What does CAD drawing proportion mean?

What does this mean? I want to be in 1 now: How do I draw a picture with a ratio of 10? For example, if I draw a two-meter-long figure at 1:10, should I directly enter 2000?
my understanding: The drawings are all 1:1 when produced, so as to facilitate future document verification. It's just that the picture contains multiple windows with different proportions, and you can zoom in them.
The drawing scale refers to the ratio of the length of the line segment drawn on the drawing to the actual length.
1:100 If you draw 1mm on the drawing, it actually represents 100mm. It’s that simple.
The actual drawing is one to one, and the viewport ratio is the value written
The picture drawn on the drawing is still 1: 1 Proportion, but the picture you draw may be larger than the A3\A2 picture. In order to facilitate the display in the picture, the picture frame is scaled so that the picture you want to draw can be better displayed on the drawing.
lz understands it right, but please note that reply #2 can have different proportions in one picture.
