I agree that autocad is the tool to use if you work with dxf files, but I would work with the gerbers in a gerber tool if I were you. It gives 2 things. One is that you get to see the allegro output and see if you got what you wanted to get and second you can mirror the any layer you want to in the gerber tool and then print the whole mess. Mentor provided gerbtool with the expedition tool and it worked great. I have since bought it and wonder why cadence does not provide the same capability as the basic gerbtool is cheap ($600 if I remember correctly). If you want to check on it it is sold by a company named Wise. Good luck, Kevin McCowan Sr. PCB Designer TSI Telsys
I don't know the answer to your question, but mirroring is so easy and-----------------------------------------------------------
effective in autocad, that's where I do it. Another thing I do in autocad
is hatch the pins for the assembly drawing, as they come over unfilled. To
do this easily I export the pins on their own autocad layer, so that I can
grab them all to hatch solid.

Subject: [PCB_FORUM] Mirror dxf file?
Hello all,
Is there a way to mirror a dxf file output?
We used to create a plot file, mirror on import to .brd, then dxf out. This creates a DXF on pen layers.
We want to mirror all of the bottom side components, board outline,
etc...for the bottom side assembly drawing. But also would like to output
the DXF with real layers instead of pen layers.
Thanks, Mark
