Today, new versions of Sketchup (3D modeling) and Layout were released, and they look amazing. I started using Sketchup this past summer, it is easy to get started, has many advanced options, and there is a great 3D warehouse of models. If you are an educator, you maybe able to get an educational discount, which means you'll get the $500 pro version for free, which I have. I just love how Google supports the educational system. My plans for Sketchup and Layout are to create 3D models and figures for my lab manual (replace the 2D ones), and hopefully avoid the use of the advanced, but very confusing Corel Draw. Check out the video below for the new Sketchup features.
