Consider firstly parameters of generic parametric cut. There are first stage of allocation by global algorithms and second stage by SmartRecut algorithm. Global algorithms of allocation vary values of considered parameters for search of optimal solution. But SmartRecut algorithm doesn't use these parameters. Also note that these parameters doesn't participate in final solution grading. An editing the limits of these parameters is available in a user-friendly software interface in the panel appraiser editor. Previously, this operation was laborious, requiring manually edit of the appraiser txt-file.

Secondly consider parameters from the In-house appraisers. SmartRecut algorithm uses only these parameters during it's allocation stage. After getting of solutions the grading is produced by only these parameters. Sometimes solutions of global algorithms may have values of certain parameters that exceed the Excellent boundaries. In most cases SmartRecut will be able to fit these values in the Excellent group.

There is a sample of running of SmartRecut for one of Smart Cut - Radiant P28C24. There are solutions of SmarRecut with high yield and good optical performance:

Note
titleImportant! Known issues!

In the following cases, SmartRecut may not work on SmartCut solutions:

  • Heart. Cut is not completed.
  • PearPro, Pear_wBT.P24C32. Global algorithms may have mistake in values of CuletOffsetLength more than Relative interval. So Absolute and Relative intervals for SmartRecut are not compatible.
  • Princesses (2S, 3S, 4S, 5S). Global algorithms have too big slope angle asymmetry for square Facet Types. It is conflict with SmartRecut parameter Angles_FacetTypesSlopeIdeality. The values ​​of this parameter can be temporarily increased in presets for Princesses.
