OK - point taken - and based on this well-reasoned argument I am happy to go
with the pXX nomenclature.
I feel a little uneasy about the possible conflict between the first and third
usages - with the benefit of hindsight might 3626v2 have been a better name?
Also how much work is required to get rid of the fifth usage?

Good point and something which I suspect will grow to make life easier for LCAD
users (as distinct from authors). Personally I'd like to see more standard
minifig shortcuts - with arms and hands orientated to hold accessories
correctly.

Variation in the ribs inside the torso which ensure the legs don't fall off
a) no ribs
b) 4 triangular section ribs
c) an x-pattern of ribs

Well - I have definitely NOT done this for torsos, because IIRC only type b)
exists ( so maybe I should make the others !!). But do we really want the
decorated torsos under three different non-TLC part numbers?
