This plugin provides copy/paste commands for polygons. You can copy polys from one object and paste them into others. It preserves Selection Tags, UVW Coordinates, HN Weighting, and VertexMaps, in the sense that data from these tags is pasted into matching tags Tags of the same type with the same name.
