Boolean tools (Add, Subtract, Intersect, Slice) can be used on smeshes, so long as they are combined only with other smeshes or TC Surfaces. The result of any Boolean involving a smesh is a TC Surface. All of the facets of the smeshes and all of their Smoothing level subdivisions are converted to Facets on the resulting TC Surface. This can radically increase the number of apparent facets on the object.
