Question: What Is Orthographic View In Engineering Drawing?

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 6 orthographic views?

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 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 3rd Angle Projection?

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.

How do I choose a front view?

Select the BEST FRONT VIEWDoes it show the contour of the part?Does it look stable?Does the part appear in its natural position?Does the view include the longest overall dimension of the part?Does the view have few hidden lines…. and result in few hidden lines in the other views?

What is the meaning of orthographic drawing?

An orthographic drawing represents a three-dimensional object using several two-dimensional views of the object. It is also known as an orthographic projection. For example, you can see in this image the front, top and side views of an aircraft.

What is an orthographic view in Autocad?

Orthographic drawings display two-dimensional views of piping, valves, equipment, and structural steel in Plant 3D models. The drawings can have annotations, dimensions, matchlines (plan view only), pipe gaps, and can show or hide lines and objects. Here is an example showing a single view.

What is front view?

A front view is a projection view obtained by drawing perpendiculars from all points on the edges of the part to the plane of projection. The plane of projection upon which the front view is projected is called the frontal plane.

What is the purpose of an orthographic view?

orthographic views: A way to draw an object that shows three views of an object from the three planes in an orthogonal (right angle) coordinate system. The views represent the exact shape of an object as seen from one side at a time as you are looking perpendicularly to it.

What are the two main types of projection?

The most common types are the perspective and orthographic projections.

What are the advantages of orthographic drawing?

Orthographic Projection: The advantages of using orthographic are: They can show hidden detail and all connecting parts. They can show all dimensions necessary for manufacture. They can be annotated to display material and finishes.

What is difference between orthographic and isometric view?

Isometric: a method of representing three-dimensional objects on a flat surface by means of a drawing that shows three planes of the object. Orthographic: a method for representing a three-dimensional object by means of several views from various planes.

What are the 3 principal views?

For this object three views are created: front, top, and right side. The views are aligned so that common dimensions are shared between views.

What is 1st angle and 3rd angle?

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 is 1st angle projection?

First angle projection is a method of creating a 2D drawing of a 3D object. It is mainly used in Europe and Asia and has not been officially used in Australia for many years. In Australia, third angle projection is the preferred method of orthographic projection. Note the symbol for first angle orthographic projection.

What angle is used in orthographic projection?

90 degreesSummary. Orthographic projection uses multiple views of an object, from points of view rotated about the objects centre through increments of 90 degrees. In first angle projection, each view of the object is projected in the direction (sense) of sight of the object.
