# Orthographic Projection Examples Pdf

It may be drawn in the position of a horizontal plane passing through, above, or below the object. The plan view is a view seen directly from above. In particular, the fact that the inner circle is drawn with a solid line instead of dashed identifies this view as the top view, not the bottom view. Such a view might be desired for calculating clearances or for dimensioning purposes.

## Multiview projection

Opposite is a simple L-shape, drawn in three dimensions. It is standard throughout Europe and Asia excluding Japan.

Solved examples with detailed answer description, iec 60227 pdf explanation are given and it would be easy to understand. To obtain this view without multiple rotations requires the principles of Descriptive Geometry.

This produces two plans and four elevations. This article needs additional citations for verification. Below is an example of F irst Angle projection. In other projects Wikimedia Commons.

Sliding the object up the right edge of the bowl reveals the right side view. However this is not the correct way of drawing them as they are not in the right positions. In the building industry elevations is a non-perspective view of the structure.

For mathematical discussion in terms of linear algebra, see Projection linear algebra. Plan drawing and Floor plan.

Drawing sets include front, rear, and both side elevations. Current Affairs Interview Questions and Answers.

Please help improve this article by adding citations to reliable sources. Normally when drawing in first or third angle projection a symbol is drawn underneath which clearly shows which angle of projection has been used. The red lines are faint guidelines and they are drawn to help keep each view in line, level and the same size. Often, it is more useful to use homogeneous coordinates.

The box is then unfolded to view all of its exterior walls. Select a simple three dimensional object and draw it in first angle projection.

Here is the construction of third angle projections of the same object as above. The steps below describe the use of these principles in third angle projection. Two Thousand Years of Map Projections pp.

Visualization of technical information. The drawing is composed of a front, side and plan view of the L-shaped object. In cases where such a view is useful, e.

Sliding the object down the right edge of the bowl reveals the right side view. The addition of a third plane to show a side view either left or right is a modern extension.

Usually a front, side and plan view are drawn so that a person looking at the drawing can see all the important sides. Suppose a technician desired such a view to, say, look through a hole to be drilled perpendicularly to the surface. These are drawn to scale so that measurements can be taken for any aspect necessary. Interior elevations are used to show details such as millwork and trim configurations.
