ZW3D 二次开发-创建圆锥体

使用中望3d用户函数 cvxPartCone 创建圆锥体

函数定义：

 ZW_API_C evxErrors cvxPartCone(svxConeData *Cone, int *idShape);
 typedef struct svxConeData
 {
     evxBoolType Combine; /**<@brief  combination method */
     svxPoint Center;     /**<@brief  center of bottom face */
     double Radius1;      /**<@brief  the first radius (mm) in bottom face */
     double Length;       /**<@brief  length (mm) along Z */
     double Radius2;      /**<@brief  the second radius (mm), 0 default */

     int useAxis;  /**<@brief  flag to use axis (0 to use plane, 1 to use axis) */
     int idPlane;  /**<@brief  optional datum plane (0 t
