Ok so I am sick of seeing really good car design from Coventry Design students and being jealous of not being able to do it myself. So i'm going to set myself a goal to learn how to sketch a good body of a vehicle and develop myself further. Currently I am studying BSc Computer Aided Automotive Design, thinking that they would teach me how to sketch and render in this course by my 2nd year I have clearly understood that I am going to learn nothing about photoshop and nothing about how to sketch properly, @#$@#$ I should have done Transport Design, but I would have nothing to show in a portfolio. I've wanted to arm myself with the skills of being able to design in 3d Max, Photoshop, Alias, and hand sketching. As my tutors at uni are currently learning Alias themselves to teach us I don't think im going to get exceptionally skilled at it, I am self taught in 3d max using many tutorials online but really sucking at the rendering process I have nothing to show for it neither (finishing something off is a big problem for me as i consider myself to be a perfectionist and if i dont do anything correct i always get dishearted). Anyway thats an inside of wats going on within my head.

Ok so as part of one of my projects I am supposed to find a solution the design problem of a folding car, (so I have done everything that I am meant to do for it and now I have to sketch 3 sketches as part of it) I am not going to use these sketches as part of my assignment as it is going to be handed in, in a few days and i dont think im gonna get help with a click of a finger so i need to be patient but I want to use this as an example for how to design good plus the fact for this assignment I've had no help no advice and nothing to help me with the skill of drawing.

From the first picture I drew, I did not use any perspect lines, I just sketched out a few light lines and i went over it heavily. I used a HB pencil, do many of the skilled drawers use HB pencils?

So now I wanted to draw the same picture in a perspectively correct way, now I started this sketch by using a few perspective lines . I have started of the side of the car and the slant which would go into the car but as soon as i get any higher I don't think I am doing this correctly so i stopped before I go any further and have seeked help. I just dont know what lines I am supposed to follow for which part of the car

I used a 2H pencil for this it seems alot more nicer to draw with, do you guys think that is the pencil I should use?

look man, the pencil doesnt really matter if you dont know what you're doing.. i dont mean to be an ass, but theres a lot more to automotive design than just sketching in perspective. it seems you've entered into a field of CAD and dont have very strong drawing / design skills, so you may be in a spot of trouble unless you really devote every waking moment to improving.

but heres the best advice i can give you: start drawing shapes in perspective. all kinds of shapes. start with boxes, then cylinders and polygons and then combine them all to form complex shapes and rounds. then when you feel comfortable with that [which WONT be in a day or two..], go sit in a parking lot and draw every car you see from almost every angle you can..

what you REALLY need to understand, however, is the design of the car itself and how and why its formed the way it is [and its location, purpose, shape, etc.]

this is just a scratch on the surface of what you need to know.. but ill be back with some sketches and line drawings if you'd like.. - JAG

ok.. since you said you need help ASAP and have to turn in drawings ina coupl of days..here are some really crappy 30 sec. sketches.. but just to illustrate my point:

the vehicle has to be proportined correctly.. in the sense that there has to be an engine compartment, the cabin, and 'the rest'. but the weight of the car is translated thru the chassis and eventually the wheels/tires so their spacing and location are crucial to the stability of the car.

once you've established the general spacing and proportions.. you can better understand the design and can better display it in multiple angles.

that particular angle is at an angle and in perspective, yet still slightly orthographic, showing you the side and front of the car, based on points of measurement and proportion of the car. here is the perspective box i used [in blue]

those blue lines coming off the box are NOT the perspectove lines [the vanishing point is just straight off to the left..] but those guide lines helped me shape the box [just a personal thing]

the RED lines are guide lines to help me locate specific areas of the car..

my point is.. you dont have to draw the car in a complicated perspective to display it.. especially if you dont understand perspectives yet, and certainly not in your given time frame.

but this will be enough to get you thru the assignment and on to constant practising.

for a whole mess of perspective guidance.. check out these and buy a few. they'll help, i promise: - JAG

nothing to add, except that you should listen to Jag. and keep drawing...not from pictures, real things that are sitting in front of you.
