A. Parallel and Orthographic.
Station-point and Perspective.
Parallel and Convergent.
Perspective and Parallel.

What are the 4 standard types of projections?

Projection Methods Used In Mechanical Drawing

Orthographic 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. …
Oblique Projection. …
Perspective Projection.

How many types of projections are available?

Three of these common types of map projections are cylindrical, conic, and azimuthal.

What are the 3 planes of projection?

Figure 5-4 shows the three principal (or primary) planes of projection, known as the VERTICAL, HORIZONTAL, and PROFILE PLANES. The angles formed between the horizontal and the vertical planes are called the FIRST, SECOND, THIRD, and FOURTH ANGLES, as indicated in the figure.

What are the 2 types of projection?

Projection are defined as mapping of three-dimensional points to a two-dimensional plane. There are two type of projection parallel and perspective.

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.

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 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 6 types of map projections?

Introduction

Projection	Type	Key virtues
Stereographic	azimuthal	conformal
Lambert Conformal Conic	conic	conformal
Mercator	cylindrical	conformal and true direction
Robinson	pseudo-cylindrical	all attributes are distorted to create a ‘more pleasant’ appearance

What are the 3 types of map projections?

Conceptually, there are three types of surfaces that a map can be projected onto: a cylinder, a cone, and a plane. Each of these surfaces can be laid flat without distortion. Projections based on each surface can be used for mapping particular parts of the world.

What is projection explain the type of projection?

It is the process of converting a 3D object into a 2D object. It is also defined as mapping or transformation of the object in projection plane or view plane. The view plane is displayed surface. Next TopicPerspective Projection.

What are the 3 views of isometric drawing?

You may be wondering about the three views that are hidden. They are called the Bottom View, the Left Side View, and the Rear View. Can you determine where they go? The next drawing shows the relationship of isometric surfaces to the views in orthographic drawings.

What are the 3 main views of the orthographic projection?

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 are the 4 orthographic views?

Orthographic drawings are also known as multiviews. The most commonly used views are top, front, and right side. You can imagine it as positioning yourself directly in front, above, or to the right of an object and drawing only what you can see.
