i have seen many cad softwares but couldn't use those all, now i want the best software which i can use for modeling and rendering and also as i am new to these things please tell me how to design own car in cad softwares
The best software for modelling cars and such is CATIA, and the next in line is Solidworks.
You can check out youtube and search for "CATIA modelling" and youll see a few tutorial videos on how its done :)
Specialized softwares are Autodesk Alias Studio and CATIA!!
Catia & Solidworks are specialized...
the main thing is the efficiency of user... "A software is as good as the user..". if a user is able enough he can make one even in AutoCAD..
My dear fellow, your imagination and your hand is most suitable software.
You can modelling a car on your window .-))- imagine that and you will succeed.
I remeber a quote from Seymour Cray before 22 or more years when the a guys from APPLE asked him how he design a CRAY computer. He asked them on which comp you design Apple computers. They answer on CRAY. Then he answered them that he design CRAY on APPLE computers. Is'n it amusing.
The best package is the one you find yourself most comfortable with. Vertex modeling techniques will work in just about any CAD or 3D modeling package. If you're not looking for manufacturing tolerances and just want to make nice looking stuff, Blender will do just about anything and it's free. There are lots of tutorials and support for users, also. YouTube is full of videos demonstrating various modeling strategies. Different approaches suit different people. Vertex modeling is very common among Blender, AutoCAD, Maya and 3DS Max users. NURBS surfaces using splines is also an area where Blender does a very suitable job. Some people prefer to use solids modeling. GM, Ford, VW, Bentley, FIAT and many others use Alias for their surface work. I prefer AutoCAD and Alias for car modeling, both are very accurate and well suited for vehicle work.
