Peghead

Peghead

This command allows you to set a selected gem into a Peghead configuration.

Running this command will display its parameters in the Commands toolbar. Your first step is to select the stone on which the Peg Head will be applied. Next, decide whether to start with a pre-designed style from the Peg Head gallery provided by RhinoArtisan or to modify the current style displayed in the viewport. To create a new design based on the current style, simply click the “Edit” button.

Once you edit the one you have selected or the one in the viewport, the parameters will be shown in the Command Panel:

• Number of prongs / orientation: an image selector for how many prongs the peg head has. The options depend on the shape of the selected gem — for round gems, for example, you can choose 3, 4, a 4-prong layout rotated 45° (reverse 4), or 6 prongs.
• Profile: a preview of the prong’s cross-section shape, with buttons to select a different profile from RhinoArtisan’s asset library or edit the current one.
• Thickness: the thickness of the prongs.
• Height over Girdle: how far the prongs rise above the gem’s girdle.
• Height: the total height of the peg head.
• Girdle Width: the width of the prongs where they meet the girdle.
• Gem Inside: the overlap distance of the prong tip inside the gem (a negative value moves it outward instead).

You can also save the current parameters as your defaults, or save the edited peg head as a new style in the gallery, from the header toolbar.
