UG, he has CAD modules, which are sketches and three-dimensional modeling. If there is a CAE module, you can simulate the movement. For example, if you draw something in a CAD module, you can move it according to your needs in a CAE module. CAM module is a machining module. For example, if you have 3D modeling in CAD, you can generate a tool path in CAM, and then post-process, set parameters according to the machine parameters of your machining center, and then generate a machining program, so that the 3D things you draw can be shaped. There are also injection mold design module, automotive sheet metal design module, human modeling module and ship design module, all of which are good things. Learn them, and you are a talent who has to be detained. In a word, I personally think it is a good software designed and manufactured.
