Getting Started with Rhino 8: A Toy Car Speed Build

In the realm of 3D modeling, Rhino 8 stands out for its versatility and powerful tools, making it a favorite among designers and modelers. This article explores a practical application of Rhino 8 through the step-by-step process of creating a die-cast toy car model. The focus will be on various modeling techniques, including NURBS modeling, SubD modeling, and shrink wrapping, while providing insights into effective modeling strategies.

Introduction to the Project

The project begins with the intention of building a toy car model, specifically a die-cast Formula 1 car. The presenter, a seasoned toy designer with extensive experience in the industry, emphasizes the importance of spontaneity in the modeling process. The goal is to create an impressive model within a limited timeframe, showcasing the capabilities of Rhino 8.

Setting Up the Workspace

Before diving into the modeling, the presenter sets up the workspace by importing reference images of the toy car. This step is crucial as it serves as a visual guide throughout the modeling process. Using the picture command in Rhino, the images are brought into the scene and positioned appropriately.

The images are then locked in place to prevent accidental selection during the modeling. This simple yet effective organizational step allows for a smoother workflow.

Modeling Strategy

With the images in place, the presenter discusses the modeling strategy. The approach will involve a combination of NURBS and SubD techniques, utilizing various tools available in Rhino 8. The objective is to create a toy model suitable for 3D printing without getting bogged down in intricate details.

The presenter outlines the plan to use a technique referred to as “smash and mash modeling,” which involves quickly assembling components and refining them later. The use of the shrink wrap tool will be central to this process, allowing for the combination of multiple parts into a single, unified model.

Creating the Body of the Car

To begin modeling the car’s body, a straight line is drawn to establish the bottom profile. The presenter utilizes the change degree command to modify the curve’s degree, ensuring smooth transitions. By pulling points on the curve, the general shape of the car’s body starts to take form.

After establishing the basic outline, the presenter mirrors the curve to create the opposite side of the car. This technique ensures symmetry and saves time in the modeling process. A loft command is then employed to create a surface that represents the car’s body.

Detailing the Cockpit

Next, attention turns to the cockpit area of the car. The presenter adds panel lines and splits surfaces to define the shape more accurately. The use of the shrink trim surface command allows for easier point editing, facilitating adjustments to achieve the desired cockpit design.

As the cockpit shape takes form, the presenter emphasizes the importance of visualizing the model from different angles. This step ensures that the design remains consistent and true to the reference images.

Building the Interior

With the exterior of the car established, the focus shifts to the interior. The presenter demonstrates how to extrude edges to create the cockpit’s interior space. By using the planar surface command, a closed object is formed, ensuring that there are no naked edges that could complicate the 3D printing process.

Throughout this section, the presenter shares tips on using the isolate command to hide unnecessary elements, streamlining the modeling process.

Creating the Engine and Details

The next phase involves modeling the engine components. The presenter starts by creating tube headers using the pipe command. The focus remains on speed and efficiency, with the understanding that details can be refined later.

Blending surfaces and ensuring that seams align correctly is crucial for a smooth final product. The presenter highlights the importance of maintaining the right direction for surface blends, which significantly impacts the overall shape of the model.

Wheels and Final Touches

As the model nears completion, the wheels become the next focus. The presenter explains how to draw the wheel profile in side view, allowing for an accurate representation of the tire and rim. By revolving the drawn profile, a full wheel is created, which is then scaled to fit the model accurately.

The spokes are modeled to be chunky and toy-like, adhering to design principles that cater to the toy industry. The presenter demonstrates how to use array polar to replicate the spokes around the wheel, ensuring a consistent design across all four wheels.

Finalizing the Model with Shrink Wrap

With the wheels and other components in place, the presenter discusses the finalizing step: using the shrink wrap command. This tool allows for the unification of all parts into a single watertight mesh, perfect for 3D printing. The presenter demonstrates how to adjust the mesh settings to achieve a clean, detailed final model.

Throughout this process, the importance of iterative modeling is emphasized. The ability to make quick adjustments and refinements without the need for extensive trimming or Boolean operations allows for a more efficient workflow.

Wrapping Up

The session concludes with a completed toy car model, showcasing the power and efficiency of Rhino 8’s modeling capabilities. The combination of NURBS and SubD techniques, along with the innovative use of the shrink wrap tool, allows for a streamlined approach to 3D modeling.

For anyone looking to enhance their skills in 3D modeling, this session serves as an excellent example of how to leverage the tools available in Rhino 8 to create high-quality models quickly and effectively.

As the presenter wraps up, they encourage viewers to explore and experiment with Rhino 8, emphasizing that the best way to learn is through practice and exploration. The session leaves a lasting impression on the importance of creativity and adaptability in the design process.
