I previously sent the sketch of this car that I drew up. Then I began to create its surfaces in the standard section (nurbs) but faced a problem. The problem was some creases between those surfaces that were visible in the light ( using plastic material), while I expected a perfect integrated skin without any unwanted creases, whatever I manipulated the curves the result was the same.
I inevitably used sub-D because I didn’t know how to rearrange the surfaces in the nurbs to remove those annoying creases and attain a whole smooth body.
Anyhow, this is the car body I created in sub-D.
