GirdleShape1stDerEveryToleranceModule
Both Recut and SmartRecut solutions for the shapes different from Round Brilliant and Oval have a vertical girdle. Each girdle facet has its Azimuth,°. Because of the girdle verticality, the angle between neighboring facets equals to the difference between their Azimuth,°. The parameter defines that angles between two neighboring facets in Recut and SmartRecut solutions should not differ more than the parameter specifies.
Calculation
The parameter is set manually via preset and should be:
GirdleShape1stDerEveryToleranceModule / 100 * 360 / number of girdle facets > | | ( Azimuth X-REC,° - Azimuth Y-REC,° ) | - | ( Azimuth X-SR,° - Azimuth Y-SR,° ) | |
Where
- X, Y - two neighboring facets of the girdle in Recut (REC) and the same facets in further SmartRecut (SR) solutions
- Azimuth ... - their Azimuths
- 360 / number of girdle facets - average girdle angle for a particular cutting
- GirdleShape1stDerEveryToleranceModule / 100 * 360 / number of girdle facets - expression means that number that you specify in the system is:
- "how many % from the average girdle angle the SmartRecut may deviate from Recut" regarding angles described above
Usage and Examples
For a detailed description of how the parameter can be used for getting optimal solutions, see Using Girdle Shape Parameters page.

GirdleShape2ndDerEveryToleranceModule
Both Recut and SmartRecut solutions for the shapes different from Round Brilliant and Oval have a vertical girdle. Each girdle facet has its Azimuth,°. Because of the girdle verticality, the angle between neighboring facets equals to the difference between their Azimuth,°. There are differences between neighboring angles in Recut and in SmartRecut. The distinction between them should not be more than the parameter specifies.
Calculation
The parameter is set manually via preset and should be:
GirdleShape2ndDerEveryToleranceModule / 100 * 360 / number of girdle facets > | ( | | ( Azimuth X-REC,° - Azimuth Y-REC,° ) | - | ( Azimuth Y-REC,° - Azimuth Z-REC,° ) | | ) - ( | | ( Azimuth X-SR,° - Azimuth Y-SR,° ) | - | ( Azimuth Y-SR,° - Azimuth Z-SR,° ) | | ) |
Where
- X, Y, Z - three facets and X, Z are the neighbors of Y of the girdle in Recut (REC) and the same facets in further SmartRecut (SR) solutions
- Azimuth ... - their Azimuths
- 360 / number of girdle facets - average girdle angle for a particular cutting
- GirdleShape1stDerEveryToleranceModule / 100 * 360 / number of girdle facets - expression means that number that you specify in the system is:
- "how many % from the average girdle angle the SmartRecut may deviate from Recut" regarding angle difference described above
