It's not too much, but it's still good after treatment As a junior researcher, Wang suddenly found that the illustrations of the paper he had racked his brains to come up with were too scribbled, too thin and unbearable, so he decided to add another item to the skill column-drawing schematic diagram. How can the illustrations on the covers of top journals, Daniel's papers and even high school textbooks be so pleasing to the eye? Is there a magic weapon for scientific papers, such as Meitu Xiu Xiu? The answer is-no! Those schematic diagrams that look simple, smooth, pleasing to the eye and clear in logic are mostly made by full-time draftsmen, not only by one software. Often, different parts come from different softwares and are handled in different ways, because each part needs to express different emphases, some need to be realistic, some need to be exaggerated (some like photos, some like cartoons), some need different emphasis software to draw, and none of them can meet all-round needs. This is also a very difficult process.
