Can anyone supply Cad files for the S2 Toyota Chassis ?
Just looking at possibly a new project in the future and want to see if I can get things to fit without to much “manipulation”
Happy to pay for them if that helps
Cheers
I’ve been looking for several years… No luck! No one is willing to give away their hard work I guess.
Also, having worked for Lotus (3D CAD on the V6 Exige, so having access to the native 3D CAD data), the information is hugely confidential and the property of Lotus.
You will not find anyone who will give you the 3D CAD, unless they reverse engineer if from an actual car.
What engineering school teaches “reverse engineering”?
If you want to say copying someone else’s designs, say so. If you mean taking apart something to find out how it works (because you are not smart enough to do original work) and think you can improve on it, then say so. Everything tought in engineering schools is forward thinking, predicting…there is nothing “reverse” about engineering school!
Erm, where have you been for the last 20 years?
Reverse Engineering has been common place in the industry for years (I have been using it since 1998 with a faro arm): http://www.faro.com/measurement-solutions/applications/reverse-engineering
There are loads of companies who offer this service, so not far fetched that someone might have access to a scanner and a chassis. Hell, you could even do it with a tape measure as it’s such a simple form. Just by measuring the chassis and creating a 3D CAD, you have reversed engineered the chassis. That’s what the term ‘Reverse Engineering’ means in the industry. And yes, this is been taught by universities.
There is even a wiki on it LOL
Wow. Always with the attitude 
You are not the only engineer on this forum. As Mark has said above, ‘reverse engineering’ is a commonly used and well understood term across many engineering disciplines, I’m surprised you haven’t heard of it 
To hear things first you have to listen.
It’s a primary skill in all fields of education
Fixed.
By copying the dimensions of a chassis, you have NOT engineered anything! That’s all you’ve got. Just dimensions. And I have hired companies to scan objects for me, so that I may re-engineer portions of it. It’s not a matter of not hearing, “reverse engineering” is misuse and I think it’s insulting to engineers. Just like the word “terminology”… That means the STUDY of terms and is used where just TERM should be used. I guess that it is just a longer word and makes people THINK they are more important…

Thanks Designer … I thought that would be the case but hopeful someone has created there own CAD files …
As I have only basic knowledge on this subject [ well on a lot of subjects really ] Think I will look to employ the services of a Uni Engineering Student to help me out … Might be the easiest way to get it done .
Or perhaps you could point me in the correct direction with regards to the best software to use and online education ?
Cheers
imagine it’d be pretty fast to do if you had a bare chassis to capture it with a hand scanner, question is getting hold of both items 
To scan such a large object as a chassis is NOT just software. You need a laser scanning arm that is solidly fixed to the earth for a reference plane. Then the chassis is “painted” by the laser to record all of the points, surfaces, etc. with reference to that one point. It is quite a large and expensive machine to do a chassis. That is why it not readily available. If someone scanned a chassis, it cost them a lot of money to do that and I suspect that is why it is not just handed away or posted up for free.
Someone has changed their tune. Yesterday, reverse engineering didn’t exist and now they are an expert in the field
Anyway, cph, I am not sure what your intentions are? But if you want to learn 3D CAD, my preferred package is ‘SolidWorks’. It’s very intuitive and user friendly.
However , ‘Catia’ is the automotive standard and is what I had use when working for Lotus, Bentley, Aston Martin, JLR etc.
I have used various packages (Pro-E, Autodesk, Catia), but my personal preference is SolidWorks and this is what I use both at work and home.
All these CAD packages require an expensive workstation (computer) to run them in any anger (all will load on a normal pic, but will be very slow when you start using them). So, cloud computing will be the next thing, where you operate the CAD remotely on any device, but the computing power is done elsewhere (a bit like streaming a movie, you don’t actually play the movie on a DVD machine, you just watch it displayed on any device).
I would look at Onshape: https://www.onshape.com They seem to be at the forefront you cloud computing for CAD. I have not used it, so can’t comment. But really like the idea, especially as you don’t need an expensive CAD workstation to use it, making it more accessible to everyone.
Good luck in your venture and if I can help in anyway, let me know 
Wouldn’t the problem with scanning a chassis be a degree of inaccuracy? After all, at best you will measure whatever tolerance the chassis was made to, rather than a theoretical zero tolerance specification to which the chassis would have been made to +/- any specified allowances?
Cheers, thanks for the advice … very helpful.
Have managed to to locate an Uni Eng Student who is keen to be involved and as a bonus he has spent the summer working for the company who make the engine I am looking at.
In the very early planning stages of fitting a V8 Motorcycle engine with Transaxle GBox into a 2-11 chassis … a fair bit of “discovery” to do but the prelims look promising albeit involving a fair bit of “fabrication” .
I have several other options with regards to chassis … hence the requirement to get a CAD drawing.
I had a look at Solidworks and the intro videos looks amazing as to how it works and what can be achieved.
Taking into account my "novice " ability regarding this , would you suggest that I look to purchase the Basic setup initially with a view to upgrading as my skills increase ?
My experience with software, is that cheaper versions limit capabilities that have nothing to do with the operator… Get full functionality from the start.
SolidWorks seems to be the second best 3D modelling software but easier, more intuitive to learn than CATIA.
