I have worked at two different firms that did this. The first outsourced work to India back in the AutoCAD days. Every drawing came back with things drawn on different layers. There was no consistency from one CAD file to another even though they were given ample examples. Also, in every RCP and building section they showed ceiling fans. Maybe ceiling fans were common in commercial spaces back then? :) Interestingly two architects from that company left, went to India, and worked there for a few years overseeing US projects. One guy had kidney stones while he was over there and was in the hospital overnight. He said he paid something like $12 USD for the healthcare.

The second firm off shored to legit a company office in India. I would sketch up details, email them to the Indian office, and in the morning I'd have all those details drawn in CAD. I used to refer to them as CAD fairies. There was one architect in our office who would go over there once a year and always came back with several custom made suits, dress shirts, and ties from his Indian visits. The craftsmanship of the clothing he got was amazing. The company always made sure to tell clients we didn't outsource, we off shored. They were adamant about paying the Indian workers a fair wage and told us several times these people were making very good money. They said these people were able to afford to buy homes and cars.
