Simple animations, frame by frame

Marcelo Valderrey

73 0 Beginner
There are many efficient ways to make animations from CAD models, such as those created in the SolidWorks Motion module. However, simple animations, created frame by frame, are still very useful because of their flexibility to be edited with graphics and text, manipulate their timing and transitions, etc. This tutorial provides some tips for creating animated giffs in PHOTOSCAPE from images taken from the SolidWorks screen.

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.

Analogies are always imprecise, but let’s risk one that equates a car with a numerical simulator, with their respective internal machinery “under the hood.”

DOF in engineering problems (1)

Marcelo Valderrey
in Theory
71 4 Intermediate
A reflection on verbal and visual skills to take advantage of the "degrees of freedom (DOF)" present in engineering problem statements. To this end, some results of the challenge posed are used as an excuse to address these ideas: https://grabcad.com/groups/weekly-challenge-group/discussions/a-mechanism-to-move-the-green-orange-rectangle

Our working memory and its storage in sketches

Marcelo Valderrey
in Theory
71 0 Intermediate
Why so much insistence on low-level functional sketches? Because they are the ideal complement to the wonderful, but limited, working memory of our brain.

LEGO - 01 Basic Dimensions & Bricks Explained

dk
in Modeling
71 9 Intermediate
I get a lot of questions about how I create LEGO parts. This is Part I - The Basics. Most "standard" parts can be created using only simple math. Standard parts consist of square, circular, and angled blocks - regular geometric blocks. I will refer to BrickLink (www.bricklink.com/), but many others use similar methods: Peeron: http://www.peeron.com/ BrickOwl: http://www.brickowl.com/ Brickipedia: http://lego.wikia.com/wiki/LEGO_Wiki etc.

Equipos fundamentales de un desbaste alternativo

Marcelo Valderrey
in Theory
70 0 Beginner
Este tutorial muestra los tres equipos principales de un desbaste alternativo para laminación en caliente: a la salida del horno se ingresa en una mesa de guías volcables que orienta el material hacia los distintos canales de un stand (o columna) trío. Del otro lado es recibido por una mesa basculante que lo toma del nivel superior (entre el cilindro medio y el superior) y lo reencauza en otro canal a nivel inferior (entre el cilindro medio y el inferior). En otros tutoriales se hace hincapié en tríos y dúos de laminación, pero este en particular se enfoca en la mesa basculante (y diversas modificaciones mecánicas, hidráulicas, etc. para alcanzar mayor confiabilidad y productividad).
