I noticed Through-hole Naming Convention doesn't contain an N suffix. However Surface Mount contains the suffix 'N' when using Nominal Density Level in Options.
Can you explain this point? |

The 3-Tier library system only pertains to Surface Mount footprints.  There is only 1-Tier for through-hole and we refer to it as 'Proportional' pad stacks where the pad diameter is 1.5 times the hole diameter.  ------------- Stay connected - follow us! https://twitter.com/PCBLibraries" rel="nofollow - X - http://www.linkedin.com/company/pcb-libraries-inc-/" rel="nofollow - LinkedIn |

Also, when a Surface Mount footprint uses the Mfr. Recommended Pattern or the footprint is non-standard, there is no Density Level for these footprints as they are the mfr. recommended patterns. ------------- Stay connected - follow us! https://twitter.com/PCBLibraries" rel="nofollow - X - http://www.linkedin.com/company/pcb-libraries-inc-/" rel="nofollow - LinkedIn |

So the mentioned statement means there is no suffix N in below cases also through hole, is this correct? "When a Surface Mount footprint uses the Mfr. Recommended Pattern or the footprint is non-standard, there is no Density Level for these footprints as they are the mfr. recommended patterns." |
