Allegro Artwork Generation Error

Mohsin Hayat

I am generating the Gerber files for PCB. All the layers are generated successfully except the PWR/GND Planes. I don't know what would be happened with the generation of the Planes.

Please find the attached ERROR during the generation. Its saying that the Layer Polarity of the ETCH/L6GND doesn't match file polarity of Positive.

Please help me out in that problem.

    It sounds like you have Negative Artwork checked in Setup>Cross Section, or set the Gerber output to Negative for the Films outputting those layers. If you change the type in the cross section, you will need to regenerate the Shapes and check that the clearances in the Constraint Manager match those that you had from the Anti-Pad / Thermal settings in the Padstacks.
