We show that 3d N=2 partition functions have the structure of q-deformed CFT correlators involving degenerate primaries. We use crossing symmetry,the CFT counterpart of flop invariance, to determine 3-point functions. By means of these 3-point functions we construct non-degenerate correlators which we identify with partition functions of 5d gauge theories. 3d gauge theories are then interpreted as co-dimension two defect theories.
