 If this value is set to 0, the ironing toolpath will start directly at the perimeter edges without any inward offset. This means the [ironing pattern](#pattern) will extend all the way to the outer boundaries of the top surface being ironed.

+## Angle Offset
 
-The angle ironing is done at.  
-A negative number disables this function and uses the [sparse infill direction](strength_settings_infill#direction).
+The angle of ironing lines offset relative to the top surface solid infill direction. Commonly used ironing angle offsets are 0°, 45°, and 90° each producing a [different surface finish](https://github.com/SoftFever/OrcaSlicer/issues/10834#issuecomment-3322628589) which will depend on your printer nozzle.
