The grid and scaling system in Eagle is very powerful and easy to use. Spend some time experimenting with it. The Tutorial page you referred to shows how to adjust the grid settings. Simply set it to Millimeters, then (to do your larger outline), set the grid to about 5mm per division. After you have your large 50mm dimensions drawn in 21’st place, re-adjust your grid to 1mm per div and place the pads.
Thanks for the start; I was able to make the schematic symbol fine and save it. Now I a am trying to make the package but I do not quite understand the scaling.
How do I go about setting the scale to build a package that measure 40mm wide by 55.5mm long. With 4 round pads 1mm in dia located 2.54mm apart and the first one position 27.05mm from one end of the outline and the center line of the pad position .5mm from the edge of the outline.
I had some similar questions about the library editor the other day. Evandude pointed me to this excellent and to the point tutorial:
