What's the difference between CATIA and PROE?

The differences between CATIA and PROE are: different feature modeling, different intelligent capture function and different parameter association.

First, feature modeling is different.

1, CATIA: In CATIA, feature modeling is parametric modeling based on sketches.

2.PROE: PROE is often generated directly in general feature modeling, such as cuboid, cylinder, cone and so on.

Second, the smart snapshot function is different.

1, CATIA:CATIA has powerful intelligent capture function, and many constraints are automatically identified in CATIA.

2.PROE:PROE's intelligent capture function is not as powerful as CATIA, and it is quite inconvenient to define the constraints of each element very accurately by hand.

Third, the correlation of parameters is different

1, CATIA: In CATIA, all points and planes are associated with parameters, so the generated entities are highly correlated, which is convenient for future maintenance and modification.

2.PROE: In PROE, only the points and lines in the sketch have parametric correlation. In practical application, many users will mix a lot of irrelevant elements in it, which will be very troublesome to modify in the future.
