See this question, a face of black people ask good face,? Please ask what major does not need a lot to learn, even if it is a software, you have to practice over and over again to be able to familiarize yourself with it. Here on this topic to play on the understanding of product design it ~
First of all, to do a lot of practice is undoubtedly, why do you say so, that is because the product design is not imagined so simple and casual, but requires a lot of different aspects of the knowledge base, such as modeling software, and then for example, hand-drawn, as well as your familiarity with the material, process, structure, all of these aspects of knowledge are determined by your expertise in product design, the product design, the product design, the product design, the product design, the product design, the product design, the product design, the product design and the product design. determines the extent of your expertise in product design.
Saying that the most need to practice what it is, that is hand-drawn la, some people will think that it is just lines, straight lines, curves, do not need a lot of practice can be, sketches, just draw it. But to draw a good is not easy, I remember I have a university classmates also specialize in hand-drawing, hand-drawing classes, Mount Lushan hand-drawing, Zoll Mol hand-drawing, and so on, go to his dormitory to see him every day to practice twenty or thirty, every day, a dozen of thick paper on the table, that is, specializing in practicing straight lines, curves, drawing circles, but day after day, year after year, his hand-drawing is really cattle! I do not practice properly, hand-drawing is simply not out of hand. My classmate is now basically able to draw to the extent of the picture below. I'm not sure if it's a good idea, but I'm sure it's a good idea.
Then there is modeling, modeling is also to practice, as I sometimes want to do a surface, always draw a line drawing is not good, and then modeling to build out the surface is not good, and some people modeling to draw a line is very good, so the surface is also very good, and that is some of the complex surfaces modeling is also need to be method, if you are not familiar with the software commands, may not be able to start, modeling out of the surface may be The first thing you need to know is that you can't model a complex surface without being familiar with the software commands.
In summary, practice is very important!
