3DVinci, a producer of three-dimensional design project materials that blend left-brain analytical skills with right-brain creativity, recently announced the updated version of ModelMetricks, a series of books for ages 8 - 15 that use free software to teach K-12 students to visualize, create, and analyze in 3D. Projects are based on Google SketchUp, an easy-to-use 3D design application. ModelMetricks' products help students learn to do 3D design projects for a variety of academic disciplines. The ModelMetricks project-based approach enables new users to create their first designs in SketchUp within a few minutes.
