Pro Engineer software rapid modeling method of round brilliant cut jewels

Abstract

The invention discloses a Pro Engineer software rapid modeling method of round brilliant cut jewels. The method includes the following steps that: (a) calculation formulas of the dip angle of an uppergirdle facet, the dip angle of a star facet, the dip angle of a lower girdle facet, maximum girdle thickness and the like are inputted into a relational table generated by the modeling of any one round brilliant cut jewel, two types of parameters are generated in a parameter table, wherein the two types of parameters include user-defined parameters that require a user to defined parameter values,and locked parameters of which the parameter values that have been locked by the calculation formulas; (b) the user sets up a modeling program and sets the specific values of the user-defined parameters in the parameter table; and (c) the modeling program is operated, the specific values of the user-defined parameters are imported into the calculation formulas for calculation, so that the geometric information model of the round brilliant cut jewel is obtained and displayed. According to the modeling method of the invention, after some cutting parameter values are inputted into the Pro Engineer software, a jewel model can be quickly constructed, and therefore, drawing efficiency can be improved, and a large amount of geometric information can be obtained.

Description

technical field [0001] The present invention relates to a method for software modeling, more specifically, relates to a method for rapid modeling of round brilliant gemstones with Pro Engineer software. Background technique [0002] Round brilliant-cut gemstones (including diamonds), also known as standard brilliant-cut gemstones, are the most used styles of gemstones on the market today. A standard round brilliant-cut gem is composed of a crown and a pavilion. In the gem processing process, the gem is usually modeled with computer software, and then processed according to the built gem model, and then the finished gem ( Loose diamonds) are tested for cut parameter grades. [0003] Usually, Pro Engineer software is used for routine modeling of round bright and bright cut gemstones. The following parameters will be used in the modeling process: girdle diameter (D, in mm), upper girdle inclination (β′, in ° ), crown angle (β, unit is °), table width (a, unit is mm) or table ...
