Cuban Chain 3D model in Rhino 6 (2018)- Jewelry CAD Design Tutorial #26

Introduction

In this tutorial, we will learn how to model a Cuban chain using Rhino 6, a popular 3D modeling software. While 3D printing chains isn't common, knowing how to create a Cuban chain is essential for rendering purposes, especially when combined with pendants. This guide will provide step-by-step instructions to help you effectively model Cuban links and can be applied to create other types of chains as well.

Step 1: Setting Up Your Workspace

• Open Rhino 6 and create a new project.
• Set your units of measurement according to your preferences (e.g., millimeters or inches).
• Familiarize yourself with the interface and tools relevant to modeling, such as the Curve and Surface tools.

Step 2: Creating the Base Link Shape

• Start by drawing a circle using the Circle tool. This will represent the cross-section of your chain link.
  • Use a radius that suits your design.
• Duplicate the circle to create multiple links. Use the Copy command for this.

Step 3: Forming the Link Structure

• Select one of the circles and use the Extrude command to give it thickness.
• Adjust the height of the extrusion to match your design preferences.
• Use the Scale tool to modify the link shape, making it slightly oval for a more realistic Cuban chain appearance.

Step 4: Arranging the Links

• Position the links in a sequence to form the chain.
• Use the Rotate and Move commands to align the links properly.
• Ensure that the links are interconnected by overlapping them slightly.

Step 5: Adding Details

• For added realism, use the Fillet tool to round off the edges of the links.
• Adjust the fillet radius to create a smoother transition between links.
• Optionally, you can add surface textures or patterns using the Surface tools for a more intricate design.

Step 6: Finalizing the Model

• Review the entire chain for any inconsistencies in link placement or shape.
• Use the Join command to merge the links into a single object.
• Save your work frequently to avoid losing progress.

Conclusion

You have now created a Cuban chain model in Rhino 6! Remember to explore additional features in Rhino for enhancing your design, such as rendering options to visualize the chain with a pendant. Practice these steps to refine your skills, and consider experimenting with different styles or designs of chains.
