But unlike the massive technical drawing reference texts on the market, Technical Drawing aims to present just the right mix of information and projects that can be reasonably covered by faculty, and assimilated by students, in one semester. Both mechanical and architectural projects are introduced to capture the interest of more students and to offer a broader appeal.
The authors have also created extensive video training videos, 26 hours total that is included with every copy of the book. In these videos the authors start off by getting students comfortable with the user interface and demonstrating how to use many of AutoCAD's commands and features. The videos progress to more advanced topics where the authors walk students through completing several of the projects in the book. The CAD portion of the text incorporates drafting theory whenever possible and covers the basics of drawing setup units, limits, and layers , the tools of the Draw, Modify, and Dimension toolbars, and the fundamentals of 3D modeling.
By focusing on the fundamental building blocks of CAD, Technical Drawing provides a solid foundation for students going on to learn advanced CAD concepts and techniques paper space, viewports, xrefs, annotative scaling, etc.
In recognition of t. The authors have also created extensive video training videos, 17 hours total that is included with every copy of the book. This type of art is one of the most striking and used by painters and illustrators today, so you can learn everything about it by consulting the Artistic Drawing Books that we have available in PDF and that will surely be very useful for you.

However, geometric drawing has a wide application, since it can be found not only in mathematics, but also in graphic design, architecture and other related disciplines. In that sense, we have made a selection of Geometric Drawing Books that will help you better understand its use.
You will learn how to draw circles, triangles, ovals and rectangles, and how to make compositions with them, including logos, faces and other more complex drawings. Mechanical drawing is quite similar to architectural drawing in terms of importance and responsibility since both are used as blueprints for later construction or, in this case, manufacturing.
Mechanical drawing focuses on the realization of robotic parts, machinery, automobiles, cranes, motorcycles, airplanes, helicopters and all kinds of industrial elements. It is used by professionals in the field and is usually done with specialized drawing tools or digitally.
Through the Mechanical Drawing Books, you will be able to learn all the basics of this art, as well as practice through the techniques described in the books. It is important to remember always to assessed. This does, however, usually turn measure only on the horizontal or vertical out to be a very small, tight drawing, and is axis - if you measure at an angle you will get not advisable unless you are very experi- distortions — and always measure with your enced.
The other way is to make a scaled arm straight out in front of you and from the drawing relative to your proportions; for same position to maintain consistency. Posture is the way we hold ourselves and has a direct relationship to the changing nature of proportion. As you can see in the example opposite posture is informed by directional lines that are determined by the angles of the body and the relevant proportions in relation to your body when you are in a pose.
Posture also allows us to understand and come to terms with the human form that exists in space on a two dimensional surface. The posture lines usually follow the central dynamics of the pose, and pick up the changing edges of the form on the main parts of the body.
You should always give lots of consideration to how you pose your model, because the posture will say so much about your drawing and what you are trying to achieve through it. One way of using postural lines is by extending them and in doing so one can find relationships that extend to other objects in a drawing. This is another way of making a drawing have proportional accuracy. It also creates an analytical directional tension in the drawing.
As you can see in this example it is shown by using a directional line that determines the angles and proportions of those angles relative to the other relationships of the body and their changing angles. Posture lines usually follow the central dynamics of the pose through the figure. They also pick up the changing edges of the form on the main parts of the body. The aim is to find of composing your picture and getting the associations by extending the axis from 10e objects in the scene proportionally and objects to locate other essential el0ments in positionally correct.
Cut the window to scale in relation to your paper. To do this and get accurate proportions in relation to your paper, follow these instructions. For example, if you want the height of your aperture to be three inches, mea 0 0 You now have an accurate scaled proportion of your piece of paper. Some students string cotton across the window to make a grid. Put the window up to the you see through the window on to your world and choose your composition. Now paper. Doodles are usually created with potential of their ideas in their sketchbooks.
They are usually a secondary They make thousands of rough sketches part of our thinking process. For example continually changing and rethinking their most of us doodle when we are in meetings ideas. Stretching the thinking and the - it helps us to escape the boredom of the dynamics of their designs to the limit.
We also doodle allows for client comment. Before honing in when we are on the telephone when we tend on a final statement, all this starts with visual to use the phone pad as a sketch book.
I thoughts translated through sketches. All believe there is a wealth of ideas that come those ideas, even the redundant ones are left from doodles so treat them as research.
Shape can have a very intuitive influence. Most artists always carry a sketchbook with Only as we become more experienced do we them. It allows us to record moments that become formally aware of how to construct a include landscapes, portraits, textures, composition.
Intuitively, the beginner will architecture, nature, light, atmosphere, and invariably place the mass of the subject still so on. This is all visual research that is life, portrait, whatever in the middle of the stimulation and a continuous resource for picture plane. In 90 cases out of this our ideas. Sketchbooks of artists are placement is a mistake, creating too much of fascinating to look at, as in the sketchbook a focal point and not allowing the eye to be you can see the origin of ideas, and taken on a journey across, and into, the rest responses, that the artist is engaged with.
What we intend MOVEMENT to do with shape in these projects is to give you basic experience in using hard pencils to The importance of movement through the create shapes that, when drawn on a picture picture plane cannot be over-emphasized.
The artist can engage Sometimes this movement across and the eye of the viewer so that it moves across through the plane happens intuitively, but the picture plane, stop the eye at a certain more often than not it is confirmed when point and then move it back into space, you see an artist working and they step back bring the eye forward again, and at the same from the picture and gesture towards their time across the picture space, and then take piece of work with arm outstretched, head the eye right out of the picture to the end of tilted sideways and hand or thumb looking its journey.
Most viewers are unaware of this as though they are engaging with the picture visual encounter, which tends to occur in some way. This is when the artist is trying within a few seconds of looking at a picture. There are, of course, many ways other Rhythm is very obvious in other forms of than the use of movement by which artists art, such as music, dance and writing.
It is a can - either consciously or subconsciously - sort of beat holding the work together. In a enable us to read and understand their work. Rhythm can be created, especially if we want to achieve an evident in the use of tone, colour, mark and expressive effect. The artist In any given picture there are a series of does this by drawing the space around tensions that must play off and counter each objects rather than by trying to capture the other so what we finish up with is a pictorial shapes of individual objects in isolation.
This is what is meant by a composition having a semblance of order and balance. If you look at most classical works of art, particularly landscapes by Poussin or Claude, you will see this quality in abundance. We can see the picture plane and our sense of the there is order and balance and that our eye decreasing scale of the shape perspective.
There is no rhythm suggestive of the ticking of the ambiguity interrupting the flow. Movement second hand of a clock. What we shall show you is how that line travel over and into the surface of the can be employed to demonstrate your ideas, picture, and how we read the picture in a expressions and observations. Finally, we explain First, we must complete a series of the nature of diagrammatic and perspective exercises to see and experience what we can drawings both from theoretical and achieve with the material.
In many ways observational approaches. We will show you these exercises are like the warm up routines how to develop these methods for use in that sportsmen and women go through your particular approach to drawing and to before they take part in an actual event - by expand upon them whenever you feel it is loosening us up they enable us to focus on appropriate.
The next stage involves experimenting Medium: 6H, 5H and 4H with the concept of shape, space and As you will see, the types of marks or lines composition over the picture plane. I personally would not use tonally than was achievable with the them to build up tone, because the contrast previous set of pencils. You can still make you can produce with them is limited. There clearly develop the weight of the mark, and are no hard and fast rules in art, and if it bring more expression and life to what you suits your purposes to work tonally with are doing.
These are ideal implements for pencils in this range, then by all means do putting down your first thoughts and making so. Next we are going to draw shapes - shapes The definition of shape is that it has that will imply meaning in a non-repre- perimeter and lies flat upon the picture sentational way and will create tension on plane unless we relate it to other shapes the surface of the paper.
The shape contains which can then imply space. It is a very useful the essence of any composition - a exercise to practise drawing shapes — combination of harmony, balance, rhythm, squares, circles, triangles, rectangles and any movement and spatial implications. These type of organic shape.
It is also useful to are the basic components that hold a practise turning shapes into illusions of drawing together and the dynamics that a form; for example, making a circle into a composition needs to express an idea.
The sphere, a triangle into a cone, an oblong into interrelationships between them are key to a cylinder. These exercises are essential for the making of a successful drawing. In the the beginner. The basic shapes you will encounter in most drawing compositions. Without a sense of triangle a cone, and the oblong a cylinder.
Spheres Cross-sectional analysis. Cube: parallel lines. Form of oblong: parallel and perspective lines. Pyramid shading using vertical lines. Cone: diagonal line shading. In this example, after to pull the eye upwards to the top edge of the Malevich, shape is used to bring a sense of picture plane.
This triangle is the base on order, balance, rhythm, harmony, movement which the rest of the picture hangs and the and space to the picture plane. We see the device that holds it together. All activity in the bones of the composition that any great picture revolves around this basic structure picture has as its structure.
Playing with composition: Line creates a Shape overlapping shape. Tone emphasises space. The of the picture plane we are seized by a sense of composition is based on the organic flow of falling and despair. Note also a sense of space shapes. There is more fantasy, almost a dream- that gives the illusion of movement through like quality. The organic shapes and the sense the picture plane.
This is created by scale and of texture suggest that the picture is growing weight of mark. The space is constructed by and expanding before our eyes. Line creates organic shape. Shape overlapping shape creates space. Shapes creating a transparent overlap. Textured overlapping shapes creating space. It is now important With the Malevich and Miro copies, we have to try to assess how far that line goes into the been looking at examples of positive paper before it encounters the vase that holds composition, drawing shapes of objects we the flowers.
Do this by looking through your have in mind and placing them to create an window mount again, remembering to look effect. A different way of understanding shape through it in exactly the same position every is to draw the space around the positive.
This time. The window mount should be is called the negative space, and is a very proportionally marked as showing halves effective way of creating relationships quarters, and eighths as seen in the example between objects in a drawing. One can now begin to make an When analysing the drawing of sunflowers assessment as to how far that line travels into after Van Gogh I can see quite clearly how the picture by using these proportions.
The negative shape, or the way in. We would then translate that shape around the flowers in this composition observation from our window mount to our is just as important as the flowers or the drawing allowing the line that we first started positive shape, and it is integral in holding the with to travel into the drawing a quarter of the composition together.
The negative shape way, where it would then engage with the underpins the composition and helps the vase. Now the line would start its journey sense of harmony, balance, proportion, and around the vase being monitored for rhythm that gives the picture its wholeness. Eventually the line will complete its subject in its environment or context. Then set up as if to draw, example 1. Now In example 2 you will restart the drawing take a viewfinder or what we know as a in exactly the same place over the top of your window mount and frame the composition of first line.
However, when it engages the vase the flowers. We are going to copy the this time the line will detour around the composition in the window mount and place bottom edge of the vase, and it will progress it on our paper, by mapping the composition following the outline of the vase until it using the negative space.
This part of the drawing should be easier to accomplish HOW TO START as the first part of the drawing will help you in your understanding of the second part of the In the first example you will see that what we drawing and so on. The drawing as in example have drawn what appears to be a silhouette 2 will now contain three sections to it rather over the top of the flowers.
Do this by starting like a simple jigsaw construction. Start to silhouette, and finally the overall shape of the progress the line towards the centre of the objects that are contained in the composition paper following what would be the line that i. This part of references. Now we have a complete work the drawing completes the drawing of the that pulls on a number of visual elements to negative space, and at this point we can now make it work. There is also an example in the see how important this concept is as it holds charcoal section that illustrates how a the whole composition together in a spatial negative space drawing can be constructed.
In other words the objects appear to be anchored in a real space, rather than floating in the picture plane 3. Not only form by the use of shading. We can see in the has he given them form, he has given them a drawing after Picasso opposite, below that character, and a life. He has created the form regular shapes have been given the illusion by using different types of bracelet, of three dimensions by using various well- crosshatch, and linear lines to build up tone.
He has taken All these processes are consistent in that these shapes and turned them into they follow the planes of the form You will see from the examples that some systems of shading suit different types of forms. An example of shape using tone after Morandi. Sphere using crosshatch shading. Diagonal line shading. Below: After Picasso. Note that although different methods have been used, all follow the plane or surface of the form. This drawing seems to have composition is based on a more organic flow a life, and we have a sense that it is still of shapes.
Part of its impact is created by the growing. All the elements we like quality. Try success of the following portrait, which I to do this with a free, expansive movement, built up in a series of six drawings.
I used a sensing the shape rather than using your eye 2B pencil and cartridge paper, but almost to gauge it precisely.
Repeat the shape several any pencil would do, as would any type of times, drawing over your original lines, as I paper. You might like to practise drawing have done here. Now draw an ellipse, as ellipses, cylinders, eggs or ovoids before shown, to give the shape the appearance of starting. Now extend the ellipse to meet these lines, giving the form of the skull. The lines of the ellipse are called cross-sectional analysis lines. They enable you to have a full visual understanding of the form and a sense of the back, front and sides of the head you are creating.
These lines also provide the illusion of volume. Draw two parallel lines at a slight angle from the centre plane of the forehead. This appears as a wedge protruding out of the front plane of 2. At the bottom to give a sense of form to the front of bottom of these two parallel lines, draw a line the face. Join these two lines at the bottom between them and which then extends back with a straight line that follows the angle of in space following the front plane or angle of the front plane of the face and then follows the face.
Now draw a line tilting back in space the angle of the side of the head through to and following the side plane or angle of the the back of the original egg. If you look at the head. From lines used to establish the nose, only on a both corners of the front plane of the bigger scale. We now have the underlying forehead draw two downward lines to just form of the chin and jawbone.
One sphere lies in front of the nose, the other directly behind it. Now we have the underlying volume of the eyes. Once this is established it is your base over which you can draw in the characteristics of the particular person who is sitting for you. There based on observations direct from a figure. The Picasso copy has Crosshatching alone has been used to build up tone in this drawing. We get an illusion of volume from this because we sense only one light source is falling upon the figure.
A build up of crosshatching techniques. Using crosshatching to build form. The Medium: 3B light cast at this angle is very intense, gradually The tone used here relies on an observed fading to complete darkness towards the sides directional light source, which is then of the cone.
Lighting was used by early exaggerated to create the effect. The shadow Renaissance artists such as Giotto. Without it the drawing would look flat. Medium: 6B The cylinder is like the sphere in observation, Medium: 4B tone and how light plays across the surface of This cube has been constructed using three the form. But the tone we have used to define defined tonal variations - white, grey and black the form is an expressive gestural tone.
It has — to give the illusion of form. It is a constructed less form than the previous tonal gradation illusion, of course, and has not come about as and is more emotive and responsive to the a result of observed tonal changes. This is technically referred to as the first angle Theoretical drawing systems include projection. First introduced by a French orthographic drawings, planometric drawings, military engineer, Monge, at the beginning of isometric or parallel drawing systems, the 18th century, it was very quickly adopted.
Orthographic drawings represent the These drawing systems are very useful object being drawn, or the face of, and from particularly for architects and designers. They that face the other faces can be planned and are usually used as presentation drawings for plotted. The orthographic or the planometric system of drawing is probably the easiest to understand as this is just a flat representation of an object, usually from the front and is done to a scale.
See the example on page 55 of a pair Front elevation of scissors, and pliers. Sometimes in these drawings, you will have tonal keys to give you the idea of plane recession, and form. The easiest way to go about producing one of these drawings is to place an object like a pair of scissors down on to a piece of paper and then draw around them.
What you will have produced in this drawing is an outline of the object and that is what an orthographic Front Side projection is. To complete the drawing, observe, and draw in the rest of the detail of the object and then code it tonally or texturally accordingly.
They can A table, showing front, side and plan represent the design as linked individual elevations. This is usually referred to as plan, front and side elevations. The shape of an object from the front can be They can best be described as representing understood by placing it in a box or a silhouette of an object on the picture plane rectangle that relates to its proportions.
Parallel diagonal lines pick up the front plane. Flat tone is used to describe a flat plane down the edge of the pliers. First came the isometric projection from those two angles create two thirty process, introduced by an English con- degree angles that will converge and meet temporary of Monge, Sir William Farish, creating the top of the rectangle. For instance, an isometric One can also now use this rectangle or crate projection is always conceived by using an to plot an object within this projection angle of 30 degrees as shown in the system.
You can see in this example we have created a chair by creating it in an Isometric projection. There is also a simple example of an isometric projection shown on the right. In this example, you can see how a block has been cut had a segment removed. One can quite clearly see that all the angles for this drawing are based on 30 degrees of a 90 degrees angle.
Drawings based on this system were used in the aircraft industry to assemble aircraft, and they are used by interior and theatre designers as finished working drawings that the makers would work from. The difference being that the trimetric projection can present different orientations of a box or object on the same picture plane. Therefore, what we have are different degrees of orientation. This type of drawing is very useful as a diagrammatic drawing that is used to help you assemble or even take apart a piece of furniture or machinery.
One usually sees these types of drawings in car manuals. By encasing volume and form in this way, designers can visualise how their ideas will appear in reality. For example, a representation from one view point. Perspective is a system of constructed on a picture plane has an drawing that shows the illusion of three- established ground and horizon upon which dimensional objects in a picture space.
To objects can be placed in relation to it. To break these systems we have been looking at in that it rules is to undo the illusion. These two systems employ the same other is constructed from an understanding of rules, although they arise from different planal recession and form.
It is appertain to the horizontal or the vertical axis important that extreme accuracy be observed will go back to or terminate at the perspectival in drawings of this type, as any slight mistakes point that as been set up in this drawing. Make sure that this square runs of the far end of the square. You will now have parallel to the edges of the paper. Do this by drawing in a vertical drawings from observation it can be referred between the set of converging lines that we to as your eye level.
Place the line too far away and you other side of the paper to the square you have produce an oblong lying down, and place the just drawn. This is now known as the vanishing line to close and you produce an oblong point. So try to place the line so it makes the illusion of a cube. Other examples of one-point perspective.
The difference dynamics of perspective space. We instead draw a vertical line just and the bottom of the vertical to the to the left or right of centre. Do this by placing a paper to the other. For other practice vertical line on one side of the original examples, you can be diverse as to where vertical so as it fits between the converging 1.
Then repeat the process on the need to do is to draw a vertical line between other side of the original vertical. You will the two points at which they cross at the now have created a box in a twisted back of the box. This process described here right-hand side this is shown as a dotted line has also been used in the observed in the example. Draw two lines from the top and bottom of this vertical that will extend back to the vanishing point on the left hand side.
To start the drawing first establish your establish our eye level in the drawing. To do composition through your window mount. We can establish the first major vertical in the do this as we did for the posture lines, holding composition.
From this we can establish the the pencil on the angle of the building and horizon line or your eye level. It is important then transporting this angle to both the top that you keep this view constant while you are and bottom of the vertical line.
If you find this engaged in the drawing, otherwise you will process particularly difficult, you can use a experience distortion. Establish it first, as you will be making your major perspectival assessments from it. In the first example you can see that the corner of the building in the row of houses is our main point of departure.
So draw the vertical in position accurately first. In our drawing, we have now established where the corner of the house is and its height. As fit exactly between the two converging lines to with the example of the isometric drawing, I give us the correct perspective. You can place a right angle to the using the same process. However, you will vertical and then make an approximation as to notice that the perspective point on this the angle of your observation. When you feel occasion goes off the other side of the picture.
In this detail we have them to the point where they converge. At this extended the drawing perspectivally forward point you will have established for that to draw the row of houses in the foreground. This has been achieved by extending the It is on this point also that the horizon line, or perspective lines that come from the the eye level, is established.
Now you can draw vanishing point on the horizon line, and then in the eye level line by simply making a placing the vertical line in to denote the edge horizontal line across your paper. There is a of the building. At this stage your vanishing point. The accuracy of these drawing will lack expression or character. In measured angles is vital to the success of the this final stage we need to put in the elements drawing.
Once you have the two converging that make the drawing more real, such as the lines from your first vertical, you can use them van, the telegraph poles, the curving side of as guides to draw the rest of the building. Finally, it all needs to be brought building is by looking back at the composition to life by working over the top of the through the window mount.
Put in a vertical perspective with free, gestural lines. One can construct drawings that will lead the eye through a well-organised perspective or architectural space both for interiors or exteriors. In our example the light is coming from a fixed position on the left side. Once the 1. The figure here form of the portrait. The first concerns of this drawing are to 2. You will notice there is a very strong direct The light becomes more distinct on how it light that plays over the surface of the subject.
Draw two lines for the neck, and then two arced lines for the shoulders. This will give you the basic outline for the form of the head. You can now initially place the basic areas of shadow in on one side of the head leaving the other side in the light.
But you need to put some shadow on the outside of the head so as to pick up the 3. Notice the free sketched way in which the tone has been placed down at this point in the More tonal detail that brings out the drawing. It certain touches of light, just to enhance the is a mistake in this type of drawing to try and atmospheric effect of the light.
Revision data. Protractor—used to measure the angles between lines. Scales—used to measure distances on drawings. Like rulers, scales provide graduated marks that are used to determine the length of objects, as shown in Figure Download This section contains free e-books and guides on Engineering Drawing, which can be viewed online or downloadable in pdf, chm, rar or zip.
Engineering Symbology, Prints and Drawing Volume 1 of 2 Engineering Symbology, Prints and Drawing Volume 2 of 2 Fashion drawing is an excellent method of developing and realising your design ideas. It allows you to visually play with design lines and features without the need to make costly samples. Good quality technical drawings are imperative for the industry, yet many people struggle with their drawing abilities and often lack confidence in their skills.
