Again the symmetries appear in technical drawing parts, which should lead us to seek representation techniques that allow to use this feature recurring engineering. The axes of symmetry. axes represented as circles with small marks at the ends, allow us to represent only one of the parts of the object. La forma en… (leer más)
A new piece which is defined “within” the volume of a cylinder of revolution, present a limited view of the cylinder by projections container. Material parts are eliminated give rise to “cajeados” can not exceed the dimensions of the cylinder. Especialmente son interesantes aquellas proyecciones en las que se ve el contorno… (leer más)
As every year, Professor Jaime Rua, junto con la profesora María Jesús Casati nos regalan unas simpáticas imágenes del concurso de puentes de palillos que realizan con los alumnos de tercero de la especialidad de “Airports” technical aeronautical engineering. Una clase en forma de concurso de alto interés pedagógico que cierra un… (leer más)
The two planes oblique views to be defined in the projected perpendicular to the plane of projection, so that the angle formed with the horizontal plane is in them in true scale. Although the plan view is almost always a top view of the object, en este caso sería… (leer más)
Las piezas formadas por superfícies (planes) paralelos a los del triedro de referencia son más sencillas de representar que aquellas que presentan planos inclinados. La utilización de líneas auxiliares para identificar las posiciones de los vértices de la geometría puede ser un recurso de gran valor en el análisis de las proyecciones normalizadas de estos… (leer más)
Need a revolving element that defines an elevation profile or contour has been obtained from the subject, except that by dimensioning can define circular (The symbols in the radius or diameter). Si de dispone de una vista del objeto en la que se vean en verdadera magnitud las… (leer más)
Only simple parts can be represented by a pair of orthogonal views. As complicated geometry we need new projection directions to determine all the details of the object. Oblique planes should be projecting in any of the views chosen to determine their slopes; Las circunferencias deberán observarse en verdadera magnitud… (leer más)
In this new piece “edges kill” via a transition surface between two planes. The cylindrical shape is tangent to adapt to these planes. In addition the cylindrical body has perforations or “Drills” que serviran de guía y apoyo de elementos como pernos, screws, axes … The bottom has a shape of “cola de… (leer más)
Objects that have oblique planes are more difficult than those in which the planes are parallel to the reference trihedral (we use to “deploy” the representation plane). We define the views so that each element oblícuo, each angle, remaining defined by at least one of the views represented. Analizar estos… (leer más)
The object has been created from a unitary dimension cube, used its vertices and its geometric center to define the faces of the new object. Oblique planes hence are well defined from the initial volume. This conceptualization of objects (que se basa en idearlos a partir de modelos más… (leer más)
As the object becomes complicated form, a simple projection can not give us enough information about the object that we want to represent. His interpretation may be ambiguous and need to new views that complement, that allow us to “return” form. Si somos capaces de realizar una representación correcta y completa del… (leer más)
