These models can be used for numerous reasons including: instruction manuals to show how pieces of an object are assembled, visualizations and animations to show concepts and plans for marketing purposes, and simulation studies to help model everything from tornados to how a new 10 story building will affect the sunlight on adjacent buildings. In this paper, two commonly used 3D modeling software applications, Blender and SketchUp, will be compared and contrasted. Introduction The 3D modeling programs Blender and SketchUp both allow three dimensional objects to be created, manipulated, and displayed. How these applications perform these tasks, along with costs associated with purchasing these tools, and best uses of these programs vary drastically. By knowing some of the strengths and weakness of these applications, the end-users can make a more informed decision – allowing them to be both more creative and productive. In particular, this paper will discuss the license agreements of these applications, the graphical user interfaces of these tools, and the drawing primitives each application supports. Finally, some overall differences and similarities between these two applications will be examined.
