PNUM - Don't generated automatically - Version 2.5b (1092) -

I can’t generate pnum feature automatically.
I can do it manually.

I assume you have the default set and the .lf set. Glyphs needs to be able to determine the number style of the default set.

  1. Are the default figures tabular? If max width deviation is less than 2u, it should work.
  2. To determine whether the default figures are lining or old-style, glyphs compares the heights of zero and eight.

This is a sample image of my two sets. The numbers below are the lining figures

Both figure sets are lining and proportional. It is impossible to guess what you want in pnum, so you will have to write the code yourself.
