In orthographic sketches, a rib is outlined with object lines instead of being hatched to clearly distinguish its edges and shape. Hatching is typically used to indicate areas of solid material or sections in a cross-sectional view, while ribs are often represented to show their dimensional characteristics without implying additional material. This approach helps maintain clarity and ensures that the rib's geometry is easily understood in the context of the overall design.

All drawing is a form of projection in itself. If you mean how do you project orthographic shapes to trace then the best way would be to place a light 180 degrees behind the object you wanted to draw. This would cast a silhouette (which is essentially what an orthographic drawing is) that you can trace.
Orthographic sketches are usually in a 3-D form. This type of drawing is sometimes done on graph paper and shows a cut-away version of an object.

An orthographic image is a three-dimensional object. Orthographic blueprints are used for the different views like the front, side, top, bottom and rear. Using blueprints when creating an orthographic image allows you to be much more accurate with the result than if you didn't use them.
You can find information on orthographic projection at the Wikipedia. Once on the website, type "Orthographic projection" into the search field at the top of the page and press enter to bring up the information.

Six views are possible for an orthographic drawing, though three views are usually enough.
orthographic drawing is a drawing that communicates the shape and size of an object through a series of related two-dimensional views.

these projections have dimensions
I said that I need 5 examples of an orthographic drawing and you gave me no answer, how smart can you be? and you are telling me to sign. i say give me my answer now
