v Orthographic drawingØOrthographic drawings are orthographic projection drawings. These can be drawn at first angle projection and third angle projections.ØI am going to explain orthographic third angle projection drawing because I use them.ØIf I want to draw orthographic third angles projection drawing I have to follow some rules.ØThese rules are:ØThe view from the front is in the middle.ØThe view from the left is on the left.ØThe view from the right is on the right.ØThe view from the top is on the top.ØThe view from the bottom is on the bottom.ØThe view from the rear/back is on the far right.Example of orthographic third angle projection.Orthographic drawing advantageOrthographic drawing disadvantageEasy to recognized /read and understand by engineers.Hard to recognized by other people then engineers.Doesn't looks like at all to real design/picture.

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.
what is orthographic sketching all about?
orthographic
The purpose of an orthographic drawing is to accurately represent an object in two-dimensional form using multiple views (front, side, top, etc.). This allows for a clear and detailed representation of the object's shape and dimensions for design and communication purposes.

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.
These principles are usually taught in a drafting class, but may be taught in advanced art as well. Orthographic views may be drawn out on a page to show top, front and side views of an isometric drawing that is also drawn on the page as well. This is a basic drafting design setup.

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.
