To create another orthographic view, choose Ortho. The program prompts you to specify the side of the viewport to project. Click the bottom edge of the viewport. Then, the program prompts you to specify the view center.
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 do you do orthographic views?
Creating an Orthographic Projection
- Choose a front view. …
- Decide how many views are needed to completely describe the object. …
- Draw the visible features of the front view.
- Draw projectors off of the front view horizontally and vertically in order to create the boundaries for the top and right side views.
- Draw the top view.
How many orthographic views are present in AutoCAD?
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.
How do you make a projection in AutoCAD?
- Click Layout tab Create View panel Projected View. Find.
- Click the drawing view you want to use as the parent view. A preview of a projected view appears at the cursor.
- Move the preview to the desired location and click to place the view. …
- Repeat step 3 until all the required projected view are created.
- Press ENTER.

Is isometric drawing 2D or 3D?
An isometric drawing is a 3D representation of an object, room, building or design on a 2D surface. One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted. This is due to the fact that the foreshortening of the axes is equal.
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 6 orthographic views?
views that are produced by six mutually perpendicular planes of projection. 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 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 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 is Third 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 projection in AutoCAD?
Add to Collection. 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 a first angle projection?
First angle projection is a method of creating a 2D drawing of a 3D object. It is mainly used in Europe and Asia and has not been officially used in Australia for many years. In Australia, third angle projection is the preferred method of orthographic projection. Note the symbol for first angle orthographic projection.

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. … The first thing we need to do is to put AutoCAD in the isometric mode. This mode is entered through the SNAP command.
