Understanding Orthographic View in Fusion 360
Orthographic projection is a method of representing three-dimensional objects in two dimensions, where views are displayed from different angles without perspective distortion. In Fusion 360, this technique is primarily used to create technical drawings. This guide will provide you with detailed instructions on how to set up and modify your orthographic views effectively.
Steps to Set Up Orthographic Projection
Open Your Design: Launch Fusion 360 and open the design that you wish to work on. Make sure that the component you want to generate views for is in a proper orientation.
Access the Drawing Environment:
- Click on the “File” menu situated in the upper left corner.
- Select “New Drawing” and then choose “From Design” to create a new drawing based on your current model.
New Drawing Dialog: A dialog box will appear prompting you to configure your drawing settings. Here, you can customize your drawing according to your project requirements.
Select Contents:
- In the Contents dropdown menu, choose the components you wish to include in your orthographic projections.
- Ensure that you select the correct scale and units for the drawing.
Destination Settings: Adjust the destination settings as needed, including the paper size and layout orientation (landscape or portrait). Once satisfied, click "OK" to proceed.
Placing Views in the Drawing:
- Once the drawing canvas is available, you can select the desired view types from the drawing toolbar. Choose the projected view, which allows you to create front, top, and side views in accordance with the orthographic projection.
- Click on the main view, then drag to specify the placement of ancillary views.
- Adjust the Views: You may need to reposition the views to ensure they are neatly aligned. Use the view manipulation tools available in the toolbar for this.
Switching to Orthographic Display Mode
Change Display Settings:
- Navigate to the Display Settings located in the toolbar.
- Switch the view mode to "Orthographic View" to eliminate perspective distortions.
- Using the View Cube:
- The View Cube in the top right corner of the workspace helps in controlling the orientation of the model.
- Click on the corners of the View Cube to switch between different orthographic views (front, top, left, right, etc.).
Accessing Isometric View
- Setting Up Isometric View:
- For an isometric view, which can also be useful in conjunction with orthographic views, simply click on the corner of the View Cube or switch to the predefined isometric settings in the Display settings.
- After switching views, you will be able to manipulate the scene to your desired angle while retaining orthographic projections.
FAQs
1. What is the difference between First Angle and Third Angle Projection?
First Angle Projection places the object between the observer and the projection plane, while in Third Angle Projection, the object is situated behind the projection plane. This results in different placements of top and side views in technical drawings.
2. How can I add dimensions to my orthographic drawing in Fusion 360?
You can add dimensions by selecting the "Dimension" tool in the drawing environment. After clicking on the points or edges you want to measure, place the dimensions accordingly to annotate your drawing.
3. Can I convert a 2D sketch into an orthographic projection?
Yes, you can use the "Convert" feature to transform a 2D sketch into its respective orthographic views. This is particularly helpful for creating detailed technical drawings from existing sketches.
