How many types of views are there in projection drawing?
Typically, an orthographic projection drawing consists of three different views: a front view, a top view, and a side view. Occasionally, more views are used for clarity. The side view is usually the right side, but if the left side is used, it is noted in the drawing. One may also ask, how many types are there in drawing?

What is an engineering drawing?
However, the terms are becoming an anachronism since most copies of engineering drawings that were made using a chemical-printing process that yielded graphics on blue-coloured paper or of blue-lines on have been superseded by more modern reproduction processes that yield black or multicolour lines on the white paper. The more generic term “Print” is in common usage in the U.S. to mean any paper copy of the engineering drawing.
What is technical drawing?
The process of producing engineering drawing , and the skill of producing , is often refered to as technical drawing , although technical drawings are also required for disciplines that would not ordinarily be thought as parts of engineering.
What is orthographic projection?
Orthographic projection is a way of representing a 3-dimensional object in two dimensions. It is a form of parallel projection , here the view direction is orthogonal to the projection plane, resulting in each plane of the scene appearing in affine transformation on viewing surface. It is further divided into Multiview Orthographic projections and Axonometric projection.
What is an auxiliary view?
The auxiliary view is an orthographic view that is projected into any plane other than one of the 6 principal views. The views are used when an object contains some sort of the inclined plane. Using the auxiliary view allows for inclined plane to be projected in true size and shape. The true size and shape of any feature in a technical drawings can only be known when the Line of Sight is perpendicular to the plane which is considered as reference.
What is oblique projection?

What is engineering drawing?
An engineering drawing is a subcategory of technical drawings. The purpose is to convey all the information necessary for manufacturing a product or a part. Engineering drawings use standardised language and symbols. This makes understanding the drawings simple with little to no personal interpretation possibilities.

The different options make it possible to show both visible and hidden edges of a part, centre lines, etc. The most common is a continuous line, also known as a drawing line . This represents the physical boundaries of an object.
What is orthographic view?
This is the bread and butter of an engineering drawing. An orthographic view or orthographic projection is a way of representing a 3D object in 2 dimensions.

What is Engineering Drawing?
An engineering drawing (also named as mechanical drawing, manufacturing blueprints, drawings, dimensional prints, and more) refers to one of the technical drawings, which helps to define engineering products’ requirements. Basically, this type of drawing aims at clearly capturing all the geometric features of products and their components. This will ensure that manufacturers can produce parts that meet specific needs.
What is the most common type of line in engineering drawings?
There are various options available, making it possible to show hidden and visible edges of parts. The most common type of line is the continuous line . Many people refer to this as a drawing line. It represents an object’s physical boundaries.
What is isometric drawing?
Isometric drawings show a three-dimensional view of parts. Vertical lines remain vertical, and parallel lines come at a 30-degree angle. The lines in this type of view are in their true length. With this type of view, engineers stay true to the dimensions instead of using optical illusions.
What is a drawing line?
Many people refer to this as a drawing line. It represents an object’s physical boundaries. That is, it is a type of line used for drawing the object. The thickness of the line varies. Outer contours use thicker lines, with inner contours use thinner ones.
What is included in a mechanical drawing?
As already mentions, this mechanical drawing includes every piece of information needed for manufacturing components. The information may include dimensions, part numbers and names, variations, tolerances , and more. Therefore, an engineer can start the manufacturing process immediately after he gets the drawing.
Why is orthographic projection important?
This is one of the most preferred views in an engineering drawing. An orthographic projection helps to represent a 3D object in 2D. This ensures the conveying of everything needed for the production of components. Also, there is no distortion of the length of any kind.
Do you need assembly instruction in engineering drawings?
If the production involves the machining of an entire assembly, you should include an assembly instruction in your engineering drawing. Also, you can provide part numbers for your machinists to look up. This is especially important if you’re installing off-the-shelf hardware yourself.

How to Make Drawings?
- A few decades ago, you would have had to sit down at a drawing board covered with papers of different size, rulers, callipers, etc. Today, all these instruments are still good for manual drafting but no contemporary manufacturer really wants such drawings. Why? Because most of the machinery uses CNC systems that can read the information straight from the files and produce …
Basic Components of An Engineering Drawing
- Let’s see what makes up an engineering drawing. A single drawing includes many elements with quite a few variations to each of them. So let’s take a closer look here.
Assembly Drawings
- Many engineers’ drawings make the mistake of trying to include all the information about each individual part in an assembly drawing. To avoid this, remember the purpose of these engineering drawings during the creation process – they must make the assembling easy. Exploded views, section views, numbered parts, general dimensions, cutouts, detail v...
What Does The Future Hold?
- Engineering drawings are still a big part of an engineer’s job. All in all, making them contributes to about 20% of a design engineer’s work time. We at Fractory are trying to save this time by automating the reading of 3D models for production. This leaves engineers with the task of producing assembly and GD&T drawings only. The purpose is to keep the focus on engineering …
