Reply to the post of 4 10374428. It is strongly recommended to use the commercial version. Enterprises are all business editions, and most forums are business editions! After the ST edition, there is no educational edition authorization of pj! The education edition is used for teaching. He can open the education version and the business version, but only for people, and the business version of people can't open the education version ~ that is to say, if you make a model with the education version, after uploading, if we use the ST version, we can't open it directly, so you can't communicate with everyone! There are tools to turn the education version into a commercial version, but if you do this every time, everyone will feel very tired, so I suggest that if you are not a school, not for teaching, you are not a genuine education version, and you have not communicated with the education version of the school, you still use the commercial version!
