Hi, I would like to understand how the metal exposure is defined. For example, the highlighted white area in the picture are the pads that I would like to let the metal exposed on them for soldering (They are defined as pad in the layout editor). But I am also confused because the pad and the wire in the layout editor both are drawn using "TopLayer". How could the process tell the difference between the pad and the wire? (Pad with metal exposure and wire without metal exposure)? Thanks.![White area are the pad and I would like to let the metal exposed][1] [1]: /editor/20160629/5772fad181122.png
