Allocation of 3 or more diamonds has become the standard for all sizes and types of rough stones. On average, a solution contains 5 diamonds. An important question when allocating multiple diamonds is "How to perform Sawing?" Not all solutions with 4 or more diamonds can be sawn using modern sawing technologies. The picture shows an example that cannot be sawn.
Introducing our new algorithm "24. MultiDiamond."
...
Users can specify the number of diamonds they want in a solution and the algorithm will find that many diamonds in the scan model.
When searching for the three largest diamonds, the algorithm prioritizes maximizing price. From 4 diamonds onwards, the algorithm also considers the need for existing sawing.
Furthermore, users can adjust the thickness of sawing planes used in the optimization process, and choose the "Variation" mode. Currently, two options are available:
"FixedForm" to produce solutions exactly of the same form as the allocation forms registered within the cut. Only scale or position may be changed
"FlexibleForm" to produce solutions in the limits specified by the appraiser.
...
The algorithm "24. Multinext" has also been added. It operates on one or multiple selected solutions. The user chooses how many extra diamonds need to be added to the selected solutions. In the case of multiple selected solutions, the algorithm will work independently and in parallel on each of them. "24. MultiNext" uses a allocation method identical to "24. MultiDiamond" starting from third solutions. The result of "24. MultiNext" can always be sawn with pie sawing.
The algorithm "24. MultiNext" with FixedForm Variation, compared to "24. MultiNext (FixedForm, BasicSawing)":
1) Is faster
2) In most cases provides higher solution price
3) Frequently cannot be sawn without using Pie Sawing.
...
When the first layer is moved, Bound Swim runs for all polished diamonds in the solution.
Typically, each layer isolates one polished diamond from the remaining ones.
For subsequent planes (second, third, etc.), the working zone remains unchanged for previously isolated polished diamonds, and the algorithm is not triggered for them.
Compatibility with Different Section Types (Layer, Pie)
...
Context menu appears for the currently selected diamond, but now you to click on the diamond directly in the scene to make it active, without needing to select it from the diamonds panel first.
Layer selectable from the panel
Layers are now selectable like diamonds, enabling the use of object movement tools on the selected layer.
Operation "View along sawing direction"
A new context menu item, "View along sawing direction," has been introduced for layers. This command arranges the scene so that the layer becomes horizontal.
Scene objects - layers
...
An additional column has been added to the sawing thickness table to display the minimum mass value, indicating the interval for the corresponding thickness value.
Sawing parameters
The sawing layers have been upgraded with new data and an improved interface. The "Create sawing data" command in the solutions context menu has been replaced by two distinct commands: "Create sawing layers" and "Generate sawing data."
Here’s the key difference: "Create sawing layers" removes all existing layers and populates the solution with appropriate new layers (similar to the previous "Create sawing data" command). In contrast, "Generate sawing data" simply adds additional data to the already existing layers.
This additional data includes the following: generating half-planes where necessary, creating a glue point, establishing sawing directions for each layer, and developing a rough projection contour (blue line).
The parameters for sawing directions can be defined in "General Settings -> Allocation -> Sawing Parameters."
You can also set parameters for each layer individually by clicking on the "Sawing parameters panel" in the layer context menu.
The available parameters are:
For Plane:
...
- Shaping offset
- Sawing direction
Here is a brief description of each parameter:
...
To create a shaping, you can use the "Generate girdle shaping" command from the diamond context menu. For shaping sawings, there is additional data provided: a shaping contour around the girdle (yellow line).
Blocking layers
You now have the option to create blocking layers when generating a preplan. To do this, simply check the "Create layers for blocking facets" checkbox and click the "Create preplan" button.
The sawings will be positioned with an offset from the facets. You can modify the offset value in "General Settings -> Allocation -> Sawing Parameters -> Facet Distance".
Pinning Solutions in the Solution List. Rendering upgrades.
...
When loading a project, the Main Scan is automatically pinned if its processing stage is Rough, Saw, or Bruted. In Recut mode, scans with these stages appear transparently instead of in lines mode—this can be adjusted in the rendering settings, where separate display modes for Rough and Polished scans are now available.
Saw rendering has been improved: non-visible parts are now shaded, and the active layer is highlighted in red with thicker lines. For users who prefer solid mode, this option can now be applied to layers(planes) in the Rendering Settings.
Sample Facet Types
...
The realization of an unattractive girdle shape in a Fancy diamond often comes too late, after the stone has been cut and fails to attract buyers. Operators aiming to increase carat weight may enlarge the girdle shape without having the necessary knowledge and tools to assess its beauty.
To address this issue, we have developed the Shape Deviation parameters. These parameters help to compare how the girdle shape differs from the ideal shape, just like the 2RRoundness parameter does for the Brilliant cut. The Shape Deviation Grade enables operators to easily reject unacceptable girdle shapes.
After aligning the girdle shape of the current model with the ideal girdle shape linked to the current cut, we calculate the distances between the two curves. These distances are presented as the Shape Deviation Plot and Shape Deviation Ideal Girdle. Next, we identify azimuth intervals of 11.25, 22.5, 45, and 360 degrees where maximum difference in distances between shapes are observed, and estimate these values. It is in these locations where the imperfections in the girdle shape are most noticeable. The Shape Deviation Plot highlights these areas with rectangular windows, along with indications of global maximum and minimum values.
Deviations where the current girdle shape is wider or narrower than the ideal shape are color-coded. This information is also depicted in the Shape Deviation Ideal Girdle image. Here, the current model is outlined in black, with areas highlighted in blue and red denoting the extent to which the girdle shape of the current cut deviates in width from the ideal girdle.
Global maximum and minimum values are also represented in both pictures.
The parameter is currently available for the following Octonus cuts:
...
In I3D Comparative Remaining Depth mode, min/max indiaction added to the graph plot and 3D scene.
Azimuth markers were added to the 3D scene to make a more convenient navigation between the graph plot and the scene.
Facets Edge With for Princess cut
...
Two additional ways to create a preplan have been introduced: from the layer's context menu, you can select "Make preplan for cutting part" and "Make preplan for part on glue." "Make preplan for cutting part" creates a preplan for the part of the rough that should be cut off by the sawing. Typically, this is a sawing preplan for the diamond being cut. "Make preplan for part on glue," on the other hand, creates a preplan for the remaining rough part. This is the part of the rough, that remains at the glue point after being cut by this layer.
Fixed problems and improvements
- Swim, Ballon and Change Cut algorithms now use correct sawing thickness according to layer general settings.
For instance, diamonds perfectly alligned to the layer with a thickness of 0.15 mm, corresponding to a rough weighing 8.84ct(between 5-10 ct interval).
- Contact zone indication now updates, when the main scan changed.
- Layer weight/width display is fixed for some extraordinary layers with more than 2 cutting edges.
- Now the "Open Sample" dialog remembers the selected method, and the next time the dialog is opened, it will be automatically selected.
