Zoom modes

New zoom behavior is introduced.

Cut Analysis: Carat weight and Spread among performance indexes

Carat weight and Spread (Ct. and/or percent) now can be stored in Cut Analysis report along with other performance indexes of the cut.

The indexes are checked on in the list by default.

Cut Analysis: Parameter validation option

A third option of parameter behavior is added to Cut Analysis interface.


Check inside interval is useful when the parameter in question is dependent on the other parameters which are set to vary, and thus may fall outside of acceptable range.

Cut quality estimation

Upon changing of model proportions or opening a new file, the calculated cut quality figures are marked as obsolete, so as not to misinterpret the old data as belonging to the new model.


  • Girdle reflections drawing mode is now available to the users with Pro license.

  • Color estimation method was updated, so the results on the same model may have changed slightly since the previous version.

  • Bug that caused an error message to appear upon opening of *.gem or *.srn files is fixed.
  • Panel size issue in Chinese versions Windows 8.1 is fixed.
  • Issues with variation of certain parameter pairs (Crown angle + Table diameter, Crown Height + Table diameter) in Cut Analysis (Pro version) are fixed.
  • Spontaneous switching to Photoreal mode upon initiating Pro Cut Analysis is fixed.
  • Failure to import certain *.stl files saved by third-party software is fixed.
  • A warning message while loading a *.dmc file without parametric cut information is suppressed.
