• Resumen

  • This paper presents a comparative analysis of the multi-view drawing of a simple geometric component by using a traditionalisometric-view drawing and a three-dimensional model generated by additive manufacturing. The study was performed during aone-year period encompassing two engineering drawing course groups of 30 students each, with no gender distinction. Theexperimental work analyzes fundamental aspects of engineering drawing such as the correct selection of frontal auxiliary’s views,hidden lines, dimensioning under ISO standard by employing and evaluation rubric with four weighting levels. From the results, itcan be observed that the use of physical three-dimensional models allows students not only to have a better comprehension of thegeometric projections of objects but also to strength the hands-on skills required in the engineering educational programs.
