PLAYIN' in the sandbox

I spent a few hours exploring the Sandbox feature in Sketchup this
weekend after reading this book. Sketchup has again shown what a
powerful simple tool it is. Now it's not going to be as robust as
Zbrush or Mudbox but it is a nice terrain modeler with a few hidden
features.
The first is changing the area of influence

but you can also select

points

lines

surfaces

and multiple selections of each.

So, you can model with the circular brush or pick only what you want to shape.

Here's a simple mountain I made. Again, other programs are going to
have a lot more perameters to work with but this , like the whole
program, has lots of hidden power.
