What is used to calculate the pad length on parts with inward bent leads? 

(J-Lead, L-lead, PLCC, etc.) 

As far as I can see, the software doesn't provide a field for the measurement of the inward extent of the leads on these parts. (Like L on SOPs, but inward.)

Additionally, what is E2 supposed to measure on an L-lead part?

Thanks!

The Inward L-Bend is similar to the J-Lead component family but with flat leads that bend inward. 

The E2 dimension is to the center of the terminal leads. You may have to do some math to figure that out. 

This component family and terminal lead are in the new Footprint Expert Guideline which will be released next week.
