Some time ago , I was a teacher trainer , teaching them to work with Trimble Sketchup as a useful tool that could be used in the classroom with children from 10 to 18 years of age. At that time created a support blog with links and some useful information . Now I decided to give it a new look and introduce some general interest content for those who want to learn how to work with this program , as simple but allowing to do so much . It is written in Portuguese language , so you have to learn it first! http://sketchupemportugues.blogspot.pt
