Abstract
This paper describes the strokes, rotation, and modeling of an icosahedron in the orthogonal projection to produce a 3D print model, two cardboard models, and an augmented reality application with the same STL file. Each model and procedure - 3D print, stacked sheets, interlaced sheets, and the creation of a marker - required the utilization of different computer programs. Our study shows that the programs used to create the two cardboard 3D models and the marker modified the position of the 3D model in space from how it was originally saved in the STL file. On the other hand, for the 3D print, the position of the model was preserved according to the original STL file. This investigation determines that each program encodes the model’s geometry differently. Therefore, we conclude that the knowledge and application of descriptive geometry to troubleshoot 3D modeling issues is more important than any technological advances.
