eagle - how to put smt components on bottom layer

Hello all. I'm trying to lay out an eagle pcb with both smt and conventional components and I'm trying to make it single -sided. Does anyone know how to put an SMT part on the bottom layer? Thanks

Use the "mirror" command (GUI button just below "move") to flip things to the other side. Or use the middle mouse button during a "move" operation.

That's not completely true!!! Some components cannot be mirrored, like transistors... If you want have PTH transistors on top and SMD on bottom, and you mirror the board, You'll get mirrored transistors pads. How do you manage this if you don't want bend pins? ;-)
yes, right.. you must change the SMD pad in library to combine SMD n PTH component.. if you just mirror the board, the PTH pad become wrong..

Thank you sooo much
if you are going to make the pcb yourself, just do everything on the top side, when you print the toner transfere paper or transparency sheets you would not need to do any flipping of the image
