Hello,

Did you try using IMAQ Find Circular Edge function with a partial ring setup for your search? I'm attaching a simple example that searches a circular edge on an annulus area specified by the Circle or Annulus parameter. Just point the example to the attached sample image.
I hope this helps. Let me know if you have further questions regarding this.

Hi Yusuf,

Thank you so much for your suggestion and sample code.
It's very helpful and solve my two weeks problem. Actually, I have tried to use this function already, but I never tried to use the start angle and end angle, so I thought that this function must use only for completed circular. How foolish am I!!!

With appreciated and impressive
I can continue my project from now.
