Many short cond-lines gives a better rendering, than one long cond-line across many vertices.

Magnus Forsberg Wrote:Is it ok to place a sticker so that it is easy to place it on its brick, as long as it has (Formed) at the end of the description?
Even if it is a flat sticker?

Gerald Lasser Wrote:Does it make sense to have a formed sticker standalone in the library? If the sticker is formed (bent) then there is pretty much only one place where it can fit, on the part it was supposed to go. In my view a Part+ Formed Sticker combination would be enough.
Either this way or e.g. If it is a sticker is a stand-alone part, e.g. for the curved Wedge, it would make sense to have the sticker in its proper position when the co-ordinates of (the formed) sticker and the parts are the same.

If the sticker is just rotated, i.e. a sticker on a slope, the (relative) position for the part where it is supposed to go could be in the helpline. E.g. the Stickers for the 45° Slopes could then just be rotated 45° and positioned . In this case especially easy as all the center coordinates are full LDU values (0 10 -20)

Max Martin Richter Wrote:About the formed versions: I would like to see, if we can find an agreement, that the formed (bent not rotated) sticker is using the base coordinates of the brick, where it will be applied. (Or a moved centre coordinate if it is not applied on brick's centre.)

Magnus Forsberg Wrote:I have looked at many of complete sticker sets we have in the library.
Many of them have 1 or 2 formed stickers, but no flat version of that particular sticker.
Look at 4544258 for instance. We have all the sticker needed for that set, but no flat version of the formed f and g sticker. Why?
Must there allways be a flat versions of a formed stickers?

Gerald Lasser Wrote:I don't think the flat version shall be mandatory. Usually the flat version is where you (at least I) start from when designing a new one, so uploading it would not be too much of a hassle then. You then have the possibility to use it on other places as well.

Max Martin Richter Wrote:About the flat stickers: I would prefer, that we have a flat version of each sticker in our library. (Who tells, that nobody wants to use such a sticker on a MOC?)

Magnus Forsberg Wrote:I would say that the dimension of the sticker is not needed in a shortcut description, and that the word Sticker should be placed at the end of it.

Gerald Lasser Wrote:To refine it a bit more:
a-1: Cond-Lines An The Top Of Stickers

a-2: Cond-Lines At The Sides of Stickers (e.g. rounded corners, round stickers)
- I would say yes to this requirement, it looks like also POV-Ray makes use of them as Christophe wrote.
- It also makes the Sticker look better when primitve substitution is done,
- I also would vote for a mandatory use of the 4-4ering in rounded stickers to avoid gaps when prim-subst is done

Stil nothing on that topic?

• The description of the part should begin with 'Sticker ...' followed by the dimensions if rectangular or round, or a description of the shape, and then a description of the sticker. The description should not end with ‘Pattern’. For example:
  

• The creation of a flat version of the sticker is strongly encouraged. If the sticker is designed to be placed on the curved surface of a part or folded around the edge of a part a ‘formed’ version of the sticker part may be modelled.
  
• The part number for the flat sticker part is the SKU from the edge of the sticker sheet with a single letter suffix. Each different sticker from a single sheet should have a unique suffix. Four digit numbers should be prefixed with two zeros to avoid clashes with parts (e.g. 004845a.dat, not 4845a.dat). Stickers from sheets with combo 5-digit/7-digit numbers should use the 7-digit number. If the sheet contains only a single sticker, or multiple copies of the same sticker, then use the SKU with an 'a' suffix. If the SKU is unknown then the part number is "sXXX" where "XXX" is a number assigned by the Parts Tracker admin.
  
• The part number for a formed sticker part should be derived from the flat sticker part numbers with a c01 suffix. The part description should have a suffix of ‘(Formed)’.
  
• The sticker should be modelled as a 0.25 LDU thin box (or whatever shape sticker is in), without any edge lines (type 2 lines) and coloured with main colour 16. The sticker should be oriented such that the top face is at -0.25 Y and parallel with the X-Z plane. The pattern with the hardcoded colours is on the top face.
  
• The origin of a formed sticker part may match that of the part for which it is intended or be noted in a !HELP header line.
  
• The sticker pattern is modelled in its true colours; they are not modifiable from the outside. All printed colours of the pattern must be matched, and the background (non-printed portion) of the pattern must use colour 16. Mimicking a colour by blending in the background colour of the part underneath using colour 16 is not allowed.
  
• Conditional lines (type 5 lines), in colour 24, should be provided around curved edges and on the curved surface of formed sticker parts. Solid edges (type 2 lines) are also allowed for folds in formed sticker parts, but not around the edges of the sticker.
  
• Combination sticker/part files may be submitted for the placement of flat stickers in official sets. It is recommended that a combination sticker/part file be provided for formed stickers. The part number of the sticker/part combination should be the part number with a dXX suffix, preferably using the same scheme of codes as for patterned parts. The !LDRAW_ORG line should identify the file as a ‘Shortcut’. The name for such parts should be ‘[part name] with [sticker description] Sticker’. The dimensions of the sticker from the sticker part name do not need to be repeated. For example:

I would argue that a set of stickers is not complete unless the flat version exists, since that is how it is provided.

Does anyone else have a strong opinion on whether formed stickers should be hidden?

Quote:First point: In my eyes we should have the flat version and eventually the formed version. Part+Sticker is just nice to have but not necessary in my eyes.

Quote:Second point: Yes, I'm with you.

Quote:Third point: They should not be hidden. I really like to build the full model with each individual part if possible.

The only use I see for a flat version of formed stickers is for BOMs. But part+formed sticker shortcut could be used for BOMs, so I propose that if flat version of sticker is not provided then a part+formed sticker should be created. This is of course to prevent a too heavy burden on sticker part author for something of little use.

Note: IMHO, part+flat sticker for simple "orthogonal" parts like bricks or tiles are probably mostly useless and clutter library.

Don't agree for the above reason.

No strong opinion. I'd rather favor hidden formed sticker if part+sticker shortcut is provided (avoid clutter). Modern editors allow easy inlining of shortcuts if really needed...
