ability to deform smoothly.
6 Click in a viewport to
exit shaded mode.
7 Press Esc to turn off
control points.
8 From the Edit menu, click
Undo.
9 Press Esc repeatedly repeatedly
until control points are off.
Change the Degree to 3 for
both U and V.
Check Delete input.
Clear Current layer.
Click OK.
Having more control points
allows more control over smaller parts of the surface. A degree-three surface
will have a smoother shape when deformed.
