Frame Construction

1. Setting Up the Frame
   
   • Use the line tool to trace the frame shape.
   • Enable rendering in viewport for cylindrical geometry.
   • Use the fillet option to round corners.
2. Handle Creation
   
   • Handle rotates from two points (bolts).
   • Create connection brackets using cylinders.
   • Scale and modify cylinders, delete half, apply shell modifier.
   • Add a release button mechanism for handle rotation.
3. Positioning the Frame
   
   • Ensure the frame goes behind the wheel.
   • Confirm the wheel connects to a bracket on the frame.
   • Align the frame with fuel tank contours.
4. Line Drawing and Refinement
   
   • Create a multi-point line using an orthographic view.
   • Refine line with additional vertices for accurate shape.
   • Use snapping (S key) for alignment.
5. Applying Fillet to Frame
   
   • Select vertices and use fillet option to round corners.
   • Adjust each curve individually for proper curvature.
6. Rendering the Frame
   
   • Enable rendering in viewport.
   • Select radial shape, 12 sides, auto-smooth (40°).
   • Ensure caps are enabled for closed geometry.

Symmetry & Positioning

1. Applying Symmetry Modifier
   • Convert line to edit poly.
   • Apply symmetry for mirroring across the X and Y axis.
   • Adjust mirror position to align with frame structure.
   • Extend endpoints for seamless symmetry.

Handle & Bracket Creation

1. Creating the Brackets
   
   • Use cylinders and scale to match the frame’s width.
   • Apply shell modifier for thickness.
   • Reset XForm before adding thickness to avoid deformation.
2. Modeling the Handle
   
   • Create a multi-point line for handle shape.
   • Use fillet tool to round out corners.
   • Apply rendering in viewport for cylindrical form.
   • Convert to edit poly and apply symmetry.
3. Adding the Pivot Bolts
   
   • Create cylinders for bolts and nuts.
   • Align pivot points with snapping for rotation accuracy.
4. Finalizing Handle Functionality
   
   • Adjust pivot for correct rotating point.
   • Test rotation to ensure proper movement.

Release Button Construction

1. Creating the Button
   
   • Use a sphere, remove half, and extend into handle.
   • Adjust rotation to align with handle.
   • Use auto-smooth to fix shading issues.
2. Finalizing the Release Mechanism
   
   • Ensure button fits into handle.
   • Verify correct alignment and functionality.
