Rhino: Rubber Duck

Today we're going to learn a few new tools and techniques to build a Rubber Duck. If you need to follow a printed tutorial later, you can check out The Training Manuals online (see previous post).  Today we'll be using Rhino Training Manual Level 1 [pages 156-169].  Following a tutorial from a book [particularly an online book] can be difficult, so I will work through this one with you as well.

The Basics (see illustrations below):

1. Create two spheres (head and body) in the RIGHT viewport
2. Select both spheres and type REBUILD
3. Set dialog for 8, 8, 3, 3, Delete input, ReTrim, OK
4. Select the body (or de-select the head)
5. Turn Control Points on (F10)
6. Select the bottom 1/3 of Control Points (on the body)
7. Go to TRANSFORM > SET POINTS and Set Z and Align to World
8. Drag upward to have a flattened bottom of the ducks body
9. Drag around some control points to select them and stretch the body to look more "duck-like" (i.e. puff out the chest, pull out the tail shape, etc.).
10. Turn Control Points off (F11)
11. Select the head (sphere)
12. Follow the same select > drag/stretch to form the bill and head shape
13. Right click on RIGHT to select Ghosted as the view type
14. Draw a curve (I usually use the free sketch curve) COMPLETELY intersecting the head shape
15. De-select everything and type SPLIT
16. Follow the prompts by selecting the object to split (the head) and then the cutting object (the curve)
17. The bill and head should now be separate objects so you can color/texture them as you wish
18. Draw a straight line cutting through the base of the head
19. Copy and paste the straight line, then drag it to intersect the top-right section of the body (copying and pasting keeps the lines perfectly parallel)
20. Type TRIM and select the pieces to trim (or delete) and press ENTER when finished
21. Go to SURFACE > BLEND SURFACE 
22. In the Perspective window (I find this is the easiest to work with in this step) select the first edge of your cut object then press ENTER
23. Select the second edge (the other cut object) and press ENTER
24. Check the PREVIEW box and adjust the "bulge" to look its' best 
25. Add colors/textures/gloss 
26. Add some shapes (i.e. spheres, ellipsoids (flattened spheres), etc.) to create eyes.

Please Note:  I am trying to teach you the basics of editing shapes (split, trim, blend, etc.) and not necessarily how to build a rubber duck -- so experiment and have fun with it.  You don't have to have a duck that looks exactly like mine [in fact I like creativity].  Here are some examples of creative ducks.  :)
