    Ok so how do i mirror?

    I downloaded the Seeed_Gerber_Generater_2-layer.cam and use that off the site:

    http://support.seeedstudio.com/knowledgebase/articles/493833-what-is-gerber-file


    Do i click mirror for every one of the layer below?
    • Top Layer: pcb.GTL
    • Top Solder Mask: pcb.GTS
    • Top Silkscreen: pcb.GTO
    • Bottom Layer: pcb.GBL
    • Bottom Solder Mask: pcb.GBS
    • Bottom silkscreen: pcb.GBO
    • Board Outline: pcb.GML/GKO
    • Drills: pcb.TXT

    I have never heard of this or had to do It?
    I have used Orcad and Kicad from local PCB manuf to US and then offshore (China) and submitted just Gerber files.
    No mirror required?

    You do not to mirror all the layer files in Gerber format. You just need to provide all the Gerber files and drill file to the PCB manufacturer. They know how to recognize them.

    The standard (with our local PCB manufacturer's instruction PDF file) which accompanies the order form, states that ALL layers must appear in GERBER format, viewed TOP view, so the bottom layer will be seen as if viewed from the bottom. The CNC ( or other) software at their end will arrange it correctly.

    Legacy thread:
    But the ones I got back from Seeed were fine with the Gerber produced by Kicad.

    You should know, all manufacturing Gerber layers are viewed from the top side, so if it's bottom layer, it should be mirrored and could connect with the top layers correctly
