What software is good for 3D design and product modeling?

After PROE or UG, PROE Wildfire 2.0 and UG4.0, the difference between the two softwares has been very small. Theoretically, you can teach any course.

Proe most small and medium-sized enterprises in the south. Personally, I think PROE is the best mechanical three-dimensional software, but the genuine PROE is very expensive, so large enterprises rarely use PROE.

UG mold design module is very convenient and practical, so the mold industry is mainly based on UG, and the price of UG is moderate, so all home appliance enterprises use UG;

SW, its standard parts library is perfect and its operation is simple. More importantly, SW is cheap. Therefore, although its function is weaker than PROE and UG, it still has a place in some established state-owned enterprises. Personal development is not recommended.

3DMAX is generally used in home improvement and construction, mainly based on renderings. It is not the same type as the above three softwares.

Rhinoceros is generally used in mechanical industrial modeling design, which is powerful, but not suitable for structural design.

CATIA is widely used in aerospace, rail train and automobile industry, because the plug-in module of CATIA is especially suitable for this large vehicle.
