I have need of a infill that can be concentric. For now I make the skin very thick and turn off top and bottom. But I would like to make all upper and lower skins concentric while using a Rectilinear or Fast Honeycomb as infill, for structural durability. I also on occasion require a sparse infill, of concentric to allow flexibility.

On the INFILL tab, have you tried setting EXTERNAL INFILL to Concentric?

Yes, thank you. Good suggestion. I though this was for other functions, such as support structure not skin.

However still need circular, or perimeter pattern based internal infill.
