This is a problem. This potentially blows the whole approach to numbering
patterned parts.
And it's going to be more of a problem in the future, as we get more blank
parts with ID numbers of 5 digits (or more).
For now, I think we need to stick with 2-digit pattern IDs for these
pieces. Read on, and I'll outline why I think that's the way to proceed.
Pattern part numbers are made from three elements: the base number, the
'p', and a unique 2 (or 3) digit pattern number.
The base number and the constant 'p' are fairly critical to this approach,
assuming we want to be able to relate plain bricks to their patterned
counterparts. So we can't drop or change the base number + 'p'.
And, as Franklin points out, we have to stick to 8+3 DOS filenames. So
keeping all three elements is not an option.
If we change the pattern numbers for these face-pieces, that blows the
emerging organization of pattern IDs. That would be unfortunate, but not
as serious as the other possible solutions. Especially since there are few
face-pieces right now.
Longer term, we are going to need a different, better solution for this.
Anyone have any suggestions?
