LDraw.org Official Parts Library Standards: General

[Chris Böhnke]

Stud Orientation:
Missing a few words?
"The individual studs on a part should be rotated such that the stud logo appears is [like] it would [be] on the real part."

Duplicate Lines:
Feels a bit random at it's current place in the list. Shouldn't this be more along the basic rules at the top?

Header Meta Commands:
So, older relics like "0 !CMDLINE -c14" are officially gone? Should this be mentioned for older parts?

Colours:

1. "[...] but does not include the colours of paint used to decorate parts or ink used on stickers."
   It gets a bit confusing when we consider that for example 80-82 (Metallic Silver, Gold, Green) are in fact NOT available as plastic colours, but are required due to their special nature.
   
   I know this has been there for a long time, but might I take this opportunity to ask why this rule is required? And not allow for example 163 Dark Yellow in LDConfig, where it's confirmed the colour exists and has an official name and number? (Rylie Howerter: https://www.flickr.com/photos/[email protected]/).
   
   My main issue with this rule is, that I would rather see these "confirmed" cases (there's also a very common shade of greenish light blue on 1980-1997 patterns, not part of the normal palette) to use a clearly defined colour rather than direct colour. I think it would help in consistency and make certifying these parts a bit easier.
   
   As a side note, the rules do not specify colours which do exist in plastic form, but never appeared in sets (as far as knowledge goes), like "108 Earth Yellow" (https://www.flickr.com/photos/[email protected]/)
   
   
2. "In general, metallic colours on stickers, patterned parts, and other printed materials should use the LDraw Metallic Colours and not Chrome or Pearl colours."
   Personally I would prefer the Pearl colours part to be a "must not" instead of "should not", as this should not be possible to be used as ink anyways (chrome is okay in edge cases). Opinions?
