Standard views are common in engineering drawings and are one of two view types that serve as foundations for supporting views; the other is the General view. For finding standard view location on a design, there are two angle projection methods: first angle and third angle. These methods use the angles of the drawing axis to determine where to place standard views.
Place one standard view at each endpoint of each face of the polygon defined by the drawing axis. The center of the face should be the location of the view. If you want, you can also place two more views: one at each end of the longest side of the polygon. These six views will cover all possible viewing directions from any point within the drawing area.
A seventh view may be useful when referencing part numbers or other device identification codes used on the drawing. This view can be placed at an arbitrary location within the drawing area. It can even be located outside of the drawing if needed.
The last standard view should be called "Main View" and it must be placed at a convenient location such as the top left corner of the drawing. This view can reference points or areas outside of the drawing if needed.
An optional eighth view may be placed so that it too references something outside of the drawing. For example, it could show the name of a project under which the drawing falls.
Pictorial and orthographic views (or "projections") are the three most common forms of views (or "projections") used in drawings. Pictorial views are classified into three types:
A two-dimensional line drawing of an item from a certain angle. Front, rear, top, bottom, left side, right side, and isometric are the seven typical viewpoints. A view is the visual perception of an object or part of an object by any human eye.
In general, there are between one million and six billion views of artwork in existence. However, some artists produce so many variations on a theme that it is difficult to estimate how many unique works of art exist.
The amount of art seen by people around the world is estimated to be about one hundred billion pieces. That means that every person on Earth has seen about ten thousand pieces of art.
That's a lot! But it's also a very small percentage of all the art that has ever been created. There are likely more than a trillion stars in the universe. Only a few of those have been identified as possible sites for extraterrestrial life. Yet we know of only one planet with humans on it!
It seems that we live in a pretty special place. The odds of finding another planet like earth are very low. But the odds of finding another star system like ours is very high. Our galaxy alone contains hundreds of billions of such systems. Some scientists believe that there may be as many as 100 billion galaxies in the universe!
Auxiliary View Types:
How do you choose which views to include in a multi-view drawing? Different projection systems can be utilized to provide the necessary views to completely characterize the 3D object when producing multiview orthographic projections. The most common projections used for this purpose are: linear perspective, two-point perspective, and three-point perspective.
In general, it is best to start with a simple view that will get your idea across clearly and then add more complicated views as needed to show more detail. For example, a cartoonist might draw a scene from one angle then move away from it to give it more depth. When adding new views, try not to cover up previous drawings or information. It is also helpful to note what parts of the drawing need additional detail before moving on to other things.
It is important to remember that all views of a drawing must be done from the same point of reference for them to be accurate representations of the subject. If different points of reference are used, each view will show a different part of the object being viewed.
