Numbering and naming for sail triangular 6x12 modern type

[Takeshi Takahashi]

Hello,

I'm going to create part 16292 (Plastic Triangle 6 x 12 Sail with 'HLC-37' Pattern) for Friends/DP/Elves OMR project and I have some questions.
https://www.bricklink.com/v2/catalog/cat...2#T=C&C=12

The part shape is similar but obviously different to currently existing plastic sail u66 (the shoulder near the top and the hole for horizontal beam).

1. There are several print variants sharing the same cutting die, but we have no unprinted version.
https://www.bricklink.com/v2/search.page...x%2012#T=A
So I suggest as follows (u9179 is the u-number assigned to me):
u9179 Sail  6 x 12 Triangular Modern : unprinted version
u9179p01 Sail  6 x 12 Triangular Modern with Orange and Red Pattern : Part 93383 (Year 2011)
u9179p02 Sail  6 x 12 Triangular Modern with with "HLC-37" Pattern on Back Side : Part 16292 (Year 2014, the only variant printed on opposite side)
u9179p03 Sail  6 x 12 Triangular Modern with Dark Blue Wave in Circle and Dark Azure, Dark Blue and Green Markings Pattern : Part 32917 (Year 2017)
u9179p04 Sail  6 x 12 Triangular Modern with Lime and Bright Light Blue Wave and Yellow Sun Pattern : Part 1601 (Year 2022)
93383 : Alias to u9179p01
16292 : Alias to u9179p02
32917 : Alias to u9179p03
1601 : Alias to u9179p04
If there are better way, it will be highly appreciated.

2. Is the naming "Triangular Modern" appropriate? Should be more specific?

[Magnus Forsberg]

I don't think we should make any alias files. The uniqe designID should be added as a keyword in each printed part.

"Modern" might be too generic, but its hard to describe a shape like this. 
What makes this different from u66.dat?

[Gerald Lasser]

IMHO the 1601 number is the base part.

e.g. for Set 41710 (the only set which is the BI having this part), the base part 1601 comes with decoration 1019676 and it is now Material ID 6388654

The formed variant is 1019778

@Magnus and Gerald:
Thanks very much.
No aliases should be needed, I understood.

I've downloaded the BI mesh and it will be very useful.
And I've overlooked the difference of the bottom hole (93383, 16292 and 32917: single, 1601: double).
