Hello - it looks to me like your polysurface is unnecessarily broken up into multiple faces - is the intention that the cylindrical shapes be true circles in cross section and be simple straight cylinders off center with each other? If so, I’d just go ahead and make them that way. Apart from being simpler you’d only have surfaces to offset on and not polysurfaces.
