17. SmartZoom is fast (from few seconds for simple till couple of minutes for complex models) algorithm which can be run for one of the current solutions and results in slight increasing of weight in comparison with start solution due to slight imperfections of cut shape, which do not decrease the overall grade. These imperfections are extra girdle facets, girdle height change and girdle shape (roundness) change.
So 17. SmartZoom allows to improve existing solution by weight (up to few percents) due to adding of some imperfections in shape.
Algorithm 17. SmartZoom works for any cutting including ASCII.
There are following main differences between 17. SmartZoom and Pacor "Increase&Intersect" option:
To define thresholds described in above list, please contact your distributor.
An area of 17. SmartZoom application:
1) Algorithm 17. SmartZoom is not effective where cutting has NO vertical girdle (for example, scanned ASCII cuts) and could return no extra weight.
2) Algorithm 17. SmartZoom is not effective for already existing SmartRecut solutions and could return the same weight of SmartZoom solutions if algorithm is run for SR solutions.
To use algorithm it is firstly required to get solution by any method - ether "recut" algorithm or import from Pacor or other possible for import program, select it in Plans&Scans tab of Allocation solution panel, then select 17. SmartZoom algorithm in the list of algorithms and press Run.
Algorithm gives several solutions (up to 8) of 4 colors: each color corresponds to a preset. There are 4 presets that differs in intensity of shape imperfection from each other: quantity of extra facets, their position (crown girdle extra facets or pavilion girdle extra facets), height of extra facets, intensity of girdle shape distortion. There are 4 presets Small (Cyan), Medium (Green), Large (Yellow), Extra Large (Orange) - name corresponds to intensity of imperfection.
Solutions of 17. SmartZoom has corresponding to presets colors.
It is possible to get either one solution for one preset and solution cutting will have name "SmartZoom" or 2 solutions for one preset and solutions cuttings will have name "Smart_Nat" and "Smart_EF".
These 2 solutions in last case differs by Extra Facets set on model: "Smart_EF" always has flat Extra Facets whereas "Smart_Nat" leaves shape of initial rough unchanged in the place of extra facet - it could be few natural facets of rough or cavity if rough stone has cavity in this place:

New Oval cuttings are available in Cutting list:
There are totally following Oval shapes are available:
Oval_WBT_C32_G64_P24_2017_JUN_21 | Oval_C32_G64_P24_2017_JUN_21 | Oval_C32_G64_P20_2017_JUN_21 |
---|---|---|
Oval_C32_G64_P22_2017_JUN_21 | Oval_WBT_Shifted_C32_G64_P24_2017_JUN_21 | Oval_WBT_C32_G64_P24 |
---|---|---|
Note that first cutting Oval_WBT_C32_G64_P24_JUN_21 and last cutting Oval_WBT_C32_G64_P24 has the SAME topology but first is the newest and has more parameters and can result in better solutions. So we recommend to use first cutting Oval_WBT_C32_G64_P24_JUN_21.
Athena cut position in report now caclulates through rotation axis. All crown and pavilion facets are recognized as main facets:
