CATIA二次开发源码分享： 获取所有的圆角类型并着色
CATIA二次开发源码分享： 获取所有的圆角类型并着色
本部分主要学习如何对特征进行颜色标记处理！
重要的是思路，通过CATIPrtPart 获取CATIDecendants接口，在这里可以设置要查询的类型，通过获取的特征得到特征对应几何的Brep信息，从而可以调用可视化的方法进行颜色处理！对于CATVPMesh的类型主要可以处理颜色和透明度。

颜色属性类别如下：本文用到了颜色和透明度
enum CATVisPropertyType {CATVPColor,
CATVPOpacity,
CATVPSymbol,
CATVPLineType,
CATVPWidth,
CATVPInheritance,
CATVPLayer,
CATVPShow,
CATVPPick,
CATVPLowInt,
CATVPRenderingStyle,
CATVPAllPropertyType
}
几何类型对应的颜色类型如下： 本文使用的是CATVPMesh
CATVPGlobalType
This type defines the group of property types:
CATVPPick
CATVPShow
CATVPLayer
CATVPMesh
The geometry is surfacic.
This geometry uses these property types:
CATVPColor
CATVPOpacity
CATVPEdge
The geometry is an edge.
This geometry uses these property types:
CATVPColor
CATVPWidth
CATVPLineType
CATVPLine
The geometry is a line.
This geometry uses these property types:
CATVPColor
CATVPWidth
CATVPLineType
CATVPPoint
The geometry is a point.
This geometry uses these property types:
CATVPColor
CATVPSymbol
CATVPAsm
The geometry is a set of geometry. This type allows you to have inheritance.
This geometry uses these property types:
CATVPColor
CATVPInheritance
CATVPWidth
CATVPLineType
CATVPOpacity
