Step 2:  Select Target Package and Options

On the left-hand side of the screen, you’ll see checkboxes for each supported CAD package.  Make sure that EAGLE is the only one selected (unless, of course, you use something other than EAGLE; I don’t, so I can’t comment on support for other packages).

Next, you’ll need to set your output directory.

Click the Configuration button on the right-hand side of the main window, and select the Setup tab.  You’ll find there a list of directories, most of which you don’t care about; the only one we’re really interested in is the CAD Exports directory.  Either enter your chosen output directory here, or click the ellipsis button to the right of the entry to choose one with a standard Windows file dialog.

You may want to tinker with the other settings in the configuration dialog, but I didn’t find it necessary.

Step 3:  Generate Script and Import Into EAGLE

Next, click the big “Export to Selected Tools” button.  This will create a directory called “Eagle” in the export directory you specified in the previous step, in which it will place a new EAGLE-compatible script.  This is what you’ll use to create your parts in your EAGLE library.

Note that the scripts are named only with the date and time they were generated (eg. 2012-04-28_14-28-59.scr).  If you export multiple parts, you’ll need to pay attention, or perhaps rename them as they’re generated so you can tell them apart.  You’ll also find a readme.txt in the directory; this contains instructions for EAGLE users (which, at least on the Mac, are slightly incorrect).

And now, it’s time to import them into EAGLE.

Fortunately, it’s a straightforward process.  Simply open your target library (or create a new one), select “Script…” from the File menu, and choose the script file that Ultra Librarian generated for you.  When it finishes running, it should open the resulting device in the device editor.  Easy, right?

Of course, nothing is perfect, so there’s still more to do.
