Orthographic Projection

What is an ortho proj.

• a method of projection in which an object is depicted or a surface mapped using parallel lines to project its shape onto a plane.

The common view

• The most common view in an orthographic projection is the isometric (3D image), top view, front view, and the right side view.

Third angle projection

• The third angle projection is the same as the first angle projection only laid out on the plan differently.

Hidden lines

• A line used to define a part feature that is not visible in a specific view. Hidden lines consist of a series of short dashes.

The bowl method

• The bowl method is a method of seeing the three views (front top and right side).

The Layout

• the layout is how the orthographic projection is shown the isometric view on the top right, the top view on the top left, the front view on the bottom left, and the right side view in the bottom right.
