When creating a tube mesh, lets say with a diameter of 16 and a thickness of 2, i'd expect the outer ring diameter to be 16 and the inner ring diameter to be 16 - 2 -2 = 12.
To clarify what I'm trying to achieve is this: a cylinder, 8 sided, with a diameter of 12, encased by a tube, 8 sided, diameter 16 and thickness 2, without gaps or overlaps. But whatever value i put in as thickness, there is always either a gap or an overlap with the cylinder. How to interpret and set tube thickness correctly? Thanks
