Watch out for layer scaling on imported PDFs

I caught a junior drafter pulling in a PDF from a civil engineer last Thursday, and all his linework was scaling at 1.003 instead of 1.0. It turned a 50-foot setback into 50.15 feet on the plot plan, and that could have thrown off the whole foundation layout. Has anyone else dealt with hidden scaling errors sneaking in from imported files?

Hold up, did they catch it before the slab got poured or was it just a drafting review thing? I'm curious what kind of PDF conversion was causing that drift.

Kept the slab pour schedule, so it's now a 50-foot setback with a bonus 0.15 feet of liability.
