That brilliant , thank you Leon . Appreciate the help .

Ewood42 , what you mean by xform the avoidance geometry ?

Hi Lads , Just quick question for you's can you tell me using a Area Milling in 2D Toolpath can you somehow increase the tolerance on avoidance region as even that I am avoiding the surface it avoids but it comes very very close to it . Can you change that to give at least 2 or 3 mm of clearance ? Thank you
