1)The first thing to look at the structure of the drawing piece, the shape of the drawing piece should be as simple as possible, symmetrical, as far as possible a drawing forming.
2)If the parts need to be drawn many times, on the premise of ensuring the necessary surface quality, the internal and external surfaces should be allowed to have traces that may be generated during the stretching process.
3)On the premise of ensuring assembly requirements, the side wall of the drawing part should be allowed to have a certain slope
