I work in the fire trucks design. And right now I'm modeling a car in SolidWorks . The car has many angles and many round plates, others that do blend in to get round . I'm making a complete car assembly , but I am having great difficulty in fitting the pieces . I believe it to be the method that I am using . I wonder if someone can help me or know a book or tutorials to help me . What meeting are all very basic or are to animation. All the pieces I'm doing are to be made later , so what I am doing is to make 3D the way you will ride around the car. It's not just the aesthetics . I really need help! = ) And tips ... Sorry for the English, can not be written in the best way .
