Tree Bien

Creating a tree with curves.

This was a great tutorial that taught me a great skill; how to use a bezier curve as a shape and not just something to map onto a pipe...

If you set the width of the curve up a bit you can see it. I just duplicated and extruded, as well as altering the radius size with ALT-S. It looks great and was surprisingly simple to create.
