Rhino command: JewelSnap

If a the base geometry changes a little bit the crystal components can be snapped back to the surface to ensure the right height according to the surface. This is only suitable if the changes are very small, because the new position will be calculated as a perpendicular projection to the surface. This means, if the geometry is too far away, the component will be placed somewhere on the geometry and the overall picture of the jewel setting will be lost. In this case the components should be positioned near the new geometry with the Rhino translation function.
