I am using a cylinder to perform Boolean cuts on a cube

After the cutting is completed, I want to choose the rings on the original cylinder,like the picture show

Can selection be made through certain APIs or shortcut keys instead of manual selection

enter image description here

    $\begingroup$ The selection state is copied from the target object when the boolean modifier is applied. $\endgroup$

    $\begingroup$ Yeah +1 to @unwave if you have those edges selected on the cylinder before applying the modifier they will be selected on the applied object. $\endgroup$

  • $\begingroup$ @unwaveu yeah it works, But I still need to manually select. Is there a way to automatically select it $\endgroup$ Commented Jun 20 at 6:50
  • $\begingroup$ How is Blender supposed to know what you want to select? Automatically select all horizontal loops? $\endgroup$
