July 14, 2006 - Helium Polish 1:1 version 3.80 (build 74) and Helium Polish 1:2 version 3.80 (build 75) are released.

The features of new release:

1. The Girdle Type parameters were substituted by new parameters: Crown Painting and Pavilion Painting. They estimate crown and pavilion independently. New parameters are added to the reports for round brilliants.
2. Improved building of fancy cutting and its semipolished.
3. The mode of construction various cutting by ASCII is included.

New parameters Crown painting and Pavilion painting description

Following new parameters are added to the reports for brilliants:

Crown painting, degrees
Crown painting, notches
Crown painting, text
Crown painting type, text

Pavilion painting, degrees
Pavilion painting, notches
Pavilion painting, text
Pavilion painting type, text

Painting parameter defines deviation of halves' facet azimuths from ideal. For each lower and upper facet software calculates difference between azimuth of this facet and azimuth of the nearest main facet. The ideal brilliant will always have this difference equal to 11.25 degrees. Real stone may have some deviations. So, deviation of this difference from ideal 11.25 degrees is the (signed) value of the "painting, degrees" parameter.

"painting, notches" is defined as following:

painting, notches = abs(painting,degrees)/3.75 <degrees>

It is the same deviation but unsigned and dimensionless.

Such deviations from ideal lead to changes in the girdle shape. They may make girdle thinner or thicker.

There are text descriptions for these deviations besides numerical values. The "painting, text" parameter may be one of the following depending on the "painting,notches" (average) value:

(0.0 - 0.1) Absent
(0.1 - 0.3) Very small
(0.3 - 0.8) Small
(0.8 - 1.2) Practical
(1.2 - 1.8) Big
(1.8 - 2.2) Very big
(2.2 - oo) Huge

There is one more text description of the whole girdle for crown and pavilion sides: "Crown painting type" and "Pavilion painting type". It may be one of the following: "Painting" or "Digging" or empty. If painting parameter is rated as "Absent", the "type" is empty. Otherwise the "painting,degrees" (average) parameter is considered. If it is less than 0, the type is "Painting", otherwise it is "Digging".

Construction any cutting by ASCII files

New mode allows constructing model of scanned diamond with any cut. ASCII files uses as a sample.

There is the example of scanned model:

Result. Scanning model

Open 3D model* of the scanned diamond

Sample model from ASCII file

Open 3D model of the sample diamond

*To open 3D models you need a free GemAdviser software
