According to the specific situation, there will usually be about 3 waves of sketches. For small products, it will take 2-3 days, and for fast products, it will take 1 day to see if you know enough about the products.
That's about the same. I think you have a good grasp of the body ~ I am also useful for the products of the Luo Fei family. Yan is very online. Are they designed by their own team or outsourced?
May I ask the great god ~ how many days will the sketch time of a project take?
