Both formats build on each other.
Reading helps you understand why each step matters, while watching shows how to move faster in Fusion.
Step 1: Start with a Simple Sketch
Begin by activating a new internal component. This keeps your design structured and easier to manage later, especially if you plan to reuse or modify the model.
Create a new sketch on a vertical construction plane. This orientation aligns naturally with how a tire sits and makes it easier to visualize the final shape.
Keep the sketch simple—just two lines forming an open profile. This works because we’ll use surface modeling, which doesn’t require closed profiles like solid modeling does.
Leave some distance from the origin. You’ll use the center axis as your revolve axis, so spacing helps avoid constraints or alignment issues later.
A constrained sketch defines the cross-section of the tire before revolve. Dimensions control width and height, ensuring predictable geometry when the profile is revolved around the center axis. Keeping the sketch fully constrained prevents shape distortion when modifying parameters later.
Step 2: Revolve the Surface
Use the Revolve command in the surface workspace.
Surface revolve is the right choice here because it allows you to revolve an open profile. The solid version would require a closed shape, which adds unnecessary complexity at this stage.
Set:
- Axis: center construction line
- Extent Type: Full
This creates the base shape of your tire as a surface body.
Use the view cube to inspect your model from multiple angles. This is faster and more controlled than orbiting blindly, and helps catch issues early.
The profile is revolved 360 degrees around a vertical axis to generate the base tire shape. Using a single clean profile avoids surface artifacts and ensures a uniform solid. Selecting the correct axis is critical, as misalignment results in asymmetric geometry.
Step 3: Add Fillets for Shape
Apply a fillet to the outer edge.
At this stage, the goal isn’t perfection—it’s form. Fillets soften transitions and quickly give your model a more realistic tire profile.
Avoid over-tuning settings. Once the workflow is complete, you can always return and refine dimensions.
A fillet smooths the outer edge of the tire to create a rounded transition. Tangent chain selection ensures continuity across connected edges. Fillet radius directly influences the perceived softness and realism of the tire surface.
Step 4: Convert Surface to Solid with Thicken
Use the Thicken command.
This is one of the most important tools when working with surfaces. It turns your surface into a solid body while maintaining control over wall thickness.
Set a negative value (e.g. -5 mm) to thicken inward. This keeps your outer shape intact while building the solid volume internally.
The thicken tool adds material to a surface body, converting it into a solid with defined wall thickness. Direction and thickness values control how the material grows relative to the original surface. Maintaining consistent thickness is important for manufacturability and print reliability.
Step 5: Refine the Inner Geometry
Use Extrude Cut to remove material from one side.
This helps define the internal structure of the tire and gives more control over thickness and proportions.
An extrude cut removes material from the inner region to form a recessed channel. The cut is driven by a selected profile and controlled depth, allowing precise shaping of internal features without affecting the outer geometry.
Add another fillet where needed to maintain smooth transitions. Clean geometry here improves both appearance and downstream operations like patterns and rendering.
A secondary fillet refines the inner edge, removing sharp transitions that could cause stress concentrations or poor print results. Consistent edge treatment improves both aesthetics and structural behavior.
Step 6: Rebuild Geometry with Project
If you can’t select a face for extrusion (often due to fillets or topology), don’t fight the geometry.
Instead:
- Create a new sketch on a construction plane
- Use Project to capture existing edges
Existing edges are projected into a sketch to create associative geometry. The projection link keeps the sketch updated if the underlying model changes, supporting a parametric workflow and reducing the risk of broken references.
Projected geometry (shown in purple) stays linked to the original model. This is critical for parametric workflows—if you update earlier features, your sketch updates automatically.
Extrude twice:
- First: 4 mm
- Second: 2.5 mm
Set both to New Body. Keeping bodies separate gives you more flexibility for patterns, appearances, and later edits.
A profile is extruded outward to form an additional ring feature as a separate body. Using a new body operation allows independent control and later combination or modification without affecting the base geometry.
The extrude operation is set to New Body , separating material from the existing body. This approach separates the new geometry seamlessly and maintains separated solids for downstream operations.
Step 7: Improve Visibility with Shaded Modes
Press Ctrl + 5 to enable Shaded with Hidden Edges.
This view mode reveals internal edges between bodies, making it easier to understand how your model is structured. It’s especially useful before applying operations like cuts or patterns.
Initial groove features are established on the tire surface prior to duplication. Creating a clean base feature simplifies pattern operations and ensures consistent spacing and orientation.
Step 8: Create Tire Tread with Pipe
Use the Pipe tool along edges between bodies.
The Pipe tool isn’t just for adding material—it can also remove it. Fusion often suggests the correct operation automatically based on context.
Use it here to cut into the tire and create tread features. Since the geometry is already defined, this method is faster and cleaner than sketching from scratch.
The pipe tool follows a selected path to remove material along the tire surface. Using cut mode enables precise groove creation with a circular cross-section, useful for continuous tread features.
The section size parameter controls groove width in the pipe operation. Adjusting this value changes the visual weight and functional depth of the tread pattern.
Step 9: Add Shoulder Pattern with Emboss
Create an offset construction plane above the tire.
An offset plane is constructed at a defined distance from an existing face. This provides a stable reference for sketches and features that cannot be easily created on curved geometry.
Sketch an overall slot. This tool is versatile and quick for creating elongated shapes, making it ideal for tire patterns.
A slot profile defines the shape of individual tread elements. Positioning and constraining the sketch relative to the tire ensures consistent placement when patterned.
Use Emboss with the Deboss option.
Deboss is perfect here because it removes material directly along curved surfaces without needing complex projections or cuts. It conforms to the tire’s curvature automatically.
The emboss feature wraps the sketch profile onto the curved tire surface, creating recessed or raised geometry. This method preserves curvature and avoids distortion common with planar extrusions.
Step 10: Pattern the Features
Use a Circular Pattern.
Set:
- Object Type: Features
- Axis: center axis
- Distribution: Full
- Quantity: ~36
Using features instead of bodies ensures that updates to the original deboss automatically propagate through the entire pattern. This keeps your design flexible and easy to adjust.
A circular pattern replicates the tread feature evenly around the tire axis. Quantity and distribution settings control spacing and ensure uniform coverage across the surface.
Step 11: Apply Appearance Efficiently
Search for a rubber-like material (e.g. weathered rubber).
Select all tire bodies at once and apply the appearance in one step. This is faster and ensures consistency across the model.
Applying appearance at this stage helps you evaluate proportions and details visually before moving on.
Material appearance is applied to simulate rubber properties. Assigning appearance at the body level ensures consistency across all faces and improves visualization in render mode.
Step 12: Add Tire Markings
Create a new sketch on the outer surface.
A shaded view provides a quick visual check of surface quality and feature integration. This stage is useful for identifying inconsistencies before adding fine details.
Use Project again to capture geometry, then offset it to create a path.
Inner edges are projected into a new sketch to define reference geometry for additional features. Maintaining projection links ensures updates propagate correctly through the model.
The offset tool generates a parallel curve at a controlled distance from the original edge. This defines consistent spacing for features such as text or grooves.
Switch text type to Text on Path and add your tire markings.
Text is placed along a circular path to simulate tire sidewall markings. Alignment and spacing settings control readability and fit along the curvature.
Extrude the text as New Bodies.
This is key:
- Keeping text separate allows you to apply different appearances
- It also makes it easier to edit or remove later
The text profile is extruded to create raised sidewall markings. Careful depth selection ensures visibility without compromising surface integrity.
Select all text bodies at once and apply a white matte appearance. This creates strong visual contrast with the tire.
A contrasting material is assigned to the text bodies to improve visibility. Separating text as distinct bodies allows independent appearance control.
Step 13: Mirror the Model
Create a new offset plane at the back.
A new construction plane is aligned with the side of the tire to support symmetric operations. Proper plane placement is essential for accurate mirroring.
Use Mirror:
- Select all bodies
- Mirror across the new plane
- Operation: Join
Mirroring saves time and guarantees symmetry. It also ensures that any updates to one side can be replicated cleanly.
Bodies are mirrored across a central plane to complete the model symmetrically. Using body-level mirroring ensures all features are duplicated consistently.
Step 14: Final Rendering Setup
Switch back to Shaded view (Ctrl + 4).
Open Scene Settings:
- Change background to Environment
- Choose a suitable environment (e.g. Crossroads)
The render workspace is used to preview lighting and environment reflections. Selecting an appropriate environment enhances realism and highlights surface details.
Set resolution to 1920 × 1080 and render.
Take time to test angles before rendering. With text and details, readability matters as much as lighting.
Render settings define resolution, aspect ratio, and quality for the final output. Adjusting these parameters balances image fidelity with rendering time.
