What are the advantages of orthographic drawings?

What are the advantages of orthographic drawings?

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 are disadvantages of orthographic drawing?

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 some pros and cons of orthographic projection?

Multiview Orthographic

  • Used for: engineering drawings of machines, machine parts. working architectural drawings.
  • Pros: accurate measurement possible. all views are at same scale.
  • Cons: does not provide “realistic” view or sense of 3D form.
  • Usually need multiple views to get feeling for object.

What are the advantages and disadvantages of isometric drawing?

Isometric Projection

  • Used for: catalogue illustrations. patent office records. furniture design.
  • Pros: don’t need multiple views. illustrates 3D nature of object. measurements can be made to scale along principal axes.
  • Cons: lack of foreshortening creates distorted appearance. more useful for rectangular than curved shapes.

What are orthographic drawings?

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 3 main views of 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.

What is the meaning of orthographic?

What is 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.

Why are orthographic drawings important to drafters and engineers?

This is the bread and butter of an engineering drawing. An orthographic view or orthographic projection is a way of representing a 3D object in 2 dimensions. Thus, a 2D view has to convey everything necessary for part production. This kind of representation allows avoiding any kind of distortion of lengths.

What are the disadvantages of isometric drawings?

What are the disadvantages of isometric drawing?

  • 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 6 views of orthographic drawing?

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 is orthographic in engineering drawing?

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.
