I would be surprised if they didn't manually accept them, but it is a bit strange they don't mention it on their website. I'd be very surprised if any of these companies they list are willing to give project files for manufacture. I assume they do this because smaller companies and hobbyist see it as more convienient, and to CircuitHub it means less mistakes / time dealing with the customer when they generate their own outputs.
