Technical and Architectural Drawings
Technical drawing or drafting is a basic communication skill used by most technical fields. Technical drawing is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering.
Computer Aided Drafting and Design (CADD) is the use of computers to aid in the creation, modification, analysis, or optimization of designs. CADD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database of plans for manufacturing.
Technical Drawings
- Different types of drawings are used for different purposes. Multiview or Orthographic Projection drawings are typically used for manufacturing different objects. These drawings are usually fully dimensioned so an individual can cut or shape the object.
- Isometric and oblique projection drawings are used to give you a good sense of what the object should look like or how it should be assembled. If you buy furniture, parts, or models that need assembled, isometric and oblique projection drawings are typically what you see. You do not need dimensions, just assembly instructions. Isometric and obliques are not true, in the sense that they do not represent an object completely, because they do not take into consideration that objects become smaller as they get farther away. They are easier to draw than perspectives which take depth perception into consideration.
- Perspective drawings utilize vanishing points to give you a sense of depth. They are most typically used in architecture to represent pictorial views of a building or other structure. They are more time consuming to produce, but allow for more artistic expression.
- Development drawings are used whenever an object needs to be drawn on a flat material, then folded into a final shape. The HVAC industry is always looking for someone with these skills in order to produce unusual ductwork from sheet metal.
- Three-dimensional drawings are produced on CADD (computer-aided drafting and design) programs and continue to grow out of industrial needs. All the above described drawings that are flat, 2D drawings that can be done on the table or any 2D CADD program. Their limitation is that they cannot be easily converted into any other type of drawing. A true 3D drawing can be used to generate any of them quickly and easily. Another benefit of 3D drawing is that it can be easily used with CNC (computer numeric controlled) machines that can manufacture the parts. 3D drawings can also give you photographic quality renderings and animations. If you watch movies like Toy Story you would be surprised as to how much drafting and CADD was used to produce the movie. 3D computer games also utilize much of what is learned in drafting.
