Exploded views are a commonly used type of patent drawing that show how different components of an invention fit together. They are particularly useful for complex inventions that have multiple parts or layers. In an exploded view, the components of the invention are separated from each other, often with some space between them, so that each part can be clearly seen and understood.

If you are filing a patent application, it is important to include clear and accurate exploded views of your invention. Here are some tips on how to present exploded views in patent drawings:

1. Choose the right angle: When creating an exploded view, it is important to choose an angle that shows the relationship between the various components of the invention clearly. Typically, a perspective view is used, but other angles can be used as well. It is important to choose an angle that is easy to understand and that clearly shows how the components fit together.
2. Use consistent spacing: When creating an exploded view, it is important to use consistent spacing between the components. This helps to ensure that the relative size and position of each component is clear and easy to understand. The spacing should be uniform and should be clearly labeled in the drawing.
3. Use callouts: Callouts are labels or arrows that point to specific components in the exploded view. They are often used to label individual parts or to show how they fit together. Callouts should be clear and easy to read, and should be positioned so that they do not obscure any important details.
4. Use shading: Shading can be used to add depth and dimensionality to an exploded view. This can help to make the various components of the invention more visually appealing and easier to understand. It is important to use shading consistently and to make sure that it does not obscure any important details.
5. Use appropriate line weights: The line weight of the drawing should be appropriate to the size and detail of the components. Thicker lines are typically used for larger parts or to highlight important details, while thinner lines are used for smaller parts or to show less important details.
6. Include a list of parts: Finally, it is important to include a list of parts with the exploded view. This list should clearly identify each component of the invention and should include any relevant dimensions or other important details.

By following these tips, you can create clear and accurate exploded views that will help to make your patent application more effective. Remember to consult with a patent attorney or agent to ensure that your drawings comply with all the requirements of patent law.
