I made something with autocad, and I want to apply for a patent for appearance and utility model. I don't know how to do it. Do you want to size it?

You can't express the patent clearly without marking the size, so mark it. When you draw a picture with CAD, you can output it as a picture. First, you can enter JPGOUT at the command line. Second, you can click File Output. The operation steps should be done according to the command prompt, provided that the position of the picture is adjusted in the drawing area to maximize it.
