Prongs, Cutters & Render Prep

11. Generate prongs for the pavé setting

In the Prongs tab set diameter 0.6 mm, overgirdle 0.3 mm, undergirdle 0.4 mm and a 0.5 mm manufacturing extension, then click Automatic Prongs. With X and Y symmetry on, add any missing prongs manually — dropping to 0.5 mm diameter for the inner ones if needed — until every gem is held, and confirm.

12. Create cutters and cut the shank with boolean difference

Run Cutters on all the gems with the fourth preset. Then, in the Solid tab, Boolean Difference cuts the shank: select shank and prongs first, Enter, then the cutters, Enter again. Hide the gems to verify the cut came out clean.

13. Prepare the model for rendering

In the Rendering tab, use Lying on the Ground: select the whole model and press Enter. The ring lands in a natural resting pose, ready for your render.

Tips for a clean result

• Don’t skip O-Snap when extracting ISO curves — accurate snapping is what keeps the gem rows straight.
• Confirm your symmetry settings before placing each row to avoid misalignment.
• In the Boolean Difference, order matters: shank and prongs first, then the cutters.
• After creating cutters, hide the gems to visually verify the cut before proceeding.
• Keep the ISO curves on their own layer so they stay visible as placement references.
• Turn symmetry on early — one placed gem becomes two or four, and the rows stay consistent.
