hey guys,
i want to know what computer program you guys you to design cars on, i know this has been hit before. but i am computer retarded, i meant i can autocad well and can learn other programs. i need to know what you guys use to work well, how much does it cost, and where can i get it? thanks
jason
i have done chassis on autocad but would like something that would give a better look to them, and would be easier to do.

I think you have to figure out what you want to do with it, if it's for your own personal use then Auto-Cad or Cad-Key ( now called Keycreator ) should be more than adequate. If your looking for the best designing software I'd look into Pro-E for my first choice then Solid Works, but these both are towards the higher end and come with a big $$$$.
The Pro-E I believe is the most used software in the engineering industry and one of the most user friendly.

I'm currently using AutoCAD and Solid Works. Solid Works is awesome in regard to being able to study motions, stresses, modifications, etc. I'm planning on setting up my own chassis design sometime in the near future using the full Solid Works Suit. But, down side is that it's pricey! I was lucky to get my software through work.

I use Unigraphics version 18.0, very nice and very easy to work with. I also can run Pro E, but dont have a copy of it at home. I work in Jet Engines at a Engineering company so i'm used to UG, run ir all day everyday, very boring LOL.

I would suggest Solid works for a new person to 3D modeling, seems people have an easier time learning it than any other. Pro E is a bit cumbersome at times with the constraints on the sketches etc.

I gotta question for you guys, any of you got a model, Parasolid or a IGES file of a front clip? Modeling up a chassis myself and just looking to save some time. If i got any files you could use i'd be glad to share them, i can make IGES files and or Parasolids for ya to use in Pro E or Solid Works.

Iíve been looking for a metric frame model myself without much luck to this point. If anyone has a good dimensionally correct set of 2d drawings I would be willing to create a model from them in exchange. I use Solid works but can convert to many other types of files from there.

what is your email i can give you the frame drawins that a frame shop uses.
you need to measure the frame thickness yourself at different points, but shows the lower mounting pionts, and frame marking locations, same thing a frame shop uses to bend a frame back.
it is on a 2part scanned 2d computer drawing with deminsions.

Sign me up, if it means i can look at a Modified on screen instead of a freakin jet engine.

Has anyone ever thaught of "reverse" engineering a car? What I mean by this is there is some good software out there showing RC's, front suspension and rear suspension travel to help a person dial the car in, why not take this and find the best geometry and try to design the car and build it from it?

Hey Happy, reverse engr. is what I'm planning on doing to my DW8 this winter. I already have the rear clipped sketched (on paper) and ready to model. I have an older DW4 that I'm going to us as my test ride with some of the geometry ideas I come up with. I eventually will complete the whole car and then approach it from a manufacturing standpoint (since I design tubes for mfg for a living). Hoping to get started next month as the season winds down.

I just use AutoCAD. I have experience with Solidworks and ProE. Solidworks is by far easier to learn at first than ProE imo.

For either ProE or Solidworks, you'll spend several thousand dollars per copy. ProE is very expensive. They do make a ProE student version that is under $500.

I would also be interested in any info you guys have. I am in the process of modeling everything up but it is slow trying to pull dimensions from an existing car. Maybe we can trade some files, I am currently modeling a metric chassis. Just did the critical dims for a small block ford. Next I will be modeling a powerglide. I am using Solid Works and it works fine.

Hey TG, would love to swap files. I had a whole bunch created earlier of 9" rear end assemblies, moving rotors wheels/rims, trailing arms, etc., but my files for some reason went "poof". I have to start over from scratch. For those of you using Solid Works, what revision are you on? This is real key to swaping files. I'm currently on 2004 and moving to 2005 pretty soon. Just received my update package last week. You can move upward in rev's, but can't move backwords like you can in AutoCAD, etc.

Hey Ratracer10, thanx for the drawing files. Will start using them shortly when I can devote major time to component modeling at the house again.

Will Solidworks allow you to make para-solids or IGES files ? or any other kind of exportable files ?

I got a few things modeled up in UG i could make iges files for you guys if you can read them into solidworks.

I am using solid works 2004 and can read the iges and para solid files. I am just getting used to solid works and am not sure how well it imports/ exports files, i used to use Catia v5 and UG at my last job. But so far i am pleased with solid works, you get a lot for your money.

Kromulous, yes the Solid Works can import iges and other formats. I believe the Iges is cleaner since it's an international standard. If you have some files, I'd love to get my hands on them to start building back my library. Please e-mail them to smayo964@yahoo.com. Thanx. Steve

TG, Not sure to your exposure to the full Solid Works capacity, but when you get more experienced with the software, you'll be amazed at what you'll be capable of doing.

Well i'll work with you guys to get some files together and then i'll email you the iges files to read into solidworks.

My email is on this site, feel free to email me there if you got any questions.

Also, i dont want to duplicate any effort you guys are doing so i will begin modeling a 9" ford floater assembly & links and heims.

Currently i have a body made for flat patterns and a few other odds & ends when i get to sit down and go thru it all i'll email them out.

Thanks zero for the dims

I have a shell of the metric clip including the side rails made in Solidworks 2004. I will have to make some measurements this weekend to get more accurate on the shape but I am in the process of adding the critical mounting points to it. I hope to be close to done in a couple of weeks. Also I know I have some links and heims done I will check my files to see what else I have.

My current email is Tgorsuch@adelphia.net, send me any files and i will try and open them. Let me know what you guys need for models. Thanks in advance
