Quick Answer: What Are The Principles Of Orthographic Drawing?

How do you start an orthographic drawing?

Creating an Orthographic ProjectionChoose a front view.

Decide how many views are needed to completely describe the object.

Draw the visible features of the front view.Draw projectors off of the front view horizontally and vertically in order to create the boundaries for the top and right side views.Draw the top view.More items….

What are the 3 main views of an 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 purpose of 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 meant by 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 is Section AA in drawing?

A section view is a view used on a drawing to show an area or hidden part of an object by cutting away or removing some of that object. The cut line is called a “cutting plane”, and can be done in several ways.

What drawing means?

The Shorter Oxford Dictionary defines drawing as: ‘the formation of a line by drawing some tracing instrument from point to point of a surface; representation by lines; delineation as distinguished from painting…the arrangement of lines which determine form. ‘

What does orthographic mean?

orthography \or-THAH-gruh-fee\ noun. 1 a : the art of writing words with the proper letters according to standard usage. b : the representation of the sounds of a language by written or printed symbols.

What are the 3 planes of projection?

[FIGURE 3-2] Projections of the point are made onto three of the surfaces that make up the box: the top or “H” (horizontal) plane, the front or “F” (frontal) plane, and the right side or “P” (profile) plane.

What is the most important view in an orthographic drawing?

The 3 main views used in orthographic projection/drawing are the Front, Side, and Plan (Top) view. With only these 3 views, you can already have a very clear idea of how the object looks, and you can detail it quite well if you try to build a 3D version of it.

What are the six views of an object?

In orthographic projection there are six possible views of an object, because all objects have six sides – front, top, bottom, rear, right side, and left side.

What is the most important rule in freehand sketching?

The most important rule in freehand sketching is to keep the sketch in proportion, which means to accurately represent the size and position of each part in relation to the whole.

What are the principles of orthographic projection?

Orthographic Projection is a method of producing dimensioned working drawings or blueprints of 3-D Objects using a series of related 2-D views of the object to communicate the object’s length, width and depth.

What are the 6 principal views of orthographic drawing?

views that are produced by six mutually perpendicular planes of projection. surfaces of the object positioned so that they are parallel to the sides of the box, six sides of the box become projection planes, showing the six views – front, top, left, right, bottom and rear.

What are the two types of orthographic projections?

First angle projections and third angle projections are the two main types of orthographic drawing, also referred to as ‘working drawings’. The difference between first and third angle projection is in the position of the plan, front and side views.

What are the types of projection?

Projection Methods Used In Mechanical DrawingOrthographic Projection. Orthographic projection shows a 3D object in two dimensions so that you can see three views: the front view, side view and top view. … Axonometric Projection. Axonometric is another type of orthographic projection. … Oblique Projection. … Perspective Projection.
