Goodwin Cut. Process flow
Goodwin cut is an advanced type of in-house cut which compared to the previous generation of cuts (aka ASCII-cuts) has more precise control over the cut geometry when changing the parameters, and also allows controlling the slopes of main facets.
Control angles for in-house cuts
To achieve excellent optical performance for in-house fancy shape cuts, it is necessary to control the Crown slope and Pavilion slope parameters, SweetLine parameter of your models.
...
- Make sure your model has the appropriate facet types.
- Normalize your model.
In Plans & Scans, right-click the best normalization result* and then, from the context menu, select Register as new cut. The Register new cut dialog is displayed.
Tip * Usually, the
"1. High_Sym_CFM" Smart Normalize preset (magenta colored) provides a result most suitable for further registration as a cut.- In the Register new cut dialog, specify Cut name.
- Select the Goodwin option.
- Make sure, the Create appraiser for your new cut from the selected template (recommended) option is selected.
In the list, click the appropriate template.
Which template to choose?
Template Description Cut sample* 1C1P For cuts having 1 tier for a pavilion. Allows controlling one angle of a crown (1C) and one angle of the pavilion (1P). The template is suitable for most cuts. 
1C2P For cuts having 2 tiers for a pavilion. Allows controlling one angle of a crown (1C) and two angles of the pavilion (2P). 
2C3P For rectangular cuts with 2 tiers for a pavilion. Allows controlling:
* separately of two angles of a crown (2C)
* three angles of the pavilion (3P):
* two on the 1st tier of a pavilion
* one on the 2nd tier of a pavilion
* Note that if you have several "Main" groups on the same Tier but different SubType, the priorities are used to define which group will be controlled by the parameters.

Goodwin type cuts support AnyCutBasic appraiser as well, but with the lack of important advantage of having slope angles in the appraiser.
Warning Note that selecting a template is not enough - later you must edit profiles manually.
Click Ok.
The new cut of the Goodwin type is created. It is added to the Diamond Allocation section, Cutbook > in-house Cuts. Also, from the selected template, a new hybrid appraiser is created for this new cut.Note title Important This is not the end, but just the beginning of the process. The next two "big steps" are obligatory to make your new cut/appraiser work effectively. The details about why it is important to populate a cut with the allocation forms and set your own boundaries for the linked hybrid appraiser you can find in the In-house cut registration, Hybrid appraisers, and related articles.
- Add allocation forms to your cut.
Edit the boundaries of your appraiser profiles.
Tip It is recommended to coordinate set boundaries of your appraiser with the allocation forms:
1. Select Manual appraiser selection.
2. Set the Appraiser and Profile to the one you are editing.
3. In the Diamond Allocation section, Cutbook > In-house Cuts, right-click your cut and select Show allocation forms. In Plans & Scans, allocation forms are displayed. They are graded by your appraiser/cut.
4. Make sure, grades are EX. If not edit the boundaries and repeat the estimation or consider deleting some forms.
Goodwin improvement for 2-tier pavilion cuttings
Improvement of Goodwin cutting technology with the use of intermediate layers.
Goodwin cuts registered with the Goodwin_GoldStar1C1P appraiser template now have an intermediate layer on pavilion during Recut optimization. If previously only the overall height of the pavilion changed, which proportionally changed the height of each layer, now each layer for 2-tier pavilion changes independently.
...
For automatic definition of new tier parameters facets on pavilion should be marked as Pavilion 1 and Pavilion 2 with Main or Corner type.
Gold Stars - new attribute for Facet Types
For many cuts, it is not always clear which facets are involved in the calculation of generalized parameters "Crown angle" and "Pavilion angle". At the same time, these parameters often play an important role in assessing the value of gems when they are chosen by buyers in the market. For clear work with these parameters, a new attribute has appeared in Facet Types - a gold star. The cut may have two gold stars. One on the crown and one on the pavilion. Gold stars symbolize the primary facets of the crown and pavilion.
...
If a cut has gold stars in Facet Types, then the parameters "Crown angle avg" and "Pavilion angle avg" are calculated by the facets marked by gold star groups. To calculate "Crown angle dev" and "Pavilion angle dev" from the gold star groups, Tier and Type are taken, most often Type will be Main. For all groups of faces with these Tier and Type, but various Subtype and/or "No.", their angle dev is calculated. And it is taken maximum of these devs in "Crown angle dev" and "Pavilion angle dev". Parameters "Crown angle" and "Pavilion angle" for example are found in Standard Report for AnyCut and other reports; in Cutwise data; in appraisers created by the new template Goodwin_GoldStar1C1P under the names "Crown Slope" and "Pavilion Slope".
Registration of Cuts with gold stars
When registering a new Goodwin cut, you can select the new Goodwin_GoldStar1C1P template. The following cases are possible:
...
The Sweetline calculation for Goodwin_GoldStar1C1P appraisers uses values "Crown angle avg" and "Pavilion angle avg" calculated from gold stars groups.
Registration of Cuts without gold stars
When registering a cut according to the old templates, you can also set the stars manually or registered solution may already have them. You can save them. But in this case, you need to understand that the parameters from the appraiser in the optimization will be calculated according to the principles laid down in the program, and not according to the gold stars. But the "Crown angle" and "Pavilion angle" in reports and Cutwise will still be considered by the gold stars. This may create some disaccords. Such a cut has certain advantages in the hands of an experienced user, but some danger in the hands of an inexperienced one.
If you want to avoid this, then at the time of registration of the first form, you can remove the gold stars if there are any. Gold stars are removed in the menu Facet Types via the gold star marked group context menu.
Reports for cut with gold star
Starting optimization on a new cut. Make sure that the values in the appraiser and in the Standard report match. We consider the pavilion as its gold star was set on a non-standard group.
...
And the same value is uploaded to Cutwise.
In-house cut workflow improvements
Own presets with its own appraiser for in-house cuts
Every 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.
...
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_"
...
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.
...

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.

Upload of correct data to Cutwise projects
When uploading from HP Carbon, ViBox, and DiBox to Cutwise, it is important to have data related to the same rough (its scan, solutions, final polished stones) within the same Cutwise project. See current recommendations and examples of how to achieve that in the article:
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.
...
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.
...
.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.
| Color label in SN | What does it mean in separate SmartNormalize | Color label in SN Batch | What does it mean in Smart Normalize batch |
|---|---|---|---|
| Good solution for registration. No errors found automatically. |
| Automatic registration |
| Good solution for registration. Automatically found warnings should not bad affect the work with this preform in the future. Possible Warnings: 1) "SmartNormalize found solution with AreaLoss in [0.05, 0.15]." |
| 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:
...
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.
...
| 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:

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.

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
