Quick Start: Interactive Slicer

This quick start focuses on learning the Interactive Slicer by walking through the first pavilion tier, girdle, crown, and table. Keep the studio open in another tab so you can follow along.

Tip: The studio autosaves in your browser. Close the tab and come back later—your last design reopens automatically.

1. Open the studio and click New

Launching the studio drops you into the 3D stage. By default, the Interactive Slicer tab is active below the viewer (or to the side on large screens).

To see the code, switch to the Spec Editor tab. Hit New to load the blank template:

name = "Untitled Design"
ri = 1.54
gear = 96

This is the starting "rough" we’ll carve away.

2. Set up the first pavilion tier

Switch back to the Interactive Slicer tab if needed:

  1. Choose Pavilion for the side (we normally begin on the pavilion).
  2. Set Symmetry to 8.
  3. Enter Angle 37.50° and Base Index 0.
  4. Pick Center Point (cp()) as the target.

The slicing plane animates into view. Hovering over the Preview button displays the cut.

3. Commit the cut

Press Commit to apply the tier. The viewer redraws with the new facets. (You can verify the generated code in the Spec Editor tab):

name = "Untitled Design"
ri = 1.54
gear = 96

P1 0 @ 37.50 : cp() x8

Rotate the viewer and you’ll see the pavilion facets meeting at the center. More steps will follow, but getting comfortable with this rhythm—choose parameters, preview, commit—is the foundation for building complete stones.

4. Establish the girdle depth

Next, set up the girdle ring:

  1. Keep Side on Down, but change the Angle to 90.00°.
  2. Switch the target to Depth and enter 1.00 for the value.
  3. Leave symmetry at 8 and base index at 0, then click Commit again.
name = "Untitled Design"
ri = 1.54
gear = 96

P1 0 @ 37.50 : cp() x8
G1 0 @ 90.00 : 1.0000

You now have the pavilion facets and the girdle defined—a solid foundation before working through additional tiers.

5. Cut the first crown tier

Now flip to the crown side:

  1. Change Side to Crown.
  2. Set Angle 25.00°, Symmetry 8, and keep Base Index 0.
  3. Pick Proper Meetpoint as the target. The slicer will highlight multiple nodes—click the meetpoint where the girdle and pavilion facets touch.
  4. Check Girdle Offset so the cut keeps the girdle at the right thickness.
  5. Hit Commit to apply the crown tier.
name = "Untitled Design"
ri = 1.54
gear = 96

P1 0 @ 37.50 : cp() x8
G1 0 @ 90.00 : 1.000
C1 0 @ 25.00 : mp(P1, G1) + girdle

At this point, the pavilion, girdle, and first crown tier are in place.

6. Add the table

Finish the crown by cutting the table:

  1. Keep Side on Crown but change the Angle to 0.00°.
  2. Select Depth as the target and drag the slider (or type) to your preferred table height.
  3. Set Symmetry to 1 (tables are usually single facets).
  4. Press Commit to flatten the top.
name = "Untitled Design"
ri = 1.54
gear = 96
size = 2.0
girdle = Vector(0, 0, 0.03)

P1 0 @ 37.50 : cp() x8
G1 0 @ 90.00 : 1.000
C1 0 @ 25.00 : mp(P1, G1) + girdle
T 0 @ 0.00 : 0.0900 x1

You now have a basic pavilion, girdle, crown, and table—enough to explore the diagram (printable instructions) or continue refining each tier.

What’s next?

  • Open the Diagrams panel to generate printable SVGs once you finish a few tiers.
  • Explore the Interactive Slicer guide in Tooling → Interactive Slicer for advanced targets and meetpoints.
