How is it generated?

[-Tom-Tom-]

Wrong models:

1. Gull-Wing SSOP44 => HTSSOP44 (not available)
2. El-Cap 3528-21 => Capacitor 1210

Well, I had a look at the *.ipc-file. I know you guess the device package based on the component name, and apparently the solder pad size and arrangement.
Maybe I’ve got a better idea for this feature?:
For example, for ordering PCBs with assembly on JLCPCB I use an export ULP. It generates two files with, maybe better information:
(the Footprint is named too; Value, maybe for labeling; …)

But the Best. It works without Eagle ULP and on a lot of other PCB tools too
