I forgot to mention that the FP Designer can do Oblong through-hole pad shape to avoid pad overlap and still provide a good solder joint.

I would use FP Designer to create this part in 3 minutes.

In V2015.02 there are no 3-Teirs for through-hole.

IPC disqualified the IPC-7251 through-hole 3-Teir library system.

We are working to develop footprintmodel for SIP-4L using 2014.12 version and need to build it for Eagle, it would be great if you could help me.

this package has 1.27mm pin pitch and its terminal  dimensions (0.44 Max & 0.41 Max) mm, there are more details in package drawing in page #5 in this datasheet - www.diodes.com/datasheets/AH276Q.pdf

In this case, the Padstack wouldbe c145h85 but the issue is the Padstacks are overlapped 

What are the right padstackdimensions (for L, N, M)?
