Engineering Design Graphics
Spatial visualization skills and attention to detail can be effectively improved using various specialized methods. Starting in the 1990’s multiple researchers observed that improving 3-D visualization leads to better performance in engineering graphics and in most other engineering coursework resulting in improved retention and graduation rates. There are multiple methods used to help students improve their 3-D visualization skills using objects in isometric views, or folding patterns, or objects to be mentally manipulated, reflected, or rotated. Other exercises present real 3-D objects that are easily recognizable in multi-view projections with missing views asking students to correlate the 2-D images with the ones in 3-D and find the missing view. The newly proposed method uses a different approach. It uses the standard multi-view projections to show a number of rectangular bricks arranged in various patterns. The viewer must count the exact number of bricks that form the structure. To do this the viewer must visualize each brick in its 3-D arrangement and count it only once despite the fact that the same brick may show up in more than one view. The major advantage of this method is that it does not require any prior engineering graphics training which makes it suitable for the opening classes of any graphics course. This method was used for over nine years with demonstrated success for students with a wide variety of visualization skills. It is intended as a tool to help Engineering, Architecture, and Art students and faculty who want to increase their 3-D visualization skills and improve their attention to detail.
