I need some cad help plz

Nothing real difficult, below is the side profile of the Vibe. Can anyone repost the pic with a 10 degree slope starting @ the B-Pillar. Don't hack up my car just draw a noticeable line as a reference?

Thank you ..

Here you go :



I had to rotate the picture 1.4 degrees clockwise because the car was not level in the picture. The horizontal line between the center of the wheels is to verify that the car is level.

Does this look correct to everyone else?

Remember, best not to jump straight into a 10 degree angle. A radiused transition is best.

And, according to our resident aero guru, the ideal angle can exceed 10 degrees over a certain length if you use half a 2.5 to 1 teardrop shape as a guide, eg:

(The teardrop outline is the "ideal" roof line.

Metro -

Can you apply that same shadowed teardrop graphic on top of the pic of the Vibe I supplied? Line up the highest part of the curve to the B-Pillar just behind the front doors please.

Thanks again for the help..

Here's the image rotated 1.4 degrees to level the wheels and mirrored, in case that helps :
