A representation of a simple object can not be easily solved in all cases. Some of these exercises are useful in an early stage of formation of our students, as they show the difficulty of unequivocally represent objects whose spatial restitution is accurate.
I set out to solve a problem with a curious piece of technical drawing that was determined by two of its projections.
One of the classic exercises that start in high school is that of obtaining a three-dimensional model from two or more given views of an object.
Objects or initial parts tend to be basic and composed of flat surfaces. In general, the space they occupy is limited to a small cuboid.
Through this exercise stimulates the so-called “spatial vision” Student, looking to learn how to “read” and “To write” graphically representation of volumes.
Las piezas que usamos en las primeras etapas formativas suelen tener caras paralelas a los planos de proyección. Estas características permiten que su representación se realice recurriendo únicamente a los planos básicos, horizontales, verticales y/o de perfíl.
En aquellos casos en los que existen elementoa oblícuos deberemos realizar representaciones basadas en vistas auxiliares (simples o múltiples) de forma que en alguna de las representaciones se puedan apreciar en verdadera magnitud el ángulo que forman entre sí estos elementos oblicuos.
The pieces in 3d that we are presenting, mostly, come from representations of real objects with functionality in mechanical assemblies. Identifying your working position can help us find the main view of the object, that will determine the most complete information of the same. One or more additional views, profile, the front auxiliary views, will end up defining the shape and dimensions of the object.

A new 3D mechanical part, which can be defined from a main view to determine the flat shape and position of the accommodation on it. An additional view, the front profile, terminará de definir la forma y longitud de los resaltes y agujeros.Deberemos por lo tanto representarla según las normas de… (leer más)
An interesting piece in 3d mechanical, useful mechanical transmission systems. We will represent it by the standards of technical drawing and select the necessary views for definition.
We continue with 3d mechanical parts, increasingly complex, for implementation by the standards of technical drawing: A normalized representation exercise anchors support for other parts to a bench.
Solution to the thirteenth piece of technical drawing.
They have represented the three main views (plant, elevation and profile) conducting student leaving the new views (not necessary for the representation of the object).
Between the two possible profiles, We used one containing a smaller number of hidden lines.
Solution to the fourth piece of technical drawing.
They have represented the three main views (plant, elevation and profile) conducting student leaving the new views (not necessary for the representation of the object).
Between the two possible profiles, We used one containing a smaller number of hidden lines.
A new piece for our collection of exercises in mechanical in 3d, for implementation by the standards of technical drawing: An exercise normalized representation of a support for a shaft or cylindrical.
