Making signet rings and bas relief medallions in CAD can be tricky, until now. Join us for a course focused on learning the bas relief surfacing techniques required to make signet rings and medallions using Rhino.

This course is intended for individuals who have already started learning Rhino or Matrix, but would like to focus on learning how to build more sculptural medallions and signet rings in CAD, perhaps for the purpose of decorating with pave. These techniques are ideal for individuals keen on working with bas relief modelling, animal sculpture, or hip hop jewellery.

Students who already know the basics of Rhino or Matrix will learn how to use advanced surface creation and control techniques to build the smooth sculptural elements required to make bas relief and signet rings. We will also take a moment to discuss adding pave or surface textural elements in Rhino.

On the last day of the course, there will be time for the students to bring in their own project to work on to practice what they’ve learned.

Intermediate Rhino CAD Topics Will Include

    • Control Point sculpture on NURBS Surfaces
    • Creating bas relief forms with Sweep and Loft
    • 3-dimensional control of curves
    • Two methods to build any Signet Ring
    • Hollowing out a constructed form
    • Applying pave in Rhino
    • Flow Along Surface

On the last day of the course, there will be time for the students to bring in their own project to work on to practice what they’ve learned.

Course Length
3 days


Upon completion of this course and approximately 4-6 weeks of steady practice in your own time, there are several additional classes and masterclasses which would be greatly beneficial to you.

Rhino CAD Intermediate would allow you to progress onto the next level of skill with Rhino CAD software, bringing in more advance surface editing techniques and the basics of sculpture.
Adobe Illustrator for Jewellery Design makes for an excellent secondary program, giving Rhino users a superior method for designing and controlling drawings and logos created using vector graphics. This short course would provide complimentary 2D tools to go with their 3D tool set.
A 1-to-1 masterclass in T-Splines for Rhino would explore using the subdivision modelling tool for controlling organic shapes and freeform sculpture.
A 1-to-1 masterclass in V-Ray Rendering For Rhino would give students a grounding in essential rendering techniques for making photorealistic renders of their 3D models.
A 1-to-1 masterclass in Z-Brush will give students an extra piece of software with which they can apply texture and more sculptural modelling practices to their existing 3D models.

The British Academy of Jewellery also offers a diverse range of specialist intensive courses to help individuals develop their jewellery knowledge and skillset in areas such as CAD, gemstone studies and technical drawing.

If you are considering a professional career in jewellery-making, we recommend our Jewellery Diploma Programme, which will equip you with all the knowledge and skills you need to design, make and sell jewellery.
