What the different? I see in Maya, Blender, Max we can create the car, airplane, bike, but why CAD like Alias is exist for Automotive?what the purposes?
Cars are conceptualized in clay models not in Maya/Catia etc. Clay scans are then rectified for final production in ICEM. Other custom made works are doe in Pro/E or catia. Maya, Blenders are for animation content most recently they are used in architectural concepts.
Automotive parts are optimized in the range of 0.01 mm which is why Catia/ProE/ICEM.
Maya is a multimedia software, but other cad software like solidworks are use to create the things which are based on the principle of physics. i mean to say the think you made in solidworks can made in actualy world , but in maya you can make water , but in actual world you can not make water,
