Need to convert an STL (or OBJ) file into a "real CAD model"? There are several tutorials which already exists for this topic. I'm making a new tutorial to give additional information.

Creativity in engineering - Part 4 (English version)

CPDC: Conceptual Postprocessing Divergent Convergent. This tutorial describes a relevant task within the conceptual engineering process that consists of post-processing the SSC (Spectrum of Solution Concepts) to understand and classify the solutions achieved, and deepen the learning of the problem. Its objective is to obtain new solutions, either by association of pre-existing ones, by the discovery of conceptual omissions or by a crisis of ideas and paradigms that induces the breaking of molds and the appearance of disruptive concepts. In order to properly contextualize this task, all the milestones of the conceptual stage are reviewed, highlighting the moment in which the CPDC is executed and glimpsing its relevance.

The following comments are based on an example (https://grabcad.com/library/g-train-1) that is in its early stages of conceptualization and that is not intended to focus on "the technical benefits of a solution" but on "the correct work methodology" in conceptual engineering, timely attending to aspects related to wealth/diversity/divergence of thought:

Animaciones sencillas, cuadro a cuadro

Existen muchas maneras eficientes de hacer animaciones a partir de modelos CAD, tales como las creadas en el módulo Motion de SolidWorks. Sin embargo, siguen siendo de gran utilidad las animaciones sencillas, creadas cuadro a cuadro, por su flexibilidad para ser editadas con gráficos y textos, manipular sus tiempos y transiciones, etc. Este tutorial brinda algunos tips para crear giff animados en PHOTOSCAPE a partir de imágenes tomadas de la pantalla de SolidWorks.

Cap screws and machine screws

dea
in Drafting
67 12 Intermediate
Cap screws and machine screws are similar in shape, differing only in their relative sizes. Machine screws are usually smaller in size, compared to cap screws. These are used for fastening two parts, one with clearance hole and the other with tapped hole. The clearance of the unthreaded hole need not be shown on the drawing as its presence is obvious. Figure 5.24 shows different types of cap and machine screws, with proportions marked Cap screws are produced in finish form and are used on machines where accuracy and appearance are important. As cap screws are inferior to studs, they are used only on machines requiring few adjustments and are not suitable where frequent removal is necessary. These are produced in different diameters, upto a maximum of 100 mm and lengths 250 mm. Machine screws are produced with a naturally bright finish and are not heat treated. They are particularly adopted for screwing into thin materials and the smaller ones are threaded throughout the length. They are used in fire-arms, jigs, fixture and dies. They are produced in different diameters upto a maximum of 20 mm and lengths upto 50 mm.

Los siguientes comentarios se basan sobre un ejemplo (https://grabcad.com/library/g-train-1) que se encuentra en sus primeras etapas de conceptualización y que no pretende enfocarse en "las bondades técnicas de una solución" sino en "la correcta metodología de trabajo" en ingeniería conceptual, atendiendo oportunamente aspectos relacionados a la riqueza/diversidad/divergencia de pensamiento:

Conceptual Design of Dovetail Joint

Marcelo Valderrey
in Theory
64 4 Beginner
Some solutions to the challenge posed by https://grabcad.com/steen.winther are presented: impossible dovetail joint? Each one starts their attempt from a particular situation, which can lead them to first find a solution (such as the rectilinear one) and later others (such as the circular ones). What this tutorial intends is to show the style of conceptual thinking that allows "discovering the rules behind particular cases" to conclude that all possible solutions actually derive from "the same idea". Note: this type of challenge is useful for those who do not know the solution or other similar cases. The idea is to force the process of generating and evaluating ideas. Once you know the case, the opportunity to discover solutions is lost!
