Abstract

The objective of this work is to propose the use of didactic material, to facilitate the teaching and learning of orthogonal projections in the international system. Virtual files of the projection planes are created: front, left side and bottom; as well as those corresponding to three versions of the same geometric entity: point, line, area and solid. The frontal plane is fixed, and the left side and bottom are restricted with respect to it allowing its rotation to coplanar all three. In the assembly of the projection planes, versions 1, 2 and 3 of the same geometric entity are inserted; each one respectively including its frontal, right lateral and superior projections; such versions are restricted with respect to the frontal, left side and bottom plane. The restrictions between the projection planes and between them and the versions of the same geometric entity allow the animation of the assembly, showing the solution of the problem that involves representing a three-dimensional object on a sheet. The augmented, virtual, animated, and timed reality environment; according to the learning needs of students and teaching of teachers; constitutes the main contribution of this work.
