Can the attachments of patent applications be printed directly in 3D? I use 3Dmax, what problems should I pay attention to when intercepting and printing?

The review guide stipulates that "the instruction drawings shall be drawn with drawing tools including computers and black ink, and the lines shall be uniform, clear and deep enough, and shall not be colored or altered, and engineering blueprints shall not be used." Therefore, print with a three-dimensional diagram as long as the lines are clear. There are many problems that need to be paid attention to, but the basic principle is not to affect the understanding of drawings by technicians. For example, the section line in the section shall not hinder the clear identification of the reference line and the main line. In addition, the text in the attached drawings should be Chinese. Does "serial number" mean the page number of the drawing? Although it is not clearly stipulated that the drawing serial number cannot be marked with a signature pen, it is not difficult to avoid handwritten marking and print the drawing serial number.
