You could try making a footprint with my footprint generator in imperial mode.  The
problem here is that Altera only specifies Metric & obviously, the pin-pin spacing
still doesn't fall on every mil.

| All,
| Thanks for responding.  It looks like I have several paths to explore.
|
| 1. I was able to get IPC's website footprint generation tool to spit out a
| footprint.
| 2. Brian Gurlanick's QFP generator.
| 3. Michael Scmitt provided a footprint he uses for the Altera part I'm using.
|
| I have an additional question.  It looks like QFP footprints generally are
| created with metric grids.  Will I run into trouble when I use metric
| footprints on an imperial grid board?
|
| It seems like I remember forum posts on this issue, but I can't remember what
| the stink was about.
|
| Thanks again,
| Steve Allen
