esprit in .DXF ?
Discussion
does anyone know of an accurate computer model of the turbo esprit? i'm designing a roof box for it, which interchanges with the standard roof panel. would be nice to run simulations on the computer both for aesthetics and aerodynamics. also, any input from other esprit owners regarding suggested features would be appreciated. thanks.
Don't know of one, but please let me know if you do find one. About the closest I came up with was a Japanese screen saver that has the S body Esprit (actually identical to mine, but LHD) in some type of 3D format. I never tried to conver it, but if you could figure it out, that would about do it. The level of detail is amazing. It is available here:

This goes back to my thinking of building a Stealth G body. I think it can be done. The mathmatics should be available if you research hard enough, and is all based off that Russian guy's 1920's or 1930's work on the reflectivity of RF. Original computer stealth F117 models were done in the 70's (or maybe earlier?) on the latest computers of the time. Should be a snap for a pentium. I think that incorporating those microwave traps in all the leading edges would probably reduce the signiture tremendously. Ahh, if I only had more time...

i looked at that screensaver, and unfortunately, the 3d data has been encoded into the resource. i'll have to find data on the file format, then resonstruct the file header. tedious, but nice to know this exists as a last resort . as for radio stealth, i hadn't considered that aspect, although i could certainly incorporate it into my plan. top priority for me is additional luggage space. i'm considering oddities like a functional rudder and fin for steering assist. purists may scoff, but i'm making interchangable modules, meaning i can quickchange to the original form factor.
Try this:

When you get it, it is all in Japanese. Just play with the buttons and see what changes. It is pretty cool.

depending on what cad package you are using it might be worth a shot simpy giving Lotus a call. I'm sure one of their designers could easily extract any curves from a model so as not to give you too much info but enough to allow you to work on. You never know they may be helpful and it's worth a try.

Here is the header from what appears to be a data file:
xof 0303bin 0032 Header
Mesh
+ H
and about 1/3 of the way down is the word: MeshMaterialList
and a little further: Material followed by some binary several times.
Anyone recognize the format?
Edit: It is a DirectX format. Anyone have a util to convert DirectX to DXF or any other CAD format?

I'm looking for a dxf as well - I found this but OUCH - a bit pricey :-(

i woud buy that file, except it looks quite lame. if you see a less toyish one, please let me know. maybe we can split the cost on a purchased dxf. i also know a place that'll laser scan a scale model, but then again, it'll be as toyish as the one you already found, coincidentally at nearly the same inflated cost.
I found a program called 3d explorer that will convert from DirectX to dxf. I converted all the files in the screen saver but there are a couple of issues:
1. Microsoft has an origin that is backwards from the rest of the world, and the converter program converted the files like the rest of the world. This means that all the dxf's are mirror images. Not hard to fix in CAD, but a PITA.
2. There seems to be some slight scaling issues. The files are all pieces of the final model. The body is one file, the doors and hatch are in another. When you combine the 2, the doors don't quite fit. They need to be sized and moved around a bit. Not sure if this is related to the conversion program or what. I am not a CAD person, I just mess with it.
What I suggest is that someone who is really good with CAD stuff take these files and put each file in a separate layer and scale/move around until it all fits right, then when it is together, do a mirror image on the whole thing and it will all be right. The level of detail in the screen saver program is really amazing. Even the inside window mechanisms of the door are in there. Maybe someone can come up with a better DirectX to _anything 3D_ converter. I'm not really willing/able to put the time into building a VB app to try it.

Zmodeler is free and should be able to convert a Directx model to 3DS.
look for it on goolge. Get version 1.7ish, not version 2.
I have an Esprit GT1 model, but it is only detailed enough for a game, and not necessarily accurate.

looking at your picture i think I can be quite confident that if you intend to use the model for designing something that fits to it then you haven't got a chance. That looks very much like an FEA model and a crude one at that, or a thermal model or aerodynamic model. Judging by the size of the elements on it, it is a pretty crude one at that.
