CATIA v5/v6 has toolbars on 3 sides of the screen. Every toolbar part can be activated and moved around, snapped-in, etc like in common UIs. There are no floating windows that stay there or are there by default. But there are dialogs that open to set specific settings, dialogs are a common UI pattern as well. In v6 some of the dialogs have been replaced (made obsolete) because of the 3D editing mode. In comparision, the Blender UI doesn't follow common UI patterns at all. You can do everything you can do in Blender also in CATIA (except fluid physics, game engine) but you can do advanced simulation like finite elemente physics and electronics. Also CATIA is a CAD software, so there are of course differences and it will usually take longer to create a 3D model, but afterwards it can be built in real world with real world physics.
