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.
How do you make an orthographic view in AutoCAD?
To Create an Orthographic View (AutoCAD Mechanical Toolset)
- In the Browser, right-click the Base view icon, and then choose New View. …
- In the Create Drawing View dialog box, select the view type Ortho, and choose OK.
- Select a location for the orthographic view directly below the base view, and then press ENTER.
What does orthographic view mean?
The definition of an orthographic projection is a two-dimensional drawing of a three-dimensional object, using two or more additional drawings to show additional views of the object.
What is orthographic view 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.
How many orthographic views are present in AutoCAD?
After you create a three-dimensional part, you may need to create two-dimensional orthographic views of the 3D model in order to produce working drawings. There are a number of ways to do this in AutoCAD. One of the methods uses three related tools: Solid View, Solid Drawing, and Solid Profile.
What is orthographic projection used for?
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 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 two types of orthographic projections?
First angle projections and third angle projections are the two main types of orthographic drawing, also referred to as ‘working drawings’. The difference between first and third angle projection is in the position of the plan, front and side views.
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 types of projection?
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. Axonometric is another type of orthographic projection. …
- Oblique Projection. …
- Perspective Projection.
Who uses orthographic projection?
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 is projection in AutoCAD?
Orthogonal and isometric drawing views generated from an existing drawing view are referred to as projected views. Projected views can be derived from any existing view, as long as the existing view is not out-of-date or unresolved.
What is isometric drawing in AutoCAD?
An AutoCAD isometric drawing is a 2 dimensional drawing just like a paper drawing. AutoCAD provides some tools to aid us in creating the drawing, but not very many. Mostly, we will be using the same commands that we used in creating orthographic drawings.
What does 3rd angle projection mean?
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.
