I said near to accurate, because Blender does no offers measurement in real life units, even if you convert them to Blender units somehow there will always be a possibility of ambiguities in calculations. more accurate they are the more possibility of you being able to making near to the accurate model.

Needless to say, they are the very basis of accuracy that you want from your model. Much before I start modeling I try to remember the shape and unique features of the car body while going through the references and if possible the actual car, this helps me to consciously identify the possible problems in the mesh while I model, of course having the reference images ready helps to solve any doubts that I may have during modeling also.

While it has been emphasized often in many car modeling tutorials, the need to gather or ‘research’ various data including photographs of cars and its various parts to help get the modeler and ready reference during modeling. Although it looks and feel like a walk though I have tried to tackle some common problems while modeling a car in Blender which I hope will be useful to another car modeler in blenderverse. What I have tried to tackle in this article is some useful approaches towards modeling the car body in blender.
