Loading of Editable Appraisers
Appraisers are loaded during program startup according to the instructions specified in PacorBat.ini. Each appraiser is loaded using the LoadExternalGrading command which admits the modifier flags /edit, /profile, and /parents with the following meaning:
| Flag | Parameters | Description |
|---|---|---|
| /file | filename | Appraiser from <filename> is loaded as read-only. |
| /edit | filename | Appraiser from <filename> is loaded as editable. |
| /profile | filename | Profiles are read from <filename>. |
| /parents | filename1[;filename2...] | Specifies parent files which this appraiser depends upon. If the parent files are edited, then this appraiser is also considered updated. |
| /editsource | filename | <filename> is used as a default source of parameters. |
Path to the file can be specified either as absolute or relative to the batch file. Standard path specification variables like %ProgramData% can be used too.
A simple loading command may look as follows (here LocalAppraiser.txt is the appraiser file, and LocalAppraiser.pro contains its profiles):
LoadExternalGrading /edit LocalAppraiser.txt /profile LocalAppraiser.pro
One file may contain one or more appraisers. All editable appraisers would be available for selection on the panels Appraiser Interval Editor and Appraiser Profiles. Currently the editor deals only with the interval border values. If the appraiser contains no editable entities, it would not be seen in the list. When an appraiser is edited and saved, its file is reloaded, as are all files (if any) for which this one was specified as parent.
Switching of active appraiser in the editor does not entail switching of active appraiser in the optimization module.
Intervals Editing
All editable intervals are classified into cut parameters and symmetry parameters based on their name prefix: names starting with Restriction_ denote cut parameters, and those starting with Variation_ are considered symmetry parameters. Cut parameters may have arbitrary values. Symmetry parameters always have left border 0, which is not specified in the file and not available for editing.
For example, here is a description of the table width parameter:
interval : Restriction_Table : DC_TableDiameter : : : EX 55 59 VG 54 60.5 GD 53 62.5 FR 52.5 64.5 : (%) : "Intervals for Table"
When viewed in editor, it is represented as follows:
The purpose of global editor buttons is described below.
| Button | Function | |
|---|---|---|
 | Show/Hide Appraiser | Toggles the appraiser selection dropdown list. |
 | Show/Hide Parameters | Toggles the table of parameters. |
 | Show/Hide Intervals | Toggles the visual representation of intervals in the bottom of the window (it can be used for editing as well). |
 | Show/Hide Info | Toggles the display of overall parameter info: Grid, Minimum, and Maximum.
|
 | View cut | Switches to the list of cut parameters. |
 | View Symmetry | Switches to the list of symmetry parameters. |
 | Undo | Undoes the most recent change, if any. |
 | Redo | Redoes the most recently undone change, if any. |
 | Revert to file | Reverts the selected parameters to the values in the file. |
 | Revert to original | Reverts the selected parameters to the values in the profile. |
To edit an interval:
- Select the appraiser from a dropdown list, then select a profile on the Appraiser profile panel. The appraiser should be specified as editable in the file and also loaded as editable (see the syntax of the LoadExternalGrading command above), otherwise the editor is rendered view-only.
- (Optionally) Click Link profile and appraiser, so that all changes are applied to the profile and to the appraiser simultaneously.
- Select the cutting type. Note that the list of cutting types contain a special position called Common parameters. These are parameters applicable to all cuts. Specific cuts may redefine the parameters defined in it.
- Switch to cut parameters or symmetry parameters, depending on your purpose.
Below are the details of the interface dealing with the individual border values.
Double-clicking in any cell of the editable profile transforms it into an input field. Selection can be moved around using Tab / Shift+Tab keys.
You may change the field by typing the values in, or by dragging the intervals in the bottom of the window.
Pressing Esc finishes the editing and discards changes. Pressing Enter or clicking in another cell finishes the editing and keeps the newly entered value in the edited cell.
If the entered value collides with another interval border on the same side (no matter more strict or more loose), when editing is finished, that border is changed to the same value as the edited one, so as to maintain consistency. Such a change is considered single from the point of view of Undo/Redo, i.e., Undo would revert both borders at once to their corresponding previous values.
If the entered value collides with the opposite border, when editing is finished, the value of the edited border is set to the value of the opposite border, rather than the actual entered value.
If the appraiser definition file happens to contain inconsistent intervals, these are shown in red upon opening.
Changed values are shown in bold. The presence of unsaved changes is further indicated by the blue bullet in the name column of the corresponding line and the bold Save button at the upper right corner of the panel.
To save the changes, click Save. There are three equivalent Save buttons: on the Appraiser interval editor panel, on the Appraiser Profile panel, and on the Appraiser tab of the main application window.
Recalculation of Optimization Forms
For correct working of the optimization routine, the optimization forms must be recalculated (rebuilt) after the change of intervals. Being a time-consuming operation, it is not initiated automatically, and has to be started manually by clicking Recalculate cutting , or Recalculate all cuttings (if more than one cutting type were changed).
Creation and Editing of Profiles
An appraiser may contain multiple profiles. A profile contains interval borders for all cutting types, as well as the starting and optimization forms. It is impossible to have profiles with different cuts, or with different methods of grading of the same cuts. The profiles may differ only in the interval borders and the sets of forms.
All profiles are listed on the Appraiser Profile panel.
Top of the panel contains the functional buttons for manipulating profiles. The same buttons also appear on the Appraiser tab of the main application window.
| Button | Function | |
|---|---|---|
| New Profile | Creates a new profile with the data from the editor. | |
| New copy of Profile | Creates a copy of current profile. | |
| Delete Profile | Deletes the selected profile. | |
| Copy data to Appraiser | Copies data from the profile to the editor. | |
| Copy data to Profile | Copies data from the editor to the profile. | |
| Set to defaults | Sets the data to defaults. | |
| Link Profile and Appraiser | Link the profile to appraiser editor, so that any changes made in the latter are instantly copied to the former. | |
Profile name should be unique within one appraiser.
When a new profile is created, copies of all starting and optimization forms of the current appraiser are made. They are stored in the same folder as the original appraiser forms, and distinguished by a filename suffix sXXXX.
To edit the profile, copy the data from it to the editor, alter them, and then copy the data back. Alternatively, check Link profile and Appraiser so that all changes from the editor instantly appear in the profile. The edited profile gets saved upon pressing Save or upon switching to another profile.
Some predefined profiles are made read-only.
Application 1. Creating New Cut
Earlier appraisers contained just a single list of intervals, a list of optimization parameters, the start form, and the optimization forms. Modern format of editable appraiser (Version=7) is more complex and agile. For an appraiser to work, one has to specify the following:
- Parameters which are supposed to be graded.
- Grades for these parameters (editable or read-only intervals).
- Overall grade rules (a set of possible values for individual parameters' grades).
- Individual grades to appear in the diamond panel.
- List of parameters to use in the optimization.
- Intervals of parameter values to use in the optimization.
- Starting form and optimization forms.
As an example, let's create a new cut starting from the internal cut "Princess 3s". The previous appraiser contained the following description of this cut:

Graded Parameters
The graded parameters are those listed in the line Parameters.
Grading of Parameters
To grade the selected parameters, let us create a set of editable intervals of cut parameters.

Overall Stone Grading
Conventionally, the overall grade is composed of all cut grades (Restriction_*) and symmetry grades. Since we have not definedМ any symmetry parameters, there are only cut grades. To begin with, let us assemble them all into one composite grade called Restrictions:
grading : Restrictions : Restriction_CornerBreakAngle Restriction_TotalHeight Restriction_CrownAngle Restriction_GirdleBezel \ Restriction_CrownAngle2 Restriction_CrownHeight Restriction_PavilionDepthBezel Restriction_PavilionAngle1 Restriction_Table \ Restriction_VirtualCuletX Restriction_VirtualCuletY Restriction_GirdleRatio Restriction_CrownCleanLevel1 Restriction_PavilionCleanLevel1 \ Restriction_PavilionCleanLevel2 : Bad :
Now let us create a final grade consisting or Restrictions alone:
grading : Main : Restrictions : Bad : Final
Individual Grading of Parameters
To display the individual parameter grades in the diamond panel, we have to define a list called IndividualList and set up the correspondence between parameters and their intervals.
intervallist : IndividualList : name id : \ Restriction_CornerBreakAngle, DC_CornerBreakAngle; \ Restriction_TotalHeight, DC_TotalHeight; \ Restriction_CrownAngle, DC_CrownAngle; \ Restriction_GirdleBezel, DC_GirdleThickness; \ Restriction_CrownAngle2, DC_CrownAngleLevel2; \ Restriction_CrownHeight, DC_CrownHeight; \ Restriction_PavilionDepthBezel, DC_PavilionDepthBezel; \ Restriction_PavilionAngle1, DC_PavilionAngleLevel1; \ Restriction_Table, DC_TableDiameter; \ Restriction_VirtualCuletX, DC_VirtualCuletOffsetX; \ Restriction_VirtualCuletY, DC_VirtualCuletOffsetY; \ Restriction_GirdleRatio, DC_GirdleRatio; \ Restriction_CrownCleanLevel1, DC_CrownCleanLevel1; \ Restriction_PavilionCleanLevel1, DC_PavilionCleanLevel1; \ Restriction_PavilionCleanLevel2, DC_PavilionCleanLevel2; \ : "List for individual grading of parameters in Panel"
Optimization Parameters
The optimization parameters must be mentioned in the list called Optimize.

Optimization Intervals
To set up the intervals for optimization parameters, we define a set of optimization intervals. These intervals must be named opt_*.
optimizationinterval : opt_ca : DC_CornerBreakAngle : : Restriction_CornerBreakAngle : left : right : , : (°) : "Optimization for Corner Break Angle" optimizationinterval : opt_th : DC_TotalHeight : : Restriction_TotalHeight : left : right : , : (%) : "Optimization for Total Height" optimizationinterval : opt_b : DC_CrownAngle_Table : : Restriction_CrownAngle : left : right : , : (°) : "Optimization for Crown Angle" optimizationinterval : opt_gi : DC_GirdleThicknessBezel : : Restriction_GirdleBezel : left : right : , : (%) : "Optimization for Girdle Thickness" optimizationinterval : opt_b2 : DC_CrownAngleLevel2 : : Restriction_CrownAngle2 : left : right : , : (°) : "Optimization for Crown Angle Level 2" optimizationinterval : opt_hc : DC_CrownHeight_CrownAngle_Fixed : : Restriction_CrownHeight : left : right : , : (%) : "Optimization for Crown Height" optimizationinterval : opt_pdb : DC_PavilionDepthBezel : : Restriction_PavilionDepthBezel : left : right : , : (%) : "Optimization for Pavilion Depth" optimizationinterval : opt_a1 : DC_PavilionAngleLevel1 : : Restriction_PavilionAngle1 : left : right : , : (°) : "Optimization for Pavilion Angle Level 1" optimizationinterval : opt_t : DC_TableDiameter : : Restriction_Table : left : right : , : (%) : "Optimization for Table" optimizationinterval : opt_vcx : DC_VirtualCuletOffsetX : : Restriction_VirtualCuletX : left : right : , : (°) : "Optimization for Virtual Culet X" optimizationinterval : opt_vcy : DC_VirtualCuletOffsetY : : Restriction_VirtualCuletY : left : right : , : (°) : "Optimization for Virtual Culet Y" optimizationinterval : opt_rt : DC_GirdleRatio : : Restriction_GirdleRatio : left : right : , : (.) : "Optimization for Girdle Ratio" optimizationinterval : opt_c1 : DC_CrownCleanLevel1 : : Restriction_CrownCleanLevel1 : left : right : , : (%) : "Optimization for Crown Clean Level 1" optimizationinterval : opt_p1 : DC_PavilionCleanLevel1 : : Restriction_PavilionCleanLevel1 : left : right : , : (%) : "Optimization for Pavilion Clean Level 1" optimizationinterval : opt_p2 : DC_PavilionCleanLevel2 : : Restriction_PavilionCleanLevel2 : left : right : , : (%) : "Optimization for Pavilion Clean Level 2"
Start Form and Optimization Forms
Since the appraiser is editable, once the intervals are changed, the optimization forms might fall out of the corresponding groups, which would lower the algorithm performance. If the starting form would fall out of the group too, it would render the optimization inoperable. The forms should be listed in the file so as to make them capable of automatic recalculation:
form : "Start and optimization" : Start "DMCs\Princess 3s_Start.dmc"; \ SetDiamond1 EX DMCs\Princess_3s_EX_Set1.dmcx, VG DMCs\Princess_3s_VG_Set1.dmcx, GD DMCs\Princess_3s_GD_Set1.dmcx, FR DMCs\Princess_3s_FR_Set1.dmcx; \ SetDiamond2 EX DMCs\Princess_3s_EX_Set2.dmcx, VG DMCs\Princess_3s_VG_Set2.dmcx, GD DMCs\Princess_3s_GD_Set2.dmcx, FR DMCs\Princess_3s_FR_Set2.dmcx \ : allacceptable : auto : Type1 : "Standard 10 optimization min-max forms for all grades"
Sometimes automatic recalculation is impossible. For example, the appraiser 15Sep2016 uses non-interval Facetware grades for cutting type BrilliantF64. When working with such appraisers, the automatic recalculation should be turned off by changing "... : auto : ..." to "... : fixed : ...". After being edited, the forms (*.dmc and *.dmcx files) should be recalculated manually. Currently the appraiser editor offers no interface for this. If the forms falls out of the group, the appraiser would raise a warning in the terminal, telling that a certain form is out of the group and would be ignored in the calculation.
Conclusion
The above example was one of direct transfer of the data from the old appraiser to the new one, without any changes on along the way. There are the ways to get more creative. For example, culet offset is rather a Variation parameter than Restriction (since its lower border is 0):
interval : Variation_VirtualCuletX : DC_VirtualCuletOffsetX : : : EX 0 1.0 VG 0 1.02 GD 0 1.04 FR 0 1.09 : (°) : "Intervals for Virtual Culet X"
The optimization interval for a Variation parameter is defined as follows:
optimizationinterval : opt_vcx : DC_VirtualCuletOffsetX : : Variation_VirtualCuletX : -right : right : , : (°) : "Optimization for Virtual Culet X"
Then the parameter should be incorporated into the Symmetry composite grade, which in turn goes into the overall grade, together with Restrictions.
The list of individual grades should be updated accordingly.
Since this cutting makes no distinction between DC_VirtualCuletOffsetX and DC_VirtualCuletOffsetY, it would suffice to create just one interval for both. Call it some neutral name, like Variation_VirtualCulet. Grades still can be done independently for both parameters. Such practices are specific for each appraiser and cutting type. For example, culet offsets in X and Y directions are equivalent in Round brilliant (in that they use the same interval), but probably not in Emerald.
