Who uses orthographic projection?

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.

Why orthographic projections are important?

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 all dimensions necessary for manufacture.

What is 3rd Angle Projection?

Third angle projection is one of the methods of orthographic projection used in technical drawing and normally comprises the three views (perspectives): front, top and side. … When using third angle projection to compile a diagram of the three views, we first draw the most prevalent side of the object as the front view.

What are the types of orthographic projections?

There are four types of projection but out of that only first angle projection and third angle projections are used.First angle projection.Second angle projection.Third angle projection.Fourth angle projection.

What does a hidden line look like?

If an edge or surface is blocked from view by another feature, it is drawn using a hidden line. Figures 4-11 and 4-12 show objects that require hidden lines in their orthographic views. … The hidden portion of the line is drawn using a hidden-line pattern, and the visible portion of the line is drawn using a solid line.

How do you do orthographic views?

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 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 is another name for orthographic projection?

Orthographic projection (sometimes referred to as orthogonal projection, used to be called analemma) is a means of representing three-dimensional objects in two dimensions.

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 are the 3 planes of orthographic projection?

These include the Frontal Plane, Profile Plane, and Horizontal Plane: In addition to this, if a plane is placed at any other place, then it is called Auxiliary Plane. These are used to draw inclined surfaces of an object.
