3D area program that will calculate the area of 3D objects

Hi Techyv Friends,
Does anyone know about the 3D area program that will calculate the area of 3D objects. Is there any such program that will get the display the proportional area of a 3D object. Which will be easier to calculate the exact area of the original object. Please provide me details if anyone knows about the mentioned program.
Thanks,
Ethan Jessica
