Miata CAD Models
Hey guys, im starting design of my two passenger build up. Basically im looking for any computer generated parts of the mazda miata. 3D is best, but 2D drawings will work.

If you guys have any, or know anyone, or have any ideas where to go I would appreciate it. (Specfically the Engine and Trans)

PS This isn't a business thing, i plan on showing the build up and design process along with plans and a complete 3D model.

I have the splitter I designed in eMachineShop CAD :bigtu:

im no help....

Loki047 10-24-2007 03:42 PM

The bump was appreciated :)

I have a fairly accurate 2d plot of the spacing between the three valve cover bolts on the driver's side where my turbo heatshield is attached, if that's any help. :gay:

good luck loki... I think you'd get the models faster sitting down in front of your car with a laptop, a set of 12" calipers, and a pallet of red-bull.

i could make you some in MS paint...

We did a CAD drawing of a CO2 pinewood derby car in the first couple weeks of my Engineering Drawing class. I guess it sort of looks like a Miata.

Found this randomly linking from the "drift" video up on M.net... (i know... how did that happen)... but anyways...


Fully cad modeled miata... track the guy down i guess.

Loki047 10-24-2007 06:05 PM

I think thats done in a modeling program like 3d studio max or something. And it appears to be just the body. I'll give it a shot though its a start. Thanks split time.

SamS 10-24-2007 06:06 PM

I believe Joe and I deserve thanks as well. :nono:

For those who lack AutoCAD and can't look at SamS' entry, here it is rendered in .GIF format:


Incidentally, Sam, you modeled a Pinewood derby car in AutoCAD. You are a GEEK.

Next you'll tell us that you used a CNC milling machine to produce the finished product. :cool:

SamS 10-24-2007 06:18 PM

:hahano: It was an assignment in my engineering drawing class.

I haven't even gotten to use CNC yet :td:, hopefully after my SolidWorks class next semester.

Hmmmm. Perhaps you can manage a lab assignment that involves modeling and then milling a few Hayabusa-based V8 blocks with Miata bellhousings? :bigtu:

Pretty cool you learn solidworks, they teach us Pro-E instead. My teacher said the reason for doing so was because if you can learn Pro-E, then you can teach yourself solidworks. Haven't used it myself though. They integrate Pro-E into the Rapid Prototyping class, cool stuff.

Loki047 10-24-2007 06:45 PM

CNC's suck, although I did get to see a prototype V-10 milled from a solid billet :)

Water jets rock

I learned Pro/E in school and solidworks on my own. Pro/E is just a bad program, simple as that. The analytical tools are supposedly better.

Solidworks may have a "pretty" GUI, but the matrix formulation of most of their built-in elements is garbage...shear locking, overly-linearized boundaries, inaccurate "rounding" of internal node dilatational strains, auto-meshing that misses stress concentration locations, blah blah the list goes on.

When people come to me with stress issues in developped parts that end up having problems and show me a solidworks model indicating problem-free, I refuse the job. By making it so "easy-to-use" and auto-this, auto-that, the chances of getting reliable information is ridiculously low.

Solidworks is nice for quickly creating non-critical structures. Our mechanical designer uses it on all of our current products, which are built from a combination of punched and folded sheet aluminum, aluminum extrusion with finish-machine operations, and cast plastic resin with press-fit threaded inserts. None of it has to bear serious structural loads, it just has to screw together properly and look pretty.

It's very convenient that they make a free viewer for it that allows you to look at the object with full shading and layer transparency controls on any PC.

I wish I could remember where the link was, but I saw a video a while back that started with a huge block of solid aluminum being loaded into a CNC mill, and at the end of the video all the surplus material had been cut away to reveal the perfectly formed V8 engine block (complete with water jackets and oil galleys) that had been trapped inside. Can't do that with a waterjet.

True, very true.
