Diamonds and Gemstones
CPlane on Gem
CPlane on Gem
The CPlane on Gem command aligns the active viewport’s construction plane to the plane of a selected gem.
Select a single diamond or gemstone. The command reads the gem’s own plane and sets it as the construction plane of the active view, so the CPlane’s origin sits at the gem and its axes follow the gem’s orientation. The command line reports the coordinates the CPlane was aligned to.
This is a quick way to start sketching or snapping relative to a specific stone — for example, drawing a prong or seat profile flat against the gem’s own plane instead of the world CPlane.
