E112 | W5L10: 2D Drawings with Autodesk Fusion
About Engineering Drawings
There are different ways to communicate a product design. For example, pencil sketches can be used, but they typically only illustrate key features of a product. These sketches are also not good enough for production purposes.
2D drawings has more information that can help a manufacturer produce the product that is intended. Besides providing clear and precise technical information, very often, drawings are used as legally-binding documents for manufacturing contracts, and are essential for quality control and compliance with standards.
To create engineering drawings, we can use Computer-Aided Design (CAD) software such as Autodesk Fusion to first produce 3D models. We can then translate the 3D models into 2D engineering drawings.
First-Angle Projection vs Third Angle Projection
First Angle Projection
Bottom view is placed on top of the front view
Left view is placed to the right of the front view
Top view is placed below the front view
Right view is placed to the left of the front view
Third Angle Projection
Bottom view is placed below the front view
Left view is placed to the left of the front view
Top view is placed on top of the front view
Right view is placed to the right of the front view
Creating 2D Drawing in Fusion 360
Step 1: DRAWING > From Design: Switch to the Drawing workspace. We will create a drawing from an existing design.
Make sure to select the ASME Standard (which will produce third-angle projections), as opposed to ISO which produces first-angle projections.
Step 2: SAVE an Empty Version: Remember, always save an empty version as proof of your own work!
Step 3: Insert the BASE VIEW: Insert the base view, which is typically the front view. Use a suitable scale, such that even when more information is added into the drawing later, the drawings will take up a good amount of space without looking cluttered.
Step 4: Insert PROJECTED VIEWS: Insert projected views and isometric views. Typically, we should have three views and a fourth 3D isometric view on a drawing.
Step 5: Add in DIMENSIONS and VIEW LABELS. All dimensions must be indicated on the drawing. Each dimension should only be indicated once, i.e. do not dimension the same length twice. You should also label the views. Remember to SAVE YOUR WORK!
