How Do You Draw Orthographic Drawings?
What is orthographic drawing? An orthographic projection is a way of representing a 3D object by using several 2D views of the object. Orthographic drawings are also known as multiviews. The most commonly used views are top, front, and right side.
How does orthographic drawing work? Orthographic projections are working drawings in either a first or third angle projection and show each side of a design without perspective , ie a 2D drawing of a 3D object. They are used to show an object from every angle to help manufacturers plan production. These drawings are to scale and must show dimensions .
What angle is orthogonal drawing? Orthographic projection is a means of representing a three-dimensional object in two dimensions. It uses multiple views of an object, from points of view rotated about the objects centre through increments of 90 degrees.

Who uses orthographic drawing?
An orthographic drawing is a clear, detailed way to represent the image of an object. It may be used by engineers, designers, architects, and technical artists to help a manufacturer understand the specifics of a product that needs to be created.
What is the purpose of orthographic drawing?
Orthographic projection are detailed line drawings which convey technical and dimensional information. The drawings normally show the product in front, end and plan view. The advantages of using orthographic are: They can show hidden detail and all connecting parts.
What is an example of orthography?
The definition of orthography is the practice of proper spelling, a way of spelling or a study of spelling. An example of orthography is spelling definitely as “d-e-f-i-n-i-t-e-l-y.” The art or study of correct spelling according to established usage.
What is the most important orthographic view of a drawing?
How many views do you need for an orthographic drawing or projection? As I said, in most cases 3 views are enough and are the most important ones to have. The front, side and plan view.
What is another name for orthographic drawing?
a two-dimensional graphic representation of an object in which the projecting lines are at right angles to the plane of the projection. Also called orthogonal projection .
What are the two Greek words of orthographic drawing?
Orthographic comes from the Greek roots ortho, meaning correct, and graphos, meaning writing. You have made several orthographic errors if you write “alot of peeple came two the skool.” The spelling of “a lot,” “people,” “to,” and “school” are all incorrect.
What are sketches or technical drawings called?
Technical drawing, also known as drafting or draughting, is the act and discipline of making detailed drawings. These drawings visually communicate how something works or how it is to be made.
What are the 3 views commonly placed in a working drawing?
Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. These views are known as front view, top view and end view. Other names for these views include plan, elevation and section.
What method did we use in sketching orthographic drawing?
Orthographic projection, common method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing.
What are the three ways in presenting orthographic 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.
What is the most used Paraline style?
Axonometric drawings can take on one of several forms, the most common being isometric, diametric, and trimetric. Figure 4.13 illustrates the different types of paraline drawings.
What is the 3rd angle?
3rd Angle project is where the 3D object is seen to be in the 3rd quadrant. It is positioned below and behind the viewing planes, the planes are transparent, and each view is pulled onto the plane closest to it. The front plane of projection is seen to be between the observer and the object.
What is 1st angle projection?
In the first angle projection, the object is placed in the 1st quadrant. The object is positioned at the front of a vertical plane and top of the horizontal plane. First angle projection is widely used in India and European countries. The object is placed between the observer and projection planes.
What is the difference between 1st and 3rd angle drawing?
In third-angle projection, the view of a component is drawn next to where the view was taken. In first-angle projection, the view is drawn on the other end of the component, at the opposite end from where the view was taken.
What is 1st and 3rd angle projection?
To get the first angle projection, the object is placed in the first quadrant meaning it’s placed between the plane of projection and the observer. For the third angle projection, the object is placed below and behind the viewing planes meaning the plane of projection is between the observer and the object.
What are perspective drawings?
Perspective drawing is a technique to create the linear illusion of depth. As objects get further away from the viewer they appear to decrease in size at a constant rate. The box in the sketch below appears solid and three dimensional due to the use of perspective.
What is the working drawing?
A working drawing is a drawing or blueprint based on explanations. Conventionally, working drawings consist of two-dimensional orthogonal projections of the building including sections, plans, and elevations. These are either drawn by hand or using a Computer Aided Design (CAD) software.
