First sketches --> Now 3DS :-SS??
Hi everybody,
I've been really busy for my job but now I have some time to do some work on my personal project.
I'm drawing my first chassis in Solidworks and have been trying to draw something for the bodywork.
The car will have the possibility to remove the roof.
The windshield will be based on the GT40 windshield.
I hope I can draw some other sides of the car in the next days. After that I will have to draw it on my PC but I don't know which software I will
be using because I'm a newbie in 3D graphical stuff.
It should be able to draw sections of the bodywork and eventually also be able to convert it to a CNC file for some parts because I will be able to
use a CNC router from time to time.
Cheers,
Geoff

Like the look of that, i find myself doingmore and more car sketches these days.
you mention that you will develop a series of sections - my preferred way of gettinga starting point is to start with about 10cross sections, and loft
them, giving an open poly surface (or solid - if thesections are closed).
i use rhino, its not that easy to get to grips with, but once you're competent, you can model absolutely anything.
all the best
Tom

I have a sketch for the front.
I will make sketch from the back sometime later.
Don't forget this car will have to fit for a 6 feet 8 (203cm) tall person.
Any remarks are always welcome.
Cheers,
Geoff

The lights look too low and the front looks too busy or overcomplicated, from the side it looks just like all the others, GTM or whatever. You
don't mention the layout or drivetrain you are thinking of for it
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Thank you for the remarks. I will try to fix those issues.
The layout will be mid-engined like this forum is telling.
There are some possibilities for the engine. V8 or V12 are options. V10s are not so much available.
A Porsche or Audi transaxle will do the trick as gearbox.
If the car is done and the quality is good enough to start racing it a new engine and quaife transaxle are in the possibilities.
Cheers,
Geoff

The design looks more set out for a transverse 4 layout than lengthways V with gearbox behind it. The engine will be a long way forward into the
driver area.

This design is more than 440 cm long. If you look at the design you will see a V8 smallblock and a BMW V12 (from which I've got dimensions from
Andy) will fit in this design.
If you have a look at the Bugatti Veyron or other GT cars where big drivers can fit in, you will see the driver is sitting just behind the center of
the car.
Cheers,
Geoff

To be fair the first sketch does look a lot shorter and more elise size (& shape).
An elise is 3800mm long so your quite a bit longer, however I do agree that the driver does look a little too far back. I found it helped to visulise
the actual driver (head and bum mainly), if you do this it seems to far back.
I like the basic shape from the side although I'm not sure of the front end. It's hard to visualise what you had in mind from a basic
sketch though, so you might not be on the wrong lines.

I love the side view, the profile is definatly on track but the front view looks like a vagina
dont worry though all my car design scetches usually look a hell of a lot worse

Thanks for all the replies until now.
I have however one problem like you already mentioned. The driver sits far back. The problem is I'm 203cm tall and have extremely long legs.
If I have a further look I would be able to put the driver 15 to 20 cm more forewards but that's the most I can do.
You will find in my archive a picture with sizes for the driver. You will see I'll need like 155cm for myself whithout counting pedals space and
so on.
If anyone knows about another solution please tell me about it.
About the front sketch. I've been adding some comments to change some parts. You haven't however seen the back sketch. You can't
even see it's the back of a car. Really terrible. I will have to try it in another way.
Cheers,
Geoff

Your idea looks very similar to a Suzuki sport vehicle which used the hayabusa in a front engined design. I think this vehicle is brilliant...

Haybusa with a "big turbo" would that help?
Or go the route of the Haybusa V-8, nicer sound wicked rev's an a price to scare most schoolchildren.
I like them too very sexy, a make could do good business just reproducing them. Frame looks familiar too....
Now imagine it in hand formed polished aluminum.

If it's going to be a big car it looks out of proportion, like it will be too tall with massive tractor wheels and the driver perched high
up.

I'd agree it looks out of proportion but don't forget it is his first sketch rather than a scale drawing.
Geoff
I seem to remember you having a scale drawing of your chassis with the dimensions you need to fit, try scaling this to you sketch to see if it
matches.....
Also I gave you the basic dimensions for my chassis, have a look at my chassis pics with the seats in to get an idea of were the bulkhead has to
go.
MY bulkhead is leaning into the engine bay to give me extra room and maximise the space..... also my engine package could actually go back 100+mm as I
have pushed the engine forward as far as it could go as part of the design.
Keep up the good work.

I went to my appartment at my office place and took the dimensions I had for the base of my chassis. I will be comparing it to my sketches and redraw
them.
I hope it will look better after that.
Cheers,
Geoff

Geoff, whatever you do keep going with your ideas. I've had great plans to start designing a car similar to the suzuki but have got no more than
sketches.
Your brave sharing your sketches on an online forum like this (even thought were all friendly here).

JC,
Thank you. Sharing it at this moment is not really a problem. I'm sure the design will change a lot in the future but the basic comments are the
most important ones. The chassis is another item. I'ven been combining some very interesting things I saw on andygtt and suparuss cars. I still
have to do a lot of work on that chassis design but once I will be able to finish it.
The Suzuki is a nice piece of engineering but it is front engined and mine will be "mid"-engined.
The most important part will be the stiffness of the chassis because it will be quite big and will have to cope with a lot of power. I've been
reading about the Aluminium honeycomb on this forum and maybe I will strengthen my chassis by using honeycomb boards.
Cheers,
Geoff

I'm trying to offer helpful criticism, I think drawing is a good way to form ideas and if you ask for input, be ready for constructive ideas
even if they don't coincide with your own thinking. I like to see a bit more rounding of the sides and less intricacy in the bonnet (hood) from
the front view but that's probably not what you want. It's your car, you do as you like, draw loads more and pick your favourite.

Pete,
Don't think I'm not appreciating your comments. It's the opposite in fact. I appreciate it very much. The thing is most of the
persons on this forum have also other things to do and therefore they try to shorten their comments. I know that because I do that myself on other not
car related forums.
But like I said already all comments that has been written will have some influences in the future development of the car.
Cheers,
Geoff

Gotta say I really respect that you can do drawings of your car from your head.....
I can draw very well, but I can only copy, I just don't posses the skill to put my ideas on paper.
As Pete says do plenty of pics, its gotta be the best way to refine your shape.
