In some cases only 2 views are needed, but for anything more than a simple part, 3 or more views are needed. Very complex parts will need 6 or more.
How many views do you need orthographic projection?
The image of point O is projected onto the projection plane and a two-dimensional view of the point can be drawn. To completely define an object, at least two orthographic views are required. Depending on the complexity of the part, three or more views are required.
What is orthographic projection in Autocad?
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 are the limitations of orthographic projection?
Limitations. Orthographic drawings do not show depth or realistic views. A single-view orthographic drawing represents every object as having only two dimensions.
What are the 4 orthographic views?
An orthographic projection is a way of representing a 3D object by using several 2D views of the object. Orthographic drawings are also known as multiviews. The most commonly used views are top, front, and right side.
What are the three regular views?
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 3 regular views of an object?
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 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 is meant by orthographic projection?
1 : projection of a single view of an object (such as a view of the front) onto a drawing surface in which the lines of projection are perpendicular to the drawing surface.
What are the limitations of isometric projection?
Disadvantages Of Isometric Projection:
- It creates a distorted appearance by lack of foreshortening.
- It is more useful for rectangular than curved shapes.
- It distorts shape and depth.
- Instead of the real view it only provides a 2D view.

What are the advantages of orthographic drawing?
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 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 are the six basic 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 two main types of projection?
The most common types are the perspective and orthographic projections.
Who uses orthographic projection?
They are used to show an object from every angle to help manufacturers plan production. Starting with a front view of a product, construction lines show where areas join and are used to draw a side and plan (top) view, ensuring that the drawing is accurate from all angles.
