## What are the standard views for orthographic projections?

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 standard views in an orthographic 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.

## Is orthographic projection two-dimensional or three-dimensional?

The orthographic projection is derived from the principles of descriptive geometry and is a two-dimensional representation of a three-dimensional object. It is a parallel projection (the lines of projection are parallel both in reality and in the projection plane).

## How many dimensions are there in an orthographic projection?

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 used in constructing isometric drawing?

There are two common techniques generally used for isometric drawings. These are the box and the centerline layout techniques, but the box technique is the most common construction technique. The box technique is also known as the coordinate technique.

## What is Third 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.

## Why 2nd and 3rd angle projections are not used?

As per rule of projection when the horizontal plane is rotated 90 degree in clockwise direction, top and front view will overlap. To sum up, Because of overlapping of front and top views 2nd and 4th angle projections are not used. First and third angle projection systems are recommended for orthographic projections.
