It shows the object with a top view, a front view and a side view. These three views are ‘projected’ and aligned with each other.
What is orthographic view in AutoCAD?
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 many orthographic views are there?
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.
How do you make an orthographic view in AutoCAD?
On the ribbon, click Home tab Ortho Views panel Create Ortho View. Note: Alternatively, you can click the Orthographic DWG tab in the Project Manager, open an orthographic drawing, and, on the ribbon, click New View.
What are the multi views in CAD?
Multi-view blocks typically represent 3D architectural objects. For example, you can create customized cabinetry by drawing plan, elevation, and model views, and saving each view as an individual AutoCAD block. You assign each block to a view when you create the multi-view block definition.
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 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 Projected views can be derived from any existing view, as long as the existing view is not out-of-date or unresolved.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 are the 3 planes of projection?
[FIGURE 3-2] Projections of the point are made onto three of the surfaces that make up the box: the top or “H” (horizontal) plane, the front or “F” (frontal) plane, and the right side or “P” (profile) plane.
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 main types of projection?
The most common types are the perspective and orthographic projections.
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.
How do I create a multi view drawing in AutoCAD?
To Create Multiple Drawing Views
- In the Browser, choose the Drawing tab. …
- Double-click a Layout to make it the active layout.
- Right-click the Layout icon, and then choose New View.
- In the Create Drawing View dialog box, …
- Select the location of the projected view.
- Continue placing as many views as desired.
- Press ENTER to exit the command.
What is multi view drawing?
A Multiview drawing is one that shows two or more two-dimensional views of a three-dimensional object. Multiview drawings provide the shape description of an object. When combined with dimensions, multiview drawings serve as the main form of communication between designers and manufacturers.
What methods are used to space views on a drawing?
The two projection methods primarily used are perspective and parallel. (Figure 8.1) Both methods are based on projection theory, which has taken many years to evolve the rules used today. Projection techniques developed along two lines: parallel and perspective.
How do you decide which views are necessary for a multi view drawing?
How do you decide which views are necessary for a multi-view drawing? In creating multiview orthographic projection, different systems of projection can be used to create the necessary views to fully describe the 3D object.
