her is my 1st car mercedes 2 doors i start it with half blob made with network curves created on blue print with a minimum
control points no hood ,after i projected arch weel cut as line from top off car and puled pushed control pts to match circle cut in side view,
same as front and back lights projected as curves from front and back view ,

note: the projected curves they update on surface changes , only if the project curve is located in one place in one pice,

here if michael can do : to set distance off curve projection will help!!!,
or even better match surface to selected curves , looks like same as network surface tool !!!
