Calculation

-------------------

For Round Brilliant, Oval:

SweetLine,° = PavilionAngle,° - PavilionAngle,° (OL)

Where:

• PavilionAngle,° - Avg (average) value for the model is used
• PavilionAngle,° (OL) is PavilionAngle,° of the point on the SweetLine Axis, that has the same CrownAngle,°
• CrownAngle,° - Avg (average) value for the model is used
• SweetLine Axis is the line with negative slope 1:6 passing through the point with CrownAngle = 34.5 and PavilionAngle = 40.75

• Negative slope 1:6 means "each 6° increase of CrownAnge is 1° decrease of PavilionAngle

-------------------

For AnyCut:

As there are multi-tier cuts, their angles are all different and the angles of some specific facets do not matter, therefore in the SweetLine calculation, the CrownHeght and PavilionHeigth are used.
