Hi Jessica,
We don't run Autocad here, but let me go next door to the architects. I'm sure they run Autocad, and see if they can open and convert .eps. If so, I'll get you to send me your .eps.
From memory, there are a few subsets of .eps, isn't there. Flattened, layered, CMYK ? I personally haven't used .eps for a while. Most of our stock in trade is either .psd or flattened jpegs etc, etc. How big is your .eps, byte wise ?
Speak to you soon.
Be safe, well and happy
Lotsa huggs
Catherine
