Fuel Filter, Air Filter, and Choke Components
1. Modeling the Fuel Filter Bracket
- Use the Line Tool to trace the outline of the bracket.
- Ensure symmetry by drawing one side and mirroring it.
- Attach a circular cutout to the line model.
- Use Refine to add vertices at intersections.
- Delete unnecessary internal line segments.
- Weld overlapping vertices to create a closed spline.
- Apply Fillet to round out sharp corners.
- Convert the spline into a polygon and apply Shell for thickness.
- Create a box shape in the center and align it.
2. Shaping the Fuel Filter Bracket
- Adjust the box’s height and width based on the reference.
- Delete the bottom face to save geometry.
- Add Chamfer to the edges to soften transitions.
- Reset X-Forms to ensure uniform scaling.
- Use Inset and Bridge to add guiding edges.
- Apply smoothing groups to achieve realistic lighting transitions.
- Attach the bracket and align it to the generator.
3. Creating the Fuel Filter
- Create a cylinder and align it with the bracket.
- Adjust the radius and height to match the reference.
- Use Chamfer on the bottom edge.
- Duplicate the existing hex bolt for attachment.
- Use the Create Shape from Selection tool to generate an O-ring.
- Enable Viewport Display and adjust the thickness of the O-ring.
- Scale and align the O-ring properly.
4. Adding the Fuel Filter Cap
- Inset and scale the top of the cylinder to create a lip.
- Extrude upwards to form the cap’s body.
- Add a box on top of the cap for additional details.
- Align the box properly and adjust proportions.
- Chamfer the bottom edge of the filter for smooth transitions.
- Attach the cap and filter body as one object.
5. Positioning the Fuel Filter Assembly
- Adjust rotation and position to fit behind the air filter.
- Ensure the cap is aligned with the reference images.
- Use Edit Poly to fine-tune height and placement.
- Duplicate and place a nut at the bottom for securing the filter.
6. Creating the Air Filter Box
- Start with a simple box and scale it accordingly.
- Adjust its depth and position to match reference images.
- Apply beveling to the edges to match the soft metal structure.
- Skip unnecessary details like the latch mechanism since it's a proxy.
7. Adding the Choke Lever
- Create a simple floating piece to indicate choke functionality.
- Position it near the air filter for accurate representation.
