Thank you! I think you're on to something. None of the Zoom options display the document well but I am realizing that it's due to the original size of 36x24. I tried using Laserfiche Snapshot and selecting Shrink to Fit. That worked well, hopefully the Engineering team is supportive of this approach for retaining the document.

All of the display options should preserve the original aspect ratio. The "Fit to Width/Height/Window" options control how the desired zoom level should be determined, but once a zoom level is determined it should be applied to both the x and y direction in the same way, i.e. there shouldn't be any squishing. That's why I think the problem was introduced when the page was generated.

That's supported by your report that using Snapshot avoids the problem - Snapshot is an alternate method of generating image pages from the pdf, but in general the pages generated by the two methods should be largely similar. That there is a noticeable difference suggests the the first method didn't properly generate pages.
