AI & Automotive styling

, specifically:
SKETCH → IMAGE
then
IMAGE → 3DModel

Been looking at Vizcom to take a sketch to a render

I am not clear if Vizcom output has correct perspective because in my 3/4 view sketches, the front is NOT perpendicular to the side of the body

I am also not clear if/how overall proportion can be maipulated, basic stuff like length to width, and length to height

NEXT

Is there an AI tool that could generate even basic curves from the AI artwork. I find modelling 3/4 view images incredibly challenging.
