Whether building a house according to the engineering design belongs to copyright reproduction.

This problem should not be generalized. Building according to design drawings can be attributed to plagiarism. But to constitute a copy in the sense of copyright law, we must first judge the purpose of copy. If you just copy a work, it should be regarded as a copy in the sense of copyright law. Like the case upstairs, it doesn't mean that printing is not copying, just because printing is for industrial use, which has been out of the scope of copyright law and entered the scope of patent control. Therefore, this problem should be analyzed in detail, and it is really difficult to judge if the topic is not limited enough.
