Question about aring usage in library

[Gerald Lasser]

I initially wanted to use a 1-4aring on the (transparent) Belville door 33216 due to the indents on the curved top.

Due to the missing adaptation for primsubstitution on the  48 side, I used rotated 48\1-16chrds to avoid gapes when prim sunbstitution is done

THis is the current code to fit the torus

Code:

1 16 69.5 -55.5 -2.5 0 0 -69.5 -69.5 0 0 0 1 0 48\1-16chrd.dat
1 16 69.5 -55.5 -2.5 -26.596499 0 -64.209628 -64.209628 0 26.596499 0 1 0 48\1-16chrd.dat
1 16 69.5 -55.5 -2.5 -64.20966 0 -26.59626 -26.59626 0 64.20966 0 1 0 48\1-16chrd.dat
1 16 69.5 -55.5 -2.5 -49.144145 0 -49.144145 -49.144145 0 49.144145 0 1 0 48\1-16chrd.dat
1 16 69.5 -55.5 0 0 0 -69.5 -69.5 0 0 0 -69.5 0 48\tm04o0360.dat

This creates gaps towards the torus:

Code:

1 16 69.5 -55.5 -2.5 0 0 -69.5 -69.5 0 0 0 1 0 48\1-4aring.dat
1 16 69.5 -55.5 0 0 0 -69.5 -69.5 0 0 0 -69.5 0 48\tm04o0360.dat

so from this use case I would haveexpected the following when activating prim-substitution
#1: Inner curve: fixed at 16 sided
#2: outer curve: increase resolution to fit the torus.

As #2 was not being done, I went for the chrd solution

Concerning the use cases:
#1 between a 16/48 sided prim:
-> depending on the slider it has a "filler" purpose, but once both are at the highest resolution, it can be omitted

#2 between a 48 prim and 16 sided fixed one.
-> (my intended use case) this has always a filler purpose as the 16 sided geometry does not increase, only the 48 sided needs adaptation.

I thnk there need to be some more parts evaluated that use it.
