Difference between Isometric, Oblique and Orthographic Drawing

Isometric means "equal measurement". The true dimension of the object is used to construct the drawing. You get the true dimension from either orthographic views or by measuring the object. Because of the convenience of using actual measurements to create the isometric image, it has become the industry standard for parts manuals, technical proposals, patent illustrations and maintainance publications.

The height of the object is measured along vertical lines. The width and depth of the object are measured along the 30 degree to the horizontal plane.

Oblique drawing is the crudest '3D' drawing method but the easiest to master. Oblique is not really a '3D' system but a 2 dimensional view of an object with 'forced depth'.

When using oblique the side of the object you are looking at is drawn in two dimensions, i.e. flat. The other sides are drawn in at 45 degrees but instead of drawing the sides full size they are only drawn with half the depth creating 'forced depth' adding an element of realism to the object.

Even with this 'forced depth', oblique drawings look very unconvincing to the eye. For this reason oblique is rarely used by professional designer and engineers.

Orthographic Projection is a way of drawing an 3D object from different directions. Usually a front, side and plan view are drawn so that a person looking at the drawing can see all the important sides. Orthographic drawings are useful especially when a design has been developed to a stage whereby it is almost ready to manufacture.

Definition of Theme - Environment

Environment is everything in our surroundings, including plants, animals, buildings and people. It is the totality of circumstances surrounding an organism or a group of organisms, especially the combination of external physical conditions that affect and influence the growth, development, and survival of organisms and the complex of social and cultural conditions affecting the nature of an individual or community.
(adapted from:

It is the aggregate of social and cultural conditions that affect nature and the factors which affect the survival and form of organisms and objects. It is the position or characteristic position of a linguistic element in a sequence.
(adapted from

Environment is the external conditions, resources, stimuli etc. with which an organism interacts. It includes all of the biotic and abiotic factors that surround and affect the survival and development of an organism or population. The environments maybe regarded as natural environment or built environment. They may also be marine, atmospheric, or terrestrial according to their attributes.
BIOTIC: of, relating to, or resulting from living things, esp. in their ecological relations
ABIOTIC:physical rather than biological; not derived from living organisms.
(adapted from

In short, environment is our surroundings, affects us and others, and is affected by us.

ADMT Lesson 1 : Personal Reflection

Art is the way of expressing oneself to the world using beauty. There are many forms of art, for example, paintings, sketches, collages, music, or even putting on make-up. It is arranging certain elements to make something appeal to someone else and stir feelings and emotions on the person appreciating it.

Design is planning for a piece of art. It may not be the physical piece, but it is what every piece of art begins with. It can be blueprints for a new building or a toy, or it can be how someone imagines a piece of art to be before he or she starts to make it. In short, it is a plan for the artwork.

Media is a form of communicating with people surrounding us. It tells people what type of person we are when we display something.

Technology deals with human as well as other animal species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its natural environment. The word technology comes from the Greek technología, the study of something, or the branch of knowledge of a discipline. A strict definition is elusive; technology can be material objects of use to humanity, such as machines, but can also encompass broader themes, including systems, methods of organization, and techniques. The term can either be applied generally or to specific areas: examples include "construction technology", "medical technology", or "state-of-the-art technology".

Art, design, media and technology means to combine all four to create something new, a form of art made with a meticulous design, created using technology.
