Dimensions / Cotas

Dimensioning a drawing means adding dimensions, notes and lines to a drawing.
Architectural, Engineering and Design drawings must be able to tell you everything you need to manufacture a component or assemble several components together.
Basic Types of Dimension Used in Engineering Drawings.

You have to know:

• Basic rules of dimensioning.

• Types of lines. (for part, projection/extension, dimension and leader lines).
• Types of dimensioning a drawing (parallel, running, chain, and combined).

• Dimensioning circles.
• How to dimension a radius.
• Notes.

Acotar un dibujo significa añadir cotas, notas y líneas al dibujo.
Los dibujos de Arquitectura, Ingeniería y Diseño tienen que aportar toda la información necesaria para poder manufacturar o construir un objeto, pieza o ensamblaje.

Tienes que conocer:

• Las reglas básicas de acotación.
• Tipos de línea. (para las líneas auxiliares, línea de cota, cotas y flechas)
• Tipos de acotación. (en serie, en paralelo)
• Acotar círculos.
• Acotar radios.
• Textos

• Ejercicios para medir y acotar. Los vamos a hacer a mano con regla y con ordenador.
• Measuring and dimensioning exercises. You will do them with rulers and with computer.

Parallel and perpendicular lines

How do we use the set squares?

You have to handle your set square softly and with accuracy without too much pressure on them, only the needed one to avoid movement.

PARALLEL LINES

1. The 45 set square hypotenuse (longest side) is placed attached to the line to which we want to draw the parallels (GUIDE).
2. The 60-30 set square hypotenuse is attached to the 45 set square leg.
3. Fix the 60-30 set square and move the 45 set square upwards or downwards drawing the desired parallel lines along its hypotenuse.

PERPENDICULAR LINES

If we want to draw perpendicular lines to one direction, we will have to follow the first two steps as stated for parallel lines and then the following ones:

1. Having fixed the 60-30 set square, the 45 set square is turned until the other leg is attached to the hypotenuse of the 60-30 set square.
2. Draw the perpendicular line along the hypotenuse of the 45 set square.

Let's review how to draw parallel and perpendicular lines using the triangular set squares.

Eva A., 1st A (former student) recorded, some years ago, a video at home for us. It is GREAT!!!!

Thank you very much Eva.

Technical Drawing: Sketch-Draft-Drawing

• Sketch is a rapidly executed freehand drawing often consisting of a multitude of overlapping lines that is not intended as a finished work. 
• Draft is an early version of a drawing with dimmensions. 
• Plans are the final version of drawings of objects with all the information needed to be built or constructed.

• Bocetos
• Croquis
• Planos

Pencil scale

You will need:

1. 2H or 3H pencil - for technical drawing, lines with ruler
2. HB pencil - for writing and handmade drawings: sketches and draft

Drawing tools

• Basic drawing equipment A.
• Basic drawing equipment B.
• Basic drawing equipment C.
• Basic drawing equipment D.

• Titles, subtitles and labels: Improving the standard of presentation of design sheets.

VOCABULARY TASK

• Vocabulary exercises 1, 2 and 3. Just in case you need a new copy. Use links above to complete the exercises. Common office equipment is not in these pages, so do it by yourself or search on the Internet (I think they are only 3 or 4 items). Please, only short and easy descriptions, remember you have to learn them.

Paper sizes

• The International Standard ISO 216 (International Organization for Standardization), sets out the common paper sizes used around the world. 
• 161 countries from around the world are members of the organisation.
• The metric system of paper and card sizes are shown below. 
• All ‘A’ sizes are double the previous size, with A0 being the largest.
• Paper types and weight: origin, weight, color and thickness. - g/m2 -

• La norma ISO 216 de la Organización Internacional para la normalización (International Organization for Standardization), especifica los formatos de papel que se usan en mucho países del mundo. 
• 161 paises son miembros de esta organización.
• El sistema métrico de papeles y tarjetas los encontrarás en el dibujo de abajo. 
• Todos los tamaños ‘A’ son el doble del tamaño anterior, y el A0 es el mayor de todos.
• Tipos de papel y gramaje: origen, peso, color y espesor o grosor. - g/m2 -

En España se han ido sustituyendo los tamaños que había por los DIN-A, y que eran ligeramente más grandes:

• DIN A1 < pliego
• DIN A2 < medio pliego
• DIN A3 < pliego pequeño
• DIN A4 < folio o medio pliego pequeño
• DIN A5 < cuartilla
• DIN A6 < octavilla

• Paper sizes tasks.. Pages 2 and 3 should be done in your notebooks. Haremos las páginas 2 y 3.
• REALIA: Craft Practice Using sheets of paper (A4). Create A3, A2, A1, A5, A6, A7... formats.

Technological project

Definition of a technological project: 

The different activities carried out since one problem arises until we are able to solve it. 

This method of work consists of the following steps:

1. NEED
   Define the problem: the situation that need to be solved is clearly defined.
2. IDEA
   Look for solutions: searching for information, analyzing similar objects, raising different solutions and choosing the most appropriate one.
3. DEVELOP THE IDEA
   Design the object: in this step the idea is set and it is described in written and graphic form.
4. PLAN THE CONSTRUCTION
   Planning: it has to do with anticipating the jobs that are going to be carried out, handing out the job, obtaining the materials and preparing the tools.
5. CONSTRUCTION
   Construction: it is necessary to manufacture the different parts separately and later put them together.
6. CHECK
   Evaluation: one tests how the object works and corrects the design if necessary.
7. TECHNICAL REPORT
   Communication of results: it is necessary to present a technical report in which one describes the whole process.

What is an Avatar?

In computing, an avatar is the graphical representation of the user or the user's alter ego or character. It may take either a three-dimensional form, as in games or virtual worlds, or a two-dimensional form as an icon in Internet forums and other online communities.

Your avatar is the small picture that appears along with your user-name when you participate in activity on the site. The avatar is also seen above your user-name on your profile page. Many people use a flattering picture of themselves as their avatar, but you can use any picture you want as long as it isn’t offensive. An avatar gives other users a “face” to go with your user-name. They will recognize your avatar when you participate in activity on the site like commenting on articles, posting in the forum, and making new friends.

Some ideas to create your own avatar:

• Portrait Ilustration Maker: 
• ArtisanCam.

• Face your manga. 

• Bloc head Iconizer: 

• Paper Critters: To design whatever you want!

• Pocoyízate. Pocoyó. In Spanish.

• DoppelMe: Very easy

Some usuful tools you may need:

• Recortes. If you have no option to download your avar, take a screenshot. "Recortes" es a tool you will find only in Windows. Choose a rectagular shape, select your avatar and save it.

• A different way of taking a screenshot: CAPTURA DE PANTALLA
