Which is better, catia or ug

It's hard to say it's good from an absolute point of view. CATIA is more suitable for large-scale projects. Our company makes molds and uses UG. I feel that UG is more convenient than CATIA in mold, but many customers (automobile companies) send 3D data based on CATIA.

Catia is not on the same level as ug and Proe. For example, catia is the United States, UG and proe are countries such as Britain, France and Europe.

Pro/E is parameterized, with rigorous modeling ideas, many reference books, many online experts, many recruitment companies, and simple parts and assembly are more convenient for later modification. Surface has style, which absorbs many free-form surface modeling methods of CDRS. More functional. Mainly used in consumer electronics industry and its molds.

UG can participate in all, participate in all, participate in all and change all, and has flexible modeling ideas. There are not too many reference books, not as many online experts as Pro/E, and even fewer recruitment companies. If you are skilled in application, it is very convenient to modify complex parts and assembly later, and you can participate in all, participate in all and change all. It is really impossible to completely transform a single part without affecting the whole.
