Doing Layout on two outer layers in OrCAD

Although I am not currently using OrCad layout, one would assume there is a 'mirror' command somewhere. If you mirror a component, it (by definition) should get placed on the opposite side of the board.

Yes, I found the solution - select a part and then change the layer to bottom (or press 't' to toggle)

A straight mirror can be dangerous. Protel 99SE has a mirror and change layer commands.

The Mirror is handy if you want to mount a chip upside down. Why you ask? I once did a demo board for a remote control. All the SMD component were mounted upside down with holes cut into the PCB so that the height restrictions were met. I believe the final version was going to be chip-on-board with thick film discrete.

Did you manage to make split through- plated holes for the resistors, caps etc? Can this be made by PCB manufacturers?

I must use OrCAD, so not much choice there. I was given a board and asked to repeat what's on the board as close as possible. Why is straight mirror dangerous and what's a better solution?

It's much more likely someone will be able to prove your counterfeit board really does infringe directly on someone else's design? :-) Whereas if you at least shove a few components and traces around you might argue both the boards were manufacturer's references designs maybe? :-)

Well, it's part of research project and the previous board was done in the different software for the same supervisor, so I should be safe:)
