FeatureWorks it's auto fuction in SolidWorks. And sometimes SW can't recognize all features. But you also try manualy recognize this. Check my screenshot.

Thank you very much Sir

but i know all this and i tried to recognize it automatically and manually but the program failed to recognize it because the teeth are not perpendicular they are in angle with side faces so i ask if there is a trick i didn't know to make the program able to recognize it

thank you again

Best regards
