STL 3D Reverse Engineer in Rhino supplying 3Dm file

Require a RHINO 3DM File that is fully editable. Retrofit must be constructed over the top of the original STL file, which should be a left as layer in the 3dM file for comparison.

1. The Tiara should constructed in separate 5 layers + the star as shown in attached file.

2. Layer 1,2,3,4 should be 0.2mm, Layer 5 should be 0.3mm and all built and kept as separate layers for future editing of shape and layer depth in rhino

3. Part 3a should continue the width of 3. Detail has been lost in STL scan. Please retrofit to photo.

4. Extend parts 2/1/3a by approx. 2 cms as in photo above (included in further pages) and match end curves of 3/3/5 by ear.

5. Add curve to 2a.
