Understanding the Various Kinds of Views in Mechanical DrawingsShare
Whether you are trying to set up a simple commercial building or complex manufacturing facility, the work begins on paper before you can proceed with the construction. This allows you to have a clear picture of whatever thing you want to set up, allowing you to make any corrections as you may deem necessary. Generally, the structure is drawn to scale using ratios to represent the actual measurements of what will be on the ground. The designers also different views to give you an idea of what your project and structures will look like from various angles. Here is a look at the various kinds of views used in mechanical drawings:
Section views are defined as types of views that use a particular cut line to depict a cross-sectional area of the source object. In short, this is the type of view that shows the internal features of a structure, which you wouldn't see easily from the outside if the structure had already been set up. They show obscured features that exist but have been predominantly "hidden" by other imposing features. For this reason, a broken or dotted line is used to show angles, lines and features in section views. A section view is also useful for identifying hollows.
Multiview projection falls under orthographic projection. Orthographic projection refers to the practice of using a two-dimensional view to represent an object that has been drawn in a three-dimensional view. In multi-view projection, two techniques are used to represent the structure depending on your needs or preferences. They are:
- Third-angle drawing-here, the designer draws the sides of the structure based on their exact location. When you look at the back side of an object and rotate it through ninety degrees to the right, what will be seen is the right side. It is therefore drawn to the right of the back side.
- First angle drawing-the designer represents the structure on paper depending on where they land after rotating them through an angle. For instance, take the front side and rotate it through ninety degrees to the left. The result will be represented or drawn to the left, front side of that object.
Patterns are a simple type of view. Designers use them to depict the shape and size of a flat element that will be manipulated into a three-dimensional view at a later stage. In some cases, they are referred to as developments.
