Integration with Cutwise
View solutions in 3D interactive space
Cutwise online service integrated with HP Carbon allows quick sharing via the Internet information about polishing plans (solutions), including renderings of future stones, indistinguishable from the real DiBox2 films for both Round and Fancy cuttings. Now in addition to visual and parametric representation of plans, Cutwise is able to present solutions in 3D interactive space (like Scene in HP Carbon) - Carbon Viewer.
Thus, full information about plans ( parameters + media + interactive 3d model ) now can be easily shared with the remote team members (polishing experts, managers, sales specialists) or customers. The Carbon Viewer provides full and interactive information about:
- number, size, and position of inclusions
- how diamond(s) is positioned relatively to rough and inclusions; if several diamonds in a plan - how they are positioned relative to each other
- distances between rough, diamonds, and inclusions

Smart Recut and Smart Normalize updates
SmartRecut: launch of SmartRecut in in-house cut workflow directly on SmartRecut solutions
Since HPC 1.5 it is possible to run SmartRecut in AnyCut workflow directly on SmartRecut solutions. In earlier versions this was available for RBC workflow.
After you have run "22. Single (Recut)" + SmartRecut and have chosen the best solution, you can run SmartRecut on this solution again with all presets or with your favorite one. As a result, you can get a solution with similar performance and more mass, or even a solution with better performance. The workflow is absolutely similar to classic SmartRecut: select the SmartRecut solution you want to increase and Run SmartRecut.
in AnyCut workflow SmartRecut parameters can be divided into three groups:- Parameters in the appraiser. They are absolute or relative to the allocation form. These parameters are the same in all presets. These parameters are the same for all SmartRecut runned on SmartRecut.
- Relative parameters in the presets. They are relative to the input solution. In SmartRecut runned on solution of algorithm "22. Single (Recut)" or similar, these parameters don't let the solution stray too far from the cut proportions. Due to them SmartRecut runned on SmartRecut increases the mass, because the input solution is changing. But at the same time, stray from the cut proportions increases.
- Absolute parameters in the presets. These parameters are different in different presets. If you are running SmartRecut with a narrow preset (eg 1.AllNarrowed) on the solution obtained by a wide preset (eg 8.AllWidened), then SmartRecut runned on SmartRecut may not work because the input solution is too asymmetric. Such launches are not prohibited. But for stable operation, we recommend you keeping or widing the preset during the SmartRecut on SmartRecut process.
On the picture below there are five solutions obtained by the preset "1.AllNarrower" and recolored in the colors of the rainbow. The algorithm was run one by one 1 → 5 → 6 → 7 → 8 → 9. As you can see, the price of the solution is growing, but the gain is decreasing each time
SmartNormalize batch-mode for registration of many (100 and more) allocation forms
To register Goodwin cuts allocation forms, you need to run SmartNormalize algorithm on every model. For hundreds of forms it takes a very long time and inevitable human errors. We have automated this process as much as possible.
1) Prepare models array for Cut registrations:
- Choose your cut pattern. We recommend registering models with different patterns in different cuts
Gather together .dmc files with models of the selected pattern. It could be scans or allocation forms of your old In-house cuts.
Specify Cut grade models in filenames if you have this information. Future allocation forms will have these names
2) Now you need to register yourself the first form
- Register cut using "Register as new cut...". You need not .dmc file for this. For example, .ox2z or .dmx file. For details see In-house cut registration
- Set parameters limits to Absolute Appraiser of your Cut. For details see Appraisers for specific in-house cuts
- Restart HP Carbon.
3) Then you can right-click on this Cut in Cutbook and choose "Batch add forms..."
4) Choose your .dmc files in pop-up Windows explorer and press ok. In order not to overload the computer memory and for ease of data recovery in case of any failures, we recommend running 100-500 models
5) You will see progress bar
Each selected .dmc file will be loaded into the program. The SmartNormalize algorithm with the preset "2.Medium_Sym_CFM" will be launched on the model from the file. If no significant errors are found in the SmartNormalize process, the solution will automatically register as an allocation form.
6) The following message will appear at the end.
In the Allocation solutions list, all models and BatchSmartNormalize solutions will be in № order
Here is the following useful information:
.dmc file name in "Alloc" column for loaded models
Tag "BN" and preset color in "Alloc" column for solutions
Grade by cut Absolute Appraiser
Errors in "Alloc" column tooltip
Color labels (details in next chapter)
SmartNormalize auto color labels
To simplify the choice among SmartNormalize solutions, the algorithm began to place Color labels that warn about the presence of known errors. In SmartNormalize batch mode color labels also determines if the allocation form has been registered automatically.

Good solution for registration. Automatically found warnings should not bad affect the work with this preform in the future. Possible Warnings:

...
Automatic registration.
If you like, you can review these solutions, write down their names, and remove them from the allocation forms.
...
...
It means Warning: "SmartNormalize found solution with perceptible volume difference to start model. Please, check result"
Volume difference is perceptible but not big. Most likely input model is rather asymmetric, but solution is good for registration. This situation need manual user check.
...
...
No automatic registration.
We recommend reviewing these solutions and most likely adding them manually to allocation forms. If you don't like the solution, you can run all SmartNormalize presets on these models and maybe get a green solution.
...
...
The solution contains errors, registration with which is not recommended....
...
No automatic registration.
Review these solutions and read errors in "Alloc" column tooltip. Try to get the green SmartNormalize solution by following the prompts in the error messages and running all the SmartNormalize presets. Or you can ignore these model.
...
Can not be in SmartNormalize without batch mode. First cut form is unknown.
...
...
No automatic registration.
It means Critical error: "SmartNormalize solution Facet Types is different from first preform Facet Types. Please, check result". Ignore these model. Most likely the .dmc file contains a model with a different pattern or with Extra Facets. We recommend registering models with different patterns in different cuts. In case of Extra Facets you can try to colorize the model Facet Types correct considering Extra Facets and running all the SmartNormalize presets. But remember that checking for violet label will no longer work without a batch and you yourself need to check the identity of the pattern.
SmartRecut errors log
Sometimes the SmartRecut algorithm does not find a solution, and it is not clear what to do next. In some of these situations, the algorithm can automatically determine the cause of the problem. We have developed an error logging system for SmartRecut, SmartNormalize (/ Lite), SmartZoom algorithms so that users can adjust their actions based on the received information. You can see error messages in two locations:
1) For SmartRecut, SmartNormalize, SmartNormalizeLite solutions errors can be viewed in the Alloc column tooltip
2) In the standard logger panel. To open it you need to press View → Show logger (info) panel.
These messages are related to Module SmartRecut.dll. Message always starts with the name of the related preset.
All messages can be divided into 4 groups:
1) Warning. Does not block the work, the algorithm gives some result. Tells the user some information and possibly instructions.
2) Error Messages containing "Please inform the developer". These are rare technical problems. The user cannot bypass them on his own.
3) Error Messages containing instructions for the user.
4) The rest of the error messages. There is no instruction in them. From the text of the message, you can sometimes understand what the problem is. For example, a specific cut does not interact correctly with the appraiser or reports.
Get plans for Brilliant cut that are safe from perspective of GIA cut grade
In HP Carbon, plans for Brilliant cut are allocated with the "GIA Facetware + My Round" appraiser. GIA Facetware rounds the parameters' values.
In some cases, this rounding may cause a problem: when you finish cutting in precise accordance with the plan and the result is scanned, different scanners (for example, yours and GIA lab) may slightly deviate the scanned model. So if our plan was too close to rounding boundaries, the resulting parameter value after rounding may go outside the EX boundaries to VG, etc. This can cause your EX stone from your scanner perspective will unexpectedly become VG from the GIA lab perspective.
To eliminate this risk, for the Smart Recut algorithm, the new Safe Boundaries mode is added. It is intended to be used when working with Brilliant cut. The mode sets safe distances to a possible GIA rounding. The values are:
...
| title | Example for Crown Angle |
|---|
...
...
...
| Note |
|---|
At the moment, these values cannot be changed - in the future, it is planned to provide a user interface for viewing/editing. |
The mode is turned on by the Safe Boundaries checkbox.
The mode can be used when running the Smart Recut allocation from Recut solution. However, if you already have a Smart Recut solution previously obtained without using the Safe Boundaries option, it is more effective to run Smart Recut allocation with Safe Boundaries from this previous Smart Recut.
| Note |
|---|
The Table parameter can obtain a value close to the GIA rounding boundary (for example, 58.49%). This means that regardless of rounding up or down (58% or 59%) the required GIA Cut Grade will be produced with the other 5 GRID parameters set. |
SmartRecut + Safe Boundaries upgrade
There are two errors when grading diamonds obtained from SmartRecut solutions by GIA. First — the scanned on different scanners model may slightly deviate. Second — GIA before rounding uses a peculiar way of parameters averaging instead of the usual mathematical averaging. But SmartRecut can only use usual mathematical averaging. In the previous version both errors was including in Safe Boundaries margin. Therefore, if we added the full margin to the solution Math values then it was ok. But if we added the full margin to the solution GIA values, then it was possible to go beyond the GIA Cut grade.
In the current version Safe Boundaries margin is responsible only for the possible scanner error. And SmartRecut separately takes into account GIA rounding error (dead zone). So you can add the full margin to the solution GIA values, it will be ok.
MyRound boundaries and GIA Cut grade conflict in SmartRecut
SmartRecut sometimes found solutions with bad GIA Cut Grade due to narrow MyRound boundaries on the parameters Table, CrownAngle, PavilionAngle, StarLength, LowerGirdleLength, GirdleBezel. This program behavior has been fixed. However, SmartRecut still cannot use the space close to the Boundaries between two 6D-cells ("dead zone"). If this happens then there is error message comes to Log:
To fix this problem please refer to the new documentation page Recommendations on Boundaries for main GIA parameters or open below description:
...
| title | Recommendations on Boundaries for main GIA parameters |

GIA Cut Grade Boundaries
GIA Cut Grade is used during Brilliant Cut optimization with appraiser "GIA Facetware + MyRound". This grade is a complex nonconvex discrete function from 6 parameters: Table, CrownAngle, PavilionAngle, StarLength, LowerGirdleLength, GirdleBezel. The characteristics of this function create problem to use it in optimization algorithms. SmartRecut operates in 2 stages. At the first stage, a solution is sought in a large convex area of the parameters six-dimensional space. Most of the area is of user-defined quality. But there are also parts of the area with less quality. If the optimal by weight solution gets less quality during optimization, then algorithm goes to second stage. At the second stage, the nearest six-dimensional cell of user-defined quality is found and optimization does not go beyond its Boundaries.
The first figure shows for each of the 6 parameters: Boundaries of cells, Size of cells, centers of cells — Rounded values for GIA grade and rounding of average values to Rounded values for GIA grade is illustrated. The values for the figure were taken closer to the center of the EX zone. Exception: There is no EX-combination with LowerGirdleLength = 65.
Another problem with the GIA Cut Grade for optimization algorithms is that the GIA before rounding uses a peculiar way of parameters averaging instead of the usual mathematical averaging. SmartRecut can only use standard mathematical averaging. Therefore, SmartRecut cannot use the space close to the Boundaries between two 6D-cells, let's call it a "dead zone" (below there is detailed description of "dead zone"). Otherwise, SmartRecut may get user-defined quality, but the GIA will rate the diamond with a less quality due to peculiar averaging.
In-house cut workflow improvements
Own presets with its own appraiser for in-house cuts
Now each in-house cut has its own presets along with its own appraiser. Advanced users can customize SmartRecut via presets based on the individual cuts characteristics
Compatibility of in-house cuts and linked appraisers between HP Carbon and Helium Rough/Pacor Client
Currently some allocation algorithms exists only in Helium Rough/Pacor Client but not in HP Carbon. Mainly there are semi-automatic or manual algorithms, that are available in Tools mode (like "Fixed Diamond Weight", "Change cut" and so on).
Therefore the same project is need to be open in both programs (HP Carbon and HR/PC) and compatibility of cuts and appraisers is required for work convenience.
Previously registered in HP Carbon Cuts and linked Appraisers are automatically loaded to Helium Rough since version 7.4 if Helium Rough is installed on the same computer.
Hybrid Appraisers (with Absolute and Relative parts) has limited compatibility:
- Helium Rough program version 7.4 doesn't have option to enable/disable Absolute and Relative parts.
- There is no convenient switch between profiles
Helium Rough will allocate with the same conditions of hybrid appraiser like they was during exit from HP Carbon. Under conditions we mean absolute, relative parts and profile .
Example of work:
Suppose we have following list of in-house cuts in HP Carbon:
When we run Helium Rough then the same cuts will be available in panel Diamond.
To run allocation with in-house cuts it is required:
- To create new list in Rough Classification panel and add necessary in-house cuts there.
- Select Intervals/Appraiser Auto.
Auto Appraiser allows to run allocation with several cuts and their linked different appraisers.
Usability upgrade of in-house cuts presets
To simplify navigation, the parameters in in-house cuts presets are sorted into groups with the addition of prefixes in the names: "Girdle_", "Angles_", "Distances_", "ExtraFacets_"
Integrated documentation is connected for all parameters of the "Girdle_" group.
If you need to reduce the Area Loss of the SmartRecut solution, then decrease the Girdle_PointsAxialSymmetryIdeality via presets and restart the optimization.
Some exceptions are described in the integrated documentation Girdle_PointsAxialSymmetryIdeality or under 
in program.
Аutomatic adjustment of appraiser intervals for in-house cut to set start allocation form to EX group
During in-house cut registration program creates appraiser with parameter intervals from the selected template. Start allocation form which is used for cur registration could be out of EX group by some parameters.
There is new feature in software to adjust automatically intervals "Absolute Proportions" to set start allocation form in EX group that is required for correct work of further allocation.
The intervals adjustment is following: intervals from templates are shifted on the some value of parameters ("parallel shift" for parameter intervals of EX, VG, GD, ... groups). The value of the shift is found by software by such way that value of each parameter is exactly in the middle of EX group. Therefore all values of start allocation form are set in the middle of EX group. Intervals size [min, max] for each group are remained the same as in template.
| Intervals before adjustment | Intervals after adjustment |

MyRound boundaries and GIA Cut grade conflict in SmartRecut
SmartRecut sometimes found solutions with bad GIA Cut Grade due to narrow MyRound boundaries on the parameters Table, CrownAngle, PavilionAngle, StarLength, LowerGirdleLength, GirdleBezel. This program behavior has been fixed. However, SmartRecut still cannot use the space close to the Boundaries between two 6D-cells ("dead zone").

SmartRecut Girdle control upgrade for in-house cuts
During SmartRecut AnyCut optimization, the Girdle_Shape1stDerToleranceModule and Girdle_PointsAxialSymmetryIdeality parameters can create contradictions. The first one tries to keep the girdle shape of the Recut solution. The second one tries to make the girdle perfectly symmetrical. If the Recut solution girdle is not perfectly symmetrical, then an unresolvable contradiction may result. This is mainly a consequence of user errors during cut registration. Examples of such errors are in Girdle_PointsAxialSymmetryIdeality
In this version, SmartRecut uses Facet Types to determine the symmetrical sectors of the girdle and averages the start girdle shape of the Recut solution over reliable symmetrical sectors. Due to this, the probability of an unresolvable contradiction is significantly reduced. And the correlation between the Girdle_PointsAxialSymmetryIdeality parameter and the AreaLoss value improves.
SmartNormalize automatically fixes simple errors in FacetTypes
To increase model symmetry and remove excess facets, you can use the Smart Normalize algorithm. Previously, if the model that you were going to normalize had mistakes in its facet types, Smart Normalize could provide non-symmetrical solutions. Now the algorithm is improved: it tries to fix mistakes in facet types and then provides excellent symmetry.
Hint This is especially useful when mistakes are not obvious to an operator.
Technical details:
- The algorithm tries to fix facet type mistakes using information about groups of symmetrical facets and which type dominates in a group. If the situation is clear enough, mistakes in facet types are fixed automatically and the algorithm finds the solution with the correct number of symmetry axes. If the case is too complex, the algorithm uses initial facet types without changes.
- Fixing does not change the initial model facet types but does change the resulting model - it will have different (fixed) facet types.
Example:
| Easy to see with the eyes | Not obvious to an operator | |
|---|---|---|
| Initial model |

| Normalized model |

Control absolute value azimuths for in-house cuts
In previous versions, for in-house cuts the algorithm 19. SmartRecut (Brilliant, Oval, AnyCut) controlled only the azimuths symmetry of the facets. But a change in the absolute value of azimuths could lead to a big loss of the solutions performance.
Therefore two parameters have been added to control the tolerance of azimuths from the initial values. More "narrow" MainAzimuthsToleranceModule is tuned for only Main facets. Less "narrow" OtherAzimuthsToleranceModule is tuned for other facets.
Precise fixation of parameters StarLength and LowerGirdleLength in SmartRecut (Brilliant)
StarLength and LowerGirdleLength are parameters that greatly affect the pattern of the stone, but practically do not affect the mass. Sometimes there is a need to get a specific average value for these parameters. Now you can do this by setting an interval of 0.02 length in MyRound. SmartRecut solutions will have the value exactly in the center of the interval. However, when setting narrow boundaries, it is necessary to take into account the dead zone, especially when working in Safe Boundaries mode. You can find out more information on the new documentation page Recommendations on Boundaries for main GIA parameters
Reports improvements
New report type - Rough Report
Objective
A manager receives a batch of stones, these each are in their own package. A Rough Report is printed in a small size and applied to a package with a stone.
The Rough Report is needed so that the manager can quickly check what was expected to do with the stone not opening its package.
Controlled diamonds' parameters: weight, cut quality, appraisers, Crown and Pavilion angles, etc.
Creation of Rough Report
- An operator sets the starting position of the stone in the HP Carbon scene for further an image generation.
The main scan or a solution could be rotated. Stone position in Rough Report is synchronized with the HP Carbon Scene.
- The operator selects the solution to be made in the Plans & Scans panel.
- The operator can select diamonds to be included into the report.
All diamonds are shown in Rough Report by default. Diamonds could be added or removed in opened report it will be updated in this case.
This is done using the context menu in the panel containing diamonds info for the current solution.
- Open Rough Report panel.
- Selection of a printer. The selected printer is saved in HP Carbon and will be shown at further openings of Rough Report.
- Print the Rough Report.
Rough Report features
The operator can change colors in Rough Report (Rough, Model, Saw, Inclusions). It will be updated at a color changing.
Also enhanced precision could be changed in the range [-3, 3] digits. The report will be updated at an enhanced precision changing.
All settings are saved in HP Carbon.
The Rough Report will be updated at selection of another solution.
Inclusions while aren't embedded in Rough Report images.
Illustrated HTML Report templates for many other cuts are available (besides RBC)
The convenient single-page reports in HTML format have been made for most types of cuts (as was previously done for RBC), so that the operator, without the need to use MS Word, could open the main parameters of the model on the screen on one page and transfer them to the clients/auditor/manager:
- Polished HTML Illustrated Report Step Cut;
- Polished HTML Illustrated Report Radiant;
- Polished HTML Illustrated Report Square Radiant;
- Polished HTML Illustrated Report Triangle;
- Polished HTML Illustrated Report Rounded Fancies;
- Polished HTML Illustrated Report Oval-Marquise.
These reports are located in "Polish Report..." for a specific type of cuts, for an example:
Examples of reports:
1) Illustrated HTML Report Step Cut 
2) Illustrated HTML Report Radiant
3) Illustrated HTML Report Square Radiant
4) Illustrated HTML Report Triangle
5) Illustrated HTML Report Rounded Fancies
6) Illustrated HTML Report Oval&Marquise
View grades for Cushion cuts in reports
For the Rectangular and Square Cushion cuts the grades were added to the following reports:

Algorithms of allocation
New algorithm "21. Next" for allocation
To add one more diamond to already created solution you can use algorithm "21. Next". The next diamond will be added in maximal possible free zone of rough volume which is not occupied by created before diamonds. A position of existing diamonds is not changed.
Important! Algorithm "21. Next" during work takes into account allocation forms of Cut that allows to find better solutions for in-house cuts. Note that algorithm Find Next Diamond in Helium Rough / Pacor Client doesn't work with many allocation forms so we recommend to use "21. Next" and HP Carbon to find next diamond.
Before run of algorithm please make sure that you select one or several solutions where you want to add one more diamond and cut types from Cutbook.
There is possible to create solutions composed of 2, 3, 4 and so so diamonds.
There is a sample of algorithm "21. Next" work:
0012_NextDiamond.ox2z
Sol. #40 contains 5 diamonds, it was allocated sequentially from sol. #24, 30, 34.
New algorithm "22. MESM for blocking"
We have implemented a new algorithm: Minimum Enclosing (Encompassing) Symmetrical Model - "22. MESM for blocking"
The algorithm finds the Minimum Enclosing Symmetrical Model. Then inflates this model by allowances from presets. Then it offsets 0-3 adjacent faces on the pavilion and on the crown, which are in almost perpendicular directions. From these faces, you can determine the orientation of the model after blocking in the space of the SmartRecut solution.
New algorithm is available in the allocation algorithms as a new line "22. MESM for blocking":
The usage of the new algorithm is very similar to “20. MEC for round bruting “:
- Choose "22. MESM for blocking" algorithms
- Select the SmartRecut solution for which you want to obtain enclosed symmetrical model
- Press “Start allocation”. You will receive a new solution with “Blocking_MESM” cutting title and “MESM” allocation mark:
The MESM algorithm is adjusted via presets
There are two allowances for Girdle facets and for Crown & Pavilion facets. It measured in microns. If necessary, they can be set to zero.
"MESM Special facets for recognition": in any case, on the crown and on the pavilion, one set of close facets selects in perpendicular directions. This parameter specifies the number of facets in sets
Methods of model building
Method “Sample21”: new Model Building method by Sample
“Sample21”: new Model Building method with Sample.
To use this new building method you need to add a sample as usual with "Add sample button":
then two sample icons will appear:
One is for classic Sample building method and another with "(21)" marker is for Sample21 building method.
Choose "(21)" -marked sample to use Sample21:
MyRound Boundaries
In addition to the GIA Cut Grade, users can set their own MyRound intervals for each of these parameters via Appraiser editor. And these boundaries can create problems for the SmartRecut algorithm.
When setting boundaries, it is important to take into account not only Rounded values for GIA grade you want, but also "cells" Boundaries. We recommend setting the Appraiser boundaries for these parameters so that the distance from the left MyRound boundary (Al) to the nearest larger Boundary of the "cell" is more than (0,25 * Size). Similarly, the distance from the right MyRound boundary (Ar) to the nearest smaller Boundary of the "cell" was more than (0,25 * Size). See "Good Appraiser boundaries". Let's call (0,25 * Size) it a "recommended cell size".
For most of the parameters, the "dead zone" is less than "recommended cell size". But after subtraction of the "dead zone" size from "recommended cell size", the optimization has a very small search area, therefore it is statistically more profitable to work in a farther green "cell", and ignore the red "cells". See "Bad Appraiser boundaries".
Even more bad situation for optimization when there are no green cells. See "Problem Appraise boundaries". And there are enough one-parameter bad boundaries to make all 6D-cells are red. For example, LowerGirdleLength [77, 78.4] or narrower boundaries create this situation. At the time of Carbon 1.4.4, the second stage of SmartRecut does not correct the quality of the GIA Cut Grade in such situations. In the future, one of the red "cells" will be selected in such a situation, but this does not cancel the recommendation about "recommended cell size" = (0,25 * Size).
Example
Let's take a look at StarLength as an example. For StarLength "recommended cell size" = 1.25%. There are 3 MyRound intervals in the figure
Interval I1 = [47, 48.5] is problem. It contains two red cells I1a = [47, 47.5] of length 0.5% and I1b = [47.5, 48.5] of length 1%. Both are shorter than "recommended cell size" = 1.25%
Interval I2 = [51.5, 58.2] is bad. It contains two red cells I2a = [51.5, 52.5] of length 1% and I2c = [57.5, 58.2] of length 0.7%. And one full green cell I2b = [52.5, 57.5].
Interval I3 = [61, 65.5] is good. It contains two green cells I3a = [61, 62.5] of length 1.5% and I3a = [62.5, 65.5] of length 3%. Both are longer than "recommended cell size" = 1.25%. If you reduce I3 to [61.3, 65.5] it becomes bad. If you reduce it to [61.3, 63.7] it becomes problem
Dead Zone and Safe Boundaries
The current sizes of the dead zone are shown in the table. If you set narrow limits on the parameter in MyGIA, you must take into account the dead zone size and not fall completely into it.
It is important to understand that the "Safe Boundaries" option will increase the size of the dead zone by margin. Below are the sizes of the dead zone in Safe Boundaries mode.
For example, in "Safe Boundaries" mode, you cannot require LowerGirdleLength exactly 71 or 72,73,74,76,77,78,79. Of the round values, only multiples of 5 are allowed.
Particular attention should be paid to the Pavilion Angle parameter. Its dead zone in "Safe Boundaries" mode occupies almost the entire space. Moreover, there is still a small chance that a GIA Cut grade error will be detected with margin = 0.06. For this parameter, Smart Recut can only technically guarantee safety when Margin < 0.049 (because of red equality in the table)
SmartRecut Girdle control upgrade for in-house cuts
During SmartRecut AnyCut optimization, the Girdle_Shape1stDerToleranceModule and Girdle_PointsAxialSymmetryIdeality parameters can create contradictions. The first one tries to keep the girdle shape of the Recut solution. The second one tries to make the girdle perfectly symmetrical. If the Recut solution girdle is not perfectly symmetrical, then an unresolvable contradiction may result. This is mainly a consequence of user errors during cut registration. Examples of such errors are in Girdle_PointsAxialSymmetryIdeality
In this version, SmartRecut uses Facet Types to determine the symmetrical sectors of the girdle and averages the start girdle shape of the Recut solution over reliable symmetrical sectors. Due to this, the probability of an unresolvable contradiction is significantly reduced. And the correlation between the Girdle_PointsAxialSymmetryIdeality parameter and the AreaLoss value improves.
SmartNormalize automatically fixes simple errors in FacetTypes
To increase model symmetry and remove excess facets, you can use the Smart Normalize algorithm. Previously, if the model that you were going to normalize had mistakes in its facet types, Smart Normalize could provide non-symmetrical solutions. Now the algorithm is improved: it tries to fix mistakes in facet types and then provides excellent symmetry.
Hint This is especially useful when mistakes are not obvious to an operator.
Technical details:
- The algorithm tries to fix facet type mistakes using information about groups of symmetrical facets and which type dominates in a group. If the situation is clear enough, mistakes in facet types are fixed automatically and the algorithm finds the solution with the correct number of symmetry axes. If the case is too complex, the algorithm uses initial facet types without changes.
- Fixing does not change the initial model facet types but does change the resulting model - it will have different (fixed) facet types.

Control absolute value azimuths for in-house cuts
In previous versions, for in-house cuts the algorithm 19. SmartRecut (Brilliant, Oval, AnyCut) controlled only the azimuths symmetry of the facets. But a change in the absolute value of azimuths could lead to a big loss of the solutions performance.
Therefore two parameters have been added to control the tolerance of azimuths from the initial values. More "narrow" MainAzimuthsToleranceModule is tuned for only Main facets. Less "narrow" OtherAzimuthsToleranceModule is tuned for other facets.
Precise fixation of parameters StarLength and LowerGirdleLength in SmartRecut (Brilliant)
StarLength and LowerGirdleLength are parameters that greatly affect the pattern of the stone, but practically do not affect the mass. Sometimes there is a need to get a specific average value for these parameters. Now you can do this by setting an interval of 0.02 length in MyRound. SmartRecut solutions will have the value exactly in the center of the interval. However, when setting narrow boundaries, it is necessary to take into account the dead zone, especially when working in Safe Boundaries mode.

In-house cut workflow improvements
Compatibility of in-house cuts and linked appraisers between HP Carbon and Helium Rough/Pacor Client
Currently some allocation algorithms exists only in Helium Rough/Pacor Client but not in HP Carbon. Mainly there are semi-automatic or manual algorithms, that are available in Tools mode (like "Fixed Diamond Weight", "Change cut" and so on).
Therefore the same project is need to be open in both programs (HP Carbon and HR/PC) and compatibility of cuts and appraisers is required for work convenience.
Previously registered in HP Carbon Cuts and linked Appraisers are automatically loaded to Helium Rough since version 7.4 if Helium Rough is installed on the same computer.
Hybrid Appraisers (with Absolute and Relative parts) has limited compatibility:
- Helium Rough program version 7.4 doesn't have option to enable/disable Absolute and Relative parts.
- There is no convenient switch between profiles
Helium Rough will allocate with the same conditions of hybrid appraiser like they was during exit from HP Carbon. Under conditions we mean absolute, relative parts and profile .
Example of work:
Suppose we have following list of in-house cuts in HP Carbon:
When we run Helium Rough then the same cuts will be available in panel Diamond.
To run allocation with in-house cuts it is required:
- To create new list in Rough Classification panel and add necessary in-house cuts there.
- Select Intervals/Appraiser Auto.
Auto Appraiser allows to run allocation with several cuts and their linked different appraisers.
Usability upgrade of in-house cuts presets
To simplify navigation, the parameters in in-house cuts presets are sorted into groups with the addition of prefixes in the names: "Girdle_", "Angles_", "Distances_", "ExtraFacets_"
Integrated documentation is connected for all parameters of the "Girdle_" group.
If you need to reduce the Area Loss of the SmartRecut solution, then decrease the Girdle_PointsAxialSymmetryIdeality via presets and restart the optimization.
Some exceptions are described in the integrated documentation Girdle_PointsAxialSymmetryIdeality or under in program.
Аutomatic adjustment of appraiser intervals for in-house cut to set start allocation form to EX group
During in-house cut registration program creates appraiser with parameter intervals from the selected template. Start allocation form which is used for cur registration could be out of EX group by some parameters.
There is new feature in software to adjust automatically intervals "Absolute Proportions" to set start allocation form in EX group that is required for correct work of further allocation.
The intervals adjustment is following: intervals from templates are shifted on the some value of parameters ("parallel shift" for parameter intervals of EX, VG, GD, ... groups). The value of the shift is found by software by such way that value of each parameter is exactly in the middle of EX group. Therefore all values of start allocation form are set in the middle of EX group. Intervals size [min, max] for each group are remained the same as in template.
