SAMIHA HALF-RING DRAWINGS — RHINO 7 / MATRIXGOLD HANDOFF

Files
  Samiha_A_Inward_Half_Editable_Rhino7.3dm
    All six smaller leaf pairs face inward. Their connected cut profile has
    smaller, tighter diamond openings.
  Samiha_B_Alternating_Half_Editable_Rhino7.3dm
    Alternate smaller pairs reverse direction. The cut profile has larger,
    more open diamond shapes.
  Each variant has a monochrome half line drawing (black cut profiles, gray
  editable guides), a cut-profile-only view, and full mirrored previews.
  The full previews rotate a copy of the half by 180 degrees for comparison;
  they are not extra client CAD geometry.

Both files are 2D HALF drawings in millimeters, saved in Rhino 7 format.
They are not meshes, 3D solids, or MatrixGold parametric-history files.
The numbered 01_CUT_PROFILES_USE_THESE layer contains eight closed native
NURBS curves: one outside boundary and seven opening boundaries. Use these
as the authoritative 2D profiles for the client's MatrixGold workflow.
The hidden 02_EDITABLE_LEAF_GUIDES layer retains seventeen editable cubic
NURBS/polycurves for local changes to the frame and individual leaves.
After changing guide curves, rebuild or edit the cut profiles accordingly;
the guides alone do not update the cut profile automatically.

Open one file in Rhino 7/MatrixGold. Keep only the cut-profile layer visible
for contour operations. The client can duplicate and rotate the half in the
usual workflow, then perform the 3D operations and any final metal/gemstone
decisions there. No 3D result or manufacturing thickness is specified here.

Checks: both files were reopened with rhino3dm; all 25 objects in each are
valid closed curves, the cut profiles define a single connected metal area,
and each file reports millimeter units and a Rhino 7 header. The NURBS cut
profiles follow the polished 2D contours within 0.061 mm. These checks do
not establish casting suitability, minimum wall thickness, or exact visual
parity with the low-resolution source photos/video. Those need inspection in
the client's Rhino/MatrixGold environment before fabrication.

The gold product image was generated from the full mirrored line previews
and the genuine client photo and video frame.
It is an imaginative presentation image, not a reference, dimensioned
design, or approved 3D render.
