It is possible to design CAD models techniques in CATIA( https://www.cadcam.org/catia-modeling-techniques-of-cad-cam-services/ )using a combination of the above modeling techniques. However, this does not happen often. CAD/CAM services would generally pick a suitable modeling technique to create CAD models in CATIA based on product or part they are modeling.

The original CATI name was not retained and after a certain period of time, the software had been renamed CATIA in the year 1981, when Dassault had decided to go ahead and build their own subsidiary. This was done so that the company would be able to both develop and then, sell their own branded software (and along with that its accompanying technology). This also included the Catia Models library at that point in time.
