That’s troublesome; it’s just white text. I heard that on mobile phones, white text is visible. OD, ID, and DN are also mentioned in ASME B36.10/B36.19.

@Wang Tianze doesn’t play by the standards; he is only a user of those standard elements.

The moment I pressed CTRL+A, it felt so amazing~ Is it because of the white font? …… I really can’t tell the difference between DN, OD, and ID; I couldn’t find any source for it. Now I can learn about it*, thanks! :)
