IIustrator is also a plane processing software, but compared with PS, it is more used to process vector graphics files. Vector graphics are composed of paths, and there are no pixels in PS to form pictures. The picture in AI will not change whether it is enlarged or reduced, but the color sense is weak and the color block is unreal.
3dsMax is mostly used for three-dimensional and rendering. , can also be used to make some simple animation.
CoreDraw is also a vector plane processing software, which is different from IIustrator in that the two affiliated companies are different. IIustrator comes from Adobe Company, and CoreDraw is a product of Corel Company in Canada. CoreDraw is also a very powerful vector processing software. Compared with AI, the weakness lies in the wide product coverage of Adobe, and many softwares can be converted to each other.
CAD is a tool mainly used to draw plane plans, and also has the function of making three-dimensional models, but it is far less powerful than 3D. CAD is mainly used in engineering drawing and widely used in industrial design.
