Projection Drawings

Projection drawings are accurate and detailed drawings that are used to communicate scale, dimensions, parts, and assemblies. They are two main types of Projection Drawings:

Orthographic Drawing: A series of drawings that show the exact shape and size of an object. Typical orthographic drawings show three views of an object: Side, Top and Front. These drawings include details and dimensions, and are used to guide the construction of making of an object. They are sometimes called production drawings or working drawings.
Isometric Drawing: A drawing that shows the object represented in 3D space. They are always drawn on a 30/90/30 degree access. Typically, they do not include measurements, but would include annotations about the form, function, materials, etc.

Creating Orthographic Drawings in CAD Software

Orthographic drawings are always presented in a specific format. By following this format, your drawings can be interpreted by another person accurately.

In order to create drawings of the object at the right, you can use the planning drawing function in your CAD software. Remember, the aim of these drawings is to communicate information about the object so that another person could create it.

Top Left = Top view of the object

Bottom Left = Side view of the object

Bottom Right = Front view of object

Top Right = Isometric View

Your final drawings should look like below:

Your drawings should include:

three orthographic views
1 isometric view
relevant dimensions
relevant angles
relevant annotations

If your design has multiple parts, these should be shown as additional drawings

Creating Planning Drawings in Fusion 360

Fusion 360, like most CAD software, can be used to create planning drawings.

Watch the video below for a short tutorial:

Creating Orthographic Drawings by hand

You may create drawings by hand. These may be done in the early stages of your design exploration, or as you are exploring what a design might look like. For example, in Criteria B2 and B3 of the MYP design cycle, you might hand draw your design ideas in order to explore.
