Reports electrically unconnected pads (in the same layer) closer than pp_spacing.

Purpose	Close pads may bridge during imaging, etching, plating or soldering, and result in a direct short.
Function	Reports electrically unconnected pads (in the same layer) closer than pp_spacing. Measurements are segments, provided they only touch copper at its end points. If classify_pad2pad=yes, the measurements reported are only between pads that are both non-drilled and non-SMD. If no, all measurements are reported here. Does not report measurements involving features with attribute Copper Feature Ignore. If the job was created directly from a CAD database, extra functionality is provided. A measurement between pads of the same CAD net, even if unconnected in the same layer, are placed in the ‘CAD Self Spacing’ category rather than the ‘Pad to Pad’ category.
