There is it possible to create a drawing on the drawing station, the downloaded schema construction, and if so, how to do it?

Hi, I’m going to assume you mean the drafting station. In order to add structures to the drafting station, you need to scan the structure, and while in validation, set it to survival.
You can learn about how to do this in our discord server, in the manual chat, where you can find PDFs on how to do it
