Google sketch-up is a program that allows you to create 3-D objects. You are able to build 3-D objects and see every angle you wish to see. It is easy to learn, and not hard to make objects. The tools are easy to use as well. If you understand what the tools are there should be no problem. The tools icon aren't hard to understand it is pretty simple, but there are so that may be confusing. Other than that it is pretty simple. If you are really good you can make anything on there and see a 3-D view of it. Google sketch-up can be a useful tool if your work require you to make blueprint. It is also very fun to do. To can have fun doing it, but it not something you'll do all the time though. That is what I learned about Google sketch-up.
