Which footprint format should I download and how do I import it to my footprint library? (copy paste into 'New Footprint" designer form??
Altium
Circuit Studio
Design Spark
Eagle
Easy PC (most obvious choice)
eCadstar
CR 8000/5000
I created one from Mfr's PDF which showed no locating pin hole while Snap Eda's image seems to have one.
Would like to try it.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
