Difference between Isometric, Oblique and Orthographic Drawing

An Isometric drawing is a method of visually representing three-dimensional objects in two dimensions, in which the three coordinate axes appear equally foreshortened and the angles between any two of them are 120 degrees. It is used in technical and engineering drawings.

An Oblique drawing is a simple type of graphical projection used for producing pictorial, two-dimensional images of three-dimensional objects.

An Orthographic drawing is a means of representing a three-dimensional object in two dimensions. It is a form of parallel projection, where the view direction is orthogonal to the projection plane, resulting in every plane of the scene appearing in affine transformation on the viewing surface.

Definition of the theme- Environment

The environment is the circumstances, objects or conditions surrounding a person. The environment can influence a person or affect a person’s growth, so choosing an appropriate environment is essential.  For instance, the example of 孟母三迁. 孟子 was affected by the environment he lived in; when he stayed near a market, he begun to talk like a businessman and had many ideas of making money. When he moved near a cemetery, he began to imitate the cries of the family members of the lost loved one. Finally, when he moved near a school, he started to like studying. From this example, we can see how the environment can greatly affect a person’s life.

Another definition is specifically related to design and technology, such as architecture, landscaping, interior setting/design which deals with manipulation and function of space.

ADMT Lesson 1- Personal Reflection

  • 1. ADMT means using technology to communicate and interact with other people. 
  • 2. An ADMT student should have respect and responsibility. As most of the time we do research on the Internet, we ‘copy and paste’ their texts. We should state the source of where we got this information from. 
  • 3. To learn how to make use of technology to help other people 
  • 4. Example: installing a GPS system in the wheelchair so the elderly or disabled will not easily get lost. 
  • 5. See picture below.
