start angle and end angle calculations

[raghu.patthar]

Dear All,


I have the start point (x,y) and endpoint (x,y) and center (x,y). I want to calculate start angle and end angle for defining 2-d section arc. I did some calculations but i feel Pro-e calculates arc angles differently comapred to my calculation. If anyone, knows how to calcualte correct start angle and end angle, please let me know.


BR,


Raghu

You might need to convert your point/center co-ordinates to screen co-ordinates , as proe accepts/likes to have all co-ordinates in screen co-ordinates.

I am not sure if this is the only reason for wrong result at your end.Other experts please comment on this.

Thanks
