Hi and thanks for looking,

I want to model a letter 'B' for a logo project that I'm working on but am not sure if my approach is the right way to go, so to speak...

I would like the letter 'B' to start with a cube, and then animate as follows (so that it looks as if it was growing):

1) Extrude the top face up with 4 divisions... [ . -> l ] (and get a tall cube with five face rings)
2) Then extrude side faces 1, 3, and 5 to the side... [l -> E]
3) Divide the face of the middle side extrusion
4) Make two bridges to connect side extrusions 1 and 5 to the split face (made in step 3). [E -> B]

Is this possible? I have found it awfully tricky; e.g. once I do step 2, the side extrusions show up as soon as the cube animates up in step 1...

Is there a way to do this?
What is a common approach to growing things for expanding geometry?
How would you approach growing a letter 'B'

Thank you for any help, Tim
