Advanced Bezel

Advanced Bezel

The Advanced Bezel command is the free-form version of Bezel. The base command builds the bezel wall from a fixed set of numbers — width, height, over girdle height, girdle — while Advanced Bezel lets you draw the section of the wall yourself, point by point, directly in the viewport against the silhouette of the stone. Everything else — post supports, cutters and airgaps — is still there, plus the construction and measuring options a production file needs.

Run the command and select one or more gemstones. Each selected gem gets its own bezel, all sharing the same parameters. Unlike the base command, Advanced Bezel opens straight into the parameters: there is no gallery to go through first.

The panel is organized as three tabs inside the Parameters section: Profile, Cutters and Airgaps.

Profile

This is the heart of the command. Instead of numeric fields for the wall, RhinoArtisan draws a cross-section of the bezel in the viewport — the wall profile as a thick accent polyline, together with the silhouette of the stone cut by the same plane — and you shape the wall by dragging the numbered points of that profile.

The panel keeps the list of those points in sync: each row shows a numbered badge matching the numbered dot in the viewport.

• Profile Points: the list of points of the wall section. Point 1 is the anchor on the gem outline and cannot be deleted; a profile always keeps at least three points.
• Add Point: click the add button and then click on the profile polyline in the viewport. The new point is inserted into the segment you clicked, and the rest of the profile stays exactly where it is.
• Sharp / smooth corner: each point row has a break toggle. A sharp point makes a corner; a smooth point lets the wall pass through it as a curve — the same idea as the break points of the asset editor.
• Delete: removes a point from the profile.
• Undo: steps back through your last profile changes (dragging, adding, deleting, toggling a corner).
• Radius: fillets the sharp corners of the profile. 0 keeps them sharp.

Dragging a point only moves that point: the offsets of the following points are compensated automatically, so the rest of the section does not travel with it.

Post Support

• Post Support: adds from 1 to 6 supports for an earring post, or None.
• Width and Thickness: the dimensions of those supports.

Advanced

• Bezel mode: how the wall is built on the rounded gem shapes — Automatic (the per-shape default, matching the classic Bezel command), Sweep or Rail revolve. In Rail revolve a draggable handle appears on the gem plane together with a dashed line showing the revolve axis: move it to shift the axis away from the gem centre and open up asymmetric walls. The special multi-segment shapes (Marquise, Heart, Trillion, Triangle, Calf, Coffin) keep their own construction and ignore this option.
• Section plane: where the editing section is taken — Perpendicular to the girdle curve, or forced to the gem’s ZX or ZY plane.
• Position (%): moves the editing section along the outline of the stone, from 0 % at the gem’s +X side. On fancy shapes this lets you check the same profile at the point, at the side and at the shoulder.

The section plane and its position only change what you see and edit in the viewport; the solid is not affected.

Viewport helpers

• Bounding box: draws the bounding box of the section with its X and Y sizes, as proper dimensions.
• Sharp point distances: dimensions the straight distances between consecutive sharp points around the profile — the measurements you would hand to the bench.
• Hide elements: hides the stones and the bezel preview so the section and its dimensions read on their own.

Cutters

The Cutters tab cuts openings through the bezel wall.

• Quick buttons place None, 4, 6 or a custom number of cutters.
• Section Curve: the closed profile used as the cutting shape, taken from your assets and editable there.
• Number of cutters, Width and Height: how many cuts and how big.
• Move in vertical: raises or lowers the cutters along the wall.
• Rotation and Vertical rotation: turn each cutter on itself and tilt it.
• Global rotation: turns the whole ring of cutters around the stone.

Airgaps

The Airgaps tab works exactly the same way, with its own profile and its own set of parameters — quick buttons for None, 4, 6 or a custom number, Number of airgaps, Width, Height, Move in vertical, Rotation, Vertical rotation and Global rotation. Airgaps lighten the piece and open the underside of the setting so the stone breathes and light gets in.

Presets and defaults

The header of the panel lets you Save the bezel you have designed into the gallery, so it can be reused on other stones, and Save defaults to make the current configuration your starting point for the next run; right-click the same button to delete the saved defaults and go back to the factory values.
