Step-by-step guide

1. How to change interval for existed in appraiser parameter.

For example, user needs to change interval for Crown Angle for VG group to 30...36. It is necessary to

    2. Find section with "intervals" - it contains intervals for different parameters for different cut quality groups. Here user can edit intervals for EX, VG and other cut quality groups.

    3. Edit string:

      Before: 

      interval : Restriction_CrownAngle : b : : : EX 33 35 VG 10 90 GD 10 90 FR 10 90 : (°) : "Intervals for Crown Angle"

      After:

      interval : Restriction_CrownAngle : b : : : EX 33 35 VG 30 36 GD 10 90 FR 10 90 : (°) : "Intervals for Crown Angle"

    5. Find parameter DC_CrownAngle_Table - it is Crown Angle. In section Mass: and following table there are optimizartion intervals for parameters mentioned in Parameters: section. Each string corresponds to each cut quality group. All groupd are metnions in Quality: section.
    6. So we find second string for VG group and change 3rd and 4th values (they are correspond to Crown angle range) to 29.95 and 36.05 (we have to make 0.05 gap for optimization values in comparison with apprising values - it helps find better solutions during optimization):

2. How to add parameter and its interval to appraiser.


For example, user needs to add Total Heigth parameter with range 58...62.5 to EX group. It is necessary to

    3. Find section with "intervals" and add interval for EX group 58...62.5 like this:

      interval : Restriction_Table : t : : : EX 55 58 VG 10 99 GD 10 99 FR 10 99 : (%) : "Intervals for Table"
      interval : Restriction_TotalHeight : td : : : EX 58 62.5 VG 10 99 GD 10 90 FR 10 90 : (%) : "Intervals for Total height"
      interval : Restriction_CrownAngle : b : : : EX 33 35 VG 10 90 GD 10 90 FR 10 90 : (°) : "Intervals for Crown Angle"
      interval : Restriction_PavilionAngle : a : : : EX 40.6 41.0 VG 10 90 GD 10 90 FR 10 90 : (°) : "Intervals for Pavilion Angle"
      interval : Restriction_Star : star : : : EX 45 50 VG 10 90 GD 10 90 FR 10 90 : (%) : "Intervals for Star / upper ratio"
      interval : Restriction_LowerLength : lower : : : EX 75 80 VG 50 99 GD 50 99 FR 50 99 : (%) : "Intervals for Lower length"
      interval : Restriction_GirdleBezel : gi : : : EX 2.8 3.8 VG 0 20 GD 0 20 FR 0 20 : (%) : "Intervals for gidle thickness (bezel)"
      interval : Restriction_CrownHeight : hc : : : EX 12.7 14.0 VG 5 40 GD 5 40 FR 5 40 : (%) : "Intervals for Crown Height"
      interval : Restriction_GirdleValue : h : : : EX 0.75 2.04 VG 0 20 GD 0 20 FR 0 20 : (%) : "Intervals for gidle thickness (value)"
      interval : Restriction_Culet : cu : : : EX 0 0.5 VG 0 20 GD 0 20 FR 0 20 : (%) : "Intervals for Culet"

      interval : Restriction_Sum_ACP_APP : sum_ap : : : EX -3.0 3.0 VG -9 20 GD -9 20 FR -9 20 : (°) : "Intervals for Sum ACP APP"

    4. Find section grading : Restrictions and add Restriction_TotalHeight there: 

      grading : Restrictions : Restriction_Table Restriction_TotalHeight Restriction_CrownAngle Restriction_PavilionAngle Restriction_Star Restriction_LowerLength Restriction_GirdleBezel Restriction_CrownHeight Restriction_GirdleValue Restriction_Culet : Bad :

    5. That is all. There is no need to add parameter TotalHeight in optimization part My GIA 4 because there are other parameters which form total height of stone and they are optimized.
