This method is faster and more convenient to draw through intelligent size matching. Because your mouse operation is always within a certain range in the center of the screen, you don't have to keep clicking the options on the left side of the screen as before, which is very troublesome.

In addition to the drawing stage, smart dimensions are also useful in the later drawing review stage. When checking the error of parts, you need to open the sketch you drew before, and the dimensions marked with smart dimensions will be displayed automatically.
