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 Projected views can be derived from any existing view, as long as the existing view is not out-of-date or unresolved.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 projected views?
Projected views are created by folding off an existing view in one of eight possible projections. The resulting view orientation is affected by the setting of First angle or Third angle projection as defined in the drawing sheet properties.
What is isometric projection in AutoCAD?
Isometric drawings are not actual 3D drawings, they are made with 2D geometries but they appear like 3D. Isometric drawing in AutoCAD can be made by tilting viewing angle to 30 degrees for all of its sides in the 2D plane.
What are objects in AutoCAD?
Object properties control the appearance and behavior of objects, and are used to organize a drawing. Every object has general properties including its layer, color, linetype, linetype scale, lineweight, transparency, and plot style. In addition, objects have properties that are specific to their type.
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.
How do you create an orthographic projection?
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.
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 types of projections?
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 first angle projection?
Third angle projection (figure 1.2) is used mainly in The United States and Canada whilst first angle projection (figure 1.1) is used mainly throughout Europe and the rest of the world.
What are the examples of isometric drawing?
Here are some examples of isometric drawings. Notice that each image shows three axes to represent each dimension of the object: the vertical axis is blue and two horizontal axes are drawn in orange and green.
Is isometric drawing true 3d drawing?
Isometric drawings are 3D drawings. They show three sides, all in dimensional proportion, but none are shown as a true shape with 90 degree corners. All the vertical lines are drawn vertically but all horizontal lines are drawn at 30 degrees to the base line.
What is the definition of isometric?
1 : of, relating to, or characterized by equality of measure especially : relating to or being a crystallographic system characterized by three equal axes at right angles.

What is AutoCAD designer?
AutoCAD Drafters specialize in creating Computer-Aided Design (CAD) models using Autodesk’s AutoCAD software. These highly-trained draftsmen work with architects and engineers to design and create 2D and 3D computer models of buildings and machine parts from blueprints or from scratch.
How many layers should a drawing have?
Layer 0 cannot be deleted or renamed to ensure that every drawing includes at least one layer. In general, you should always create several new layers with which to organize your drawing, rather than create your entire drawing on layer 0. These layers can be saved in a drawing template (a file with a .
