Every technical drawing should have a title block. Usually the title block is located in the lower right corner of the drawing. The direction of the title block should be consistent with the direction of viewing the drawing.
1The composition of the title bar
The title bar generally consists of a change area, a signature area, other areas, a name and code area, and the layout of each area has two partition forms, as shown in the figure below.

Stage mark, also known as pattern mark, is the mark of the production stage of the drawing, indicating which production stage the drawing is in. GB-T10609.1-1989 "Title Block of Technical Drawings" only mentions "fill in the production stages of the drawing from left to right according to relevant regulations". In JB-T5054.3-2000 "Product Drawings and Design Document Format" here It is called the "pattern mark". Fill in the mark of the production stage of the drawing. The mark code should be filled in from left to right according to the following regulations:
"S"——Prototype (sample) trial production drawing marking code
"A"——small batch trial production drawing marking code
"B"——Official production drawing mark code.
Fill in the first box with S and leave it blank, indicating that the drawing is in the trial production stage, and a prototype is usually made at this time.
Fill in the second box with A. This is added after the trial production is successful, indicating that this product can be produced in small batches.
Fill in the third box with B, indicating that this product can be mass-produced.
The fourth space is reserved and generally not used.
