Ah, you're raising a good point. I didn't go back far enough. Indeed,
there are considerations about characteristics of the part, the board,
and also the assembly process that all influence the footprint.
That's basically the design of the footprint. To the extent that such
information is available, there should at least be a way to record it
The scenario I was thinking of was that you're given a data sheet with
a footprint drawing and then you recreate that footprint in your EDA

Whee ! Shell math is for the very brave :) Bourne Shell or bash ?

Yes, there are plenty of converted libraries. What I don't know is if
people also use other EDA systems when they have to draw a new part
for use in KiCad.

No, but what I found looks interesting. Would you happen to have the
URL of the specification ?

Yup, excellent point. A parametric design helps a lot with such cases.
