Keeping this in consideration, what are the 4 basic components of an engineering drawing? The main purpose of engineering drawings is to communicate to other engineers, machinists, etc.
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 are the appearances of views in drawing?
The appearances of views may be of as being projected onto planes that form a six-sided box around the object. Although six different sides can be drawn three sides of a drawing give enough information to make a three-dimensional object. All these views are known as front view, top view and right side view.

What are sectional and auxiliary views?
A view that is needed to show the true size and shape of an inclined surface and other features which cannot be seen in regular views. The line of sight is perpendicular to the incline surface or feature of interest. Auxiliary views are projected onto a picture plane that is at an _______ to any regular view.
How many orthographic views are there?
three orthographic viewsStandard practice calls for three orthographic views, a front, top, and side view, although more or fewer views may be used as needed.
How many views exist for an object?
In multiview drawings, generally three views of an object are drawn, and the features and dimensions in each view accurately represent those of the object.
What are primary views?
Primary View means a visual scene from a single fixed vantage point or location within the primary viewing location or area that is not significantly impaired by vegetation. Sample 1.
What is top view and front view?
Front view = Elevation (The views from the front and sides are called the elevations) Top view = Plan (The view from the top is called the plan)
What is a sectional view?
A sectional view represents the part of an object remaining after a portion is assumed to have been cut and removed. The exposed cut surface is then indicated by section lines. Hidden features behind the cutting plane are omitted, unless required for dimensioning or for definition of the part.
What are the 3 point perspectives?
Three point perspective is a form of linear perspective that utilizes three vanishing points in which forms utilize each of the 3 vanishing points to convey the illusion of depth on a two-dimensional surface.
What are the 3 principal views used in orthographic and isometric drawing?
Generally, three views of an object are prepared. These are Top View, Front View, and Side View. If the plane is kept in a vertical position, then it is called the vertical plane.
What are the three views of an isometric drawing called?
You may be wondering about the three views that are hidden. They are called the Bottom View, the Left Side View, and the Rear View. Can you determine where they go? The next drawing shows the relationship of isometric surfaces to the views in orthographic drawings.
What is 3 point perspective used for?
Three-point perspective is often used for buildings seen from above (or below). In addition to the two vanishing points from before, one for each wall, there is now one for how the vertical lines of the walls recede. For an object seen from above, this third vanishing point is below the ground.
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.
What are the different types of lines in engineering?
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 does the line thickness mean in drawing?
This represents the physical boundaries of an object. Put simply, these lines are for drawing the objects. The line thickness varies – the outer contour uses thicker lines and inner lines are thinner. Hidden lines can show something that would not be otherwise visible on the drawings.

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.

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 …
