Here you can find information about what is new in HPOxygen Server version 5.3.42.

Inclusions - Grey Status

Now you are able to set Grey Status for inclusions of your model. Inclusions having this status will not be taken into account during allocation.

Solutions Report

The system now allows comparing solutions using Solutions Report. This report allows comparing solutions by main parameters including ASET and Office pictures.

To use the feature:

Customizing Profiles - Improvements

In HP Oxygen, each profile  consists of cutting parameter intervals and Smart Recut presets values. The system allows copying both cutting parameter intervals  and presets values into your own editable profile - there you can further tune them.

Now copying intervals and preset values is improved. You can:

Below is a brief description of how to work with the new features:

Managing Allocation Forms

Now you can manage allocation forms of your registered cuttings in the solution list.

How you can manage the allocation forms:

SweetLine Improvement

As the result of additional research, for the SweetLine parameter, the slope of the optimal line is changed from "negative 1:4,5" to "negative 1:6" which means "each 6° increase of CrownAnge is 1° decrease of PavilionAngle". This improves the accuracy of defining the set of solutions with the better optical performance.

Detailed information about using the SweetLine parameter is presented in the video below:

New Smart Recut Parameters

The new parameters have been added to the appraisers used by the Smart Recut algorithms:


This parameter is applicable to the following cuts: AnyCut (only when performing SmarRecut via Relative appraiser).

Defines how much (in %) the angle between normals of any neighboring facets can deviate after Smart Recut comparing to Recut.

If at least one of the neighboring facets is girdle or culet, the limitation is not applied. The girdle shape is controlled by the Girdle Shape Tolerance parameters. The culet is not taken into account.

Calculation

The parameter is set manually via preset and control the rule:

A(1+min/100) < B < A(1+max/100)

Where:

  • A - the angle between normals of neighboring facets after Recut
  • B - the angle between normals of neighboring facets after Smart Recut
  • min - a left boundary in preset, should always be negative, for example, "-25"
  • max - a right boundary in preset

Usage and Examples

If the parameter set to "-25, 50" and the angle between normals of neighboring facets after Recut (A) is "10°" then:

  • 10(1-0.25) < B < 10(1+0.5)
  • 7.5 < B < 15
  • the angle between normals of the same facets after Smart Recut (B) should be within the interval from 7,5° to 15°.

This parameter is applicable to the following cuts: AnyCut (only when performing SmarRecut via Relative appraiser).

Sets limitation “not less than this value” for the angle between normals of any neighboring facets.

If at least one of the neighboring facets is girdle or culet, the limitation is not applied. The girdle shape is controlled by the Girdle Shape Tolerance parameters. The culet is not taken into account.

Calculation

The parameter is set manually via preset.

Usage and Examples

Should be used to avoid transforming the neighboring facets into a single plane.

The current default values are:

Client Versions Integration - Multi-Diamond Algorithms Enabled

As part of the integration of the different Oxygen client versions, the algorithms producing multi-diamond solutions are enabled in the system and now available in the Algorithm list.

Fixed Unknown Cut Grade Because of Girdle Value

The calculation error leading to a negative girdle and thus unknown cut grade has been fixed.


From: Utpal Mistry 

Dear Sergey

Attached project shows negative girdle due to new GIA rule. which gives unknown cut grade.

For the presented example and similar cases, the girdle height now will be "0".

Fixed Problems and Improvements

The following fixes for the known problems and improvements have been implemented:
