Official Library File Format Restictions

[Willy Tschager]

Stud orientation and mirrored studs are not addressed.

IMHO concerning the part naming when it comes to dimensions, e.g. if it is 2 plates high, it will be .667, this was change in the past from 2/3 to this, I think it should be added and also how many decimals shall there be in the description (3).

Also:
anything Bricklike: Studs x Studs x Bricks
anything Technic looking: Studs x Studs x Studs

Where is the orientation of a part taken care of?

[Chris Dee]

A constant hassle for newbies is the usage of Metallic vs. Chrome in patterns. May be https://www.ldraw.org/article/512.html#ldconfig is the right place to address that in patterns only Metallic is used to represent shiny colors.

Not just newbies

[Orion Pobursky]

Code:

where a line is being used for fine detail within a pattern and that pattern is re-used within many parts (and hence sub-parted) in different colours (for example, sub-part s/973p11a.dat)

We do no longer use emphasis lines. Should be deleted.

This has already been deleted in the draft.

Code:

Extension

All files in the LDraw Parts Library are required to carry the .DAT extension.

.DAT has to be substituted by .dat. Otherwise the whole discussion will start over again at the next revision.

w.

The draft has been changed. You're still looking at the original.

[Orion Pobursky]

I still believe that the list what triggers a HOLD should be added and this:

https://www.ldraw.org/library/tracker/ref/l3pmsg/

should be deleted or updated.

This will be it's own document. I'd like it to be separate from the spec to have be more easily editing.

is how to deal with blanks in combinations with decimals as in sticker dimensions.
Sticker 3.1 x 3.1 Round

Not sure what you mean. Same rules apply, correct?

Furthermore this information should be mirrored to https://www.ldraw.org/article/339.html

This article will be cancelled and archived once the draft is ratified.

Correct. Just showing that nothing change with a decimal.

This article will be cancelled and archived once the draft is ratified.

Then the "blank" rule should be mirrored to https://www.ldraw.org/article/512draft.h...icker_desc

An example has been added to the header spec.

Also:
anything Bricklike: Studs x Studs x Bricks
anything Technic looking: Studs x Studs x Studs

Hmm. Header spec or Official Library spec?

Where is the orientation of a part taken care of?

Nowhere. Origin and orientation could be a document in and of itself.

I added some verbiage here:
https://www.ldraw.org/article/512draft.html#origin
I think it's better to write in general terms and let the individual cases be sorted out on the PT but I'm open to rewrite suggestions.

I've tweaked https://www.ldraw.org/article/512draft.h...icker_desc to reference the Header spec

Sorry I don't get it. Is it:

Code:

but does not include the colours of paint used to decorate parts or ink used on stickers.

Then it is wrong. Metallic as well as Chrome are defined in LDConfig.ldr. Problem is that pattern and stickers have to use Metallic instead of Chrome.

But there are exceptions, eg. mirror stickers that are best rendered with chrome colors...

[Orion Pobursky]

No it's:
"In general, metallic colours used on printed parts should use the drum lacquer or "ink" colours."

[Magnus Forsberg]

No it's:
"In general, metallic colours used on printed parts should use the drum lacquer or "ink" colours."

Please don't use "Drum lacquer" or "Ink". That's lego nomenclatura. We only say "Metallic" in ldconfig.

Personally I would accept all colour codes in a print, or sticker, except "Pearl", "Rubber" or "Internal Common Material".
Those codes are reserved for parts with material properties.

btw, we are IMO missing a whole section in ldconfig about flat colours to be used on textile parts, like canvas, and capes, and parts made of felt.

[Willy Tschager]

Ok, I changed the wording to be more clear

[Magnus Forsberg]

May I suggest another change.

In general, metallic colours used on stickers, patterned parts, and other printed materials the LDraw Metallic Colours (these colours are referred to by LEGO as drum lacquer or "ink") and not Chrome or Pearl colours.

In general, metallic colours used on stickers, patterned parts, and other printed materials should use the LDraw Metallic Colours (these colours are referred to by LEGO as drum lacquer or "ink") and not Chrome or Pearl colours.

The comment about drum lacquer and ink is only true on 3 of the metallic colours, silver, gold and copper. I think we should remove that parentheses.

[Orion Pobursky]

I like it. Change made.
