1. graphic requirements: be sure to draw in proportion, allowing magnification or contraction. The view is well chosen, projected correctly and well arranged. In order to make the processing patent number easy to understand and easy to assemble, the drawing is as consistent as possible with the assembly drawing, and the figure should be clear.

2. mark size requirements unified, centralized, orderly and complete. The order of dimensioning is as follows: first, the size of the main parts and the slope of the die, and then the size of the tag, and then mark all sizes. On the non main parts drawing, first mark the matching size, then mark all the sizes. 

3. surface roughness. Mark one of the most applied roughness on the top right corner of the drawing, such as mark "the remaining 3.2". Other symbols of roughness are marked on each surface of the parts. 

4. other content, such as parts name, mold number, material grade, heat treatment and hardness requirements, surface processing, graphics proportion, machining accuracy of the free size, technical specifications and so on, should be properly filled.
