Positive/Negative plot mode

mfris

Hello,

I have finished (I think) my first board and I'm ready to send files to a board house for a quote.  Could someone explain how I should select whether to use positive or negative plot mode?  It's not clear to me when it might be appropriate to use one vs. the other, but I could imagine that selecting the wrong one could make my board turn out very, very wrong.

I'm not really sure what relevant information is needed in the selection process.  As background, I used a ground fill (copper pour assigned to GND) on all layers and this is a 4 layer board.

Also, I have already generated a soldermask bottom, soldermask top, and silkscreen top folder in the Artwork Control Form -> Film control.  In addition to those things I have etch, pin, and via information for each of the layers in the film control tab.  I'm using PCB Designer 16.5.

 Thanks!

    You can't change the plot mode in the Artwork control any more, you get a "plot mode does not match <blah>", or something like that if you try to select a different plot mode. IF you use Positive Dynamic Shapes, recommended, you will get positive artwork.
