Data Structure for ARC WITH 3 points

[raghu.patthar]

Dear All,


I want to know what data structure is used within Pro/Toolkit for defining Arc with 3 points, namely Start Point, Endpoint, Center and radius.


It is certaily not Pro2dArcdefsince it contains only:


typedef struct
{
Pro2dEntType type; /* PRO_2D_ARC */
Pro2dPnt center;
ProAngle start_angle;
ProAngle end_angle;
double radius;
} Pro2dArcdef;

Please let me know your openions on this matter.

There is no specific structure for ARC With 3 points. You have to calculate the start angle and end angle to define the correct value in the pPro2dArcdef structure (2D) or the ProArcdata structure (3D)
