HI all, sorry i havent been heard from much, but now i have a couple jobs... i got a cad job and i use UG and i have some free time now and then. I started drawing an F1 car this week, and I'd really appreciate your input. Obviously this is a big project to tackle, and i know there are many people here who can help.

Again id apreciate input(POST A REPLY,EMAIL), and even if you dont plan on helping feel free to take a gander if you like, it should be pretty cool . glad to be back

very good job. I'm very impressed!

[AndreasNystrom]

Are you gonna design the whole car in 3d, like even parts in the engine etc?
Or just the outside, and some small details, just for fun?

get a polygon-editor like www.zmodeler.com or something.. ive done a couple of F1cars in it

http://w1.131.telia....579/bt52-40.jpg for example.

Interesting to see how someone else goes about these things. Was a bit confused by the first couple of screen shots but the last ones show what you are doing quite well.

Hope you continue with updates so we can check on progress.

[Keith Young]

Yes im designing the whole car in 3d. I would at least like to get in all the body work to have something to look at, but i also want to get in as many mechanical parts as possible. Ultimately id like to make a fully working model but i know that isnt very feasable. I am not familiar w/ z modeler- do you create in mesh? what file extension does it use? etc. FW i know youve done this before so if you have any advise i am all ears, or anyone else for that matter. I work on Mon-Fri, and i get online around 10ish eastern US time. I wont get to work on the car or update daily but i will do so as often as possible. Lets make this a team effort , i cant do it as well alone as i can w/ help.

One of the biggest limiting factors will be your hardware...surprise, surprise. The most detailed one I did, the Ferrari 312T2 took ages to alter, it was just too complicated for the Hardware available.

I've also learnt that CAD programmes may not necessarily be the best choice for these things. My models seem to have improved since I moved from AutoCAD to Cinema 4D, however it depends on what you want to produce. It's going to be interesting to see how you get on with the Mechanicals...keep it up

FW

i am using Unigraphics NX(basically 19 just unreleased), and it is a VERY strong prog. I have only been using UG since june tho, so i am not fully familiar w/ it. I also have acces to a few autodesk progs like autocadr14, 2000, and mechanical desktop3 4 and 5, which i have years of experience in. So i dont think i will be very limited proggy wise. I am VERY good at mechanical parts, and i can throw in the surfaces to get the job done. My prob is i dont know the ins and outs of the car to the point where i can just sit there and draw it, im sure youve come across these things. Where do you get your dimensions FW?

That my freind is a closely guarded secret ;)

AutoCAD 14 I found hard to do what I wanted, the later releases are definately more user freindly.
Unigraphics - I'll have to look into that one.

As for the ins and outs of the cars - the Atlas photo library is a godsend - the photos are clear and large format, I've spent days just looking through them to get an idea of how the car looks.

[Keith Young]

FW-From what I gather UG has a "weak" sketcher. but they have strong 3d modeling, extracting curves, and sufacing. But UG is or has bought out ideas ive heard, which has a good sketcher, the two have or are combining which will take the best from both basically. UG will run you 20? thou without most of the licenses available. whereas autocad will run you 1? grand, and mechanical desktop will run you 5?. It is used by F1 teams if I am not mistaken, so it should do the job ;) .

What is the reference plane? is it the ground basically where the wheels are in contact or is it the bottom of the skid block?

[mulsannemike]

Just out of curiousity, has anyone tried Rhino? I have a copy, but haven't had much time to try and flesh anything out. I've been stuck having to continue on in 2D ACAD, and I have a some what well developed design, LMP that is:

The above is an early variant.

These bloddy 3D programs are not very intuitive. And with out the money to spend on proper training, you're simply left to try and figure it out.

[AndyM]

Interesting topic, great work rough_wood!

I have been busy makiing F1 bits and bobs with solidworks, the computer has nowhere near enough grunt to do more than just simple components unfortunately....

Here is a damper and spring I did, based on an Ohlins but not exact:



and here is a McLaren like steering wheel:



Hoping to add them to my site soon to improve it a bit, and have other modls on the way.

[Keith Young]

mulsanmike, i have messed around w/ rhino for a few hours in the past and i personally didnt like it. It may be a strong prog, i dont know, but the interface is so different than my way of doin things that i couldnt use it to its full potential which i predict is less than the newest versions of UG anyway. so needless to say i could hardly go farther than boolean w/ cylinders and cubes. how is rhino's surface modeling? i never got a chance to mess w/ that.

Andy, isnt solidworks an upper cad prog? i have heard of it many times so the guys at work probably have it. good work on those parts, what filetype are they? UG uses prt and can import iges step dwg dwf... thats all i remember off hand. i would at least like to throw in the suspension etc of the car. my comp should be able to do the # punching for this, i have basically the whole front assembly of the 2004 ford windstar, engine and everything. Quite a good many parts, what sucks is when i have to change a single bracket or sumthin and i still have to load the whole model sumtime, ARG!!

Does anyone else out there have access to UG or something? if you could send me components i could try to throw them in the assy.

And also how should i shape the underbody? i have a cpl pics at my site and a brief description, pls tell me if it is looking right, and also if the bottom of the skid pad is the reference plane!!! i am still looking for that before i can continue much farther. the underbody is basically on the 2nd page.

thanks for the help all, pls keep it up

1st page

2nd page

my site has limited traffic so dont bother visiting twice a day to see if i updated please.

[Keith Young]

didnt get to work on the car today (monday) so dont look for updates till tue, i should get to work on it tomorow, i basically got my projects done for the next cpl days. as soon as i got there my boss said i had a project so i busted my ass to get it all done today hehe. hopefully tue night i will have updates. till then keep up the good advice

[Keith Young]

what is the wall thickness of the monocoque?

You have got to be joking

It's alright I'm just amazed and Impressed that you are going into so much detail.

From a personal point of view, I always thought that to consider the actual thickness of the carbon Fibre parts irrelevant to the models I creat, not that I'm saying you are in any way incorrect in wanting to be so acurate, it depends on what you want to do with the completed model, but I consider that generally the thickness is not going to be noticable on the rendered article.

An exception to this in my case are the wing endplates, always look better with a thickness.

[Keith Young]

i just want this part to be a working solid and not just a bunch of sheets to look pretty.

[mulsannemike]

Tub thickness for a sports car is around 1 ". Not sure for F1, but can't imagine it would be too much different, .75"-1.0"

[Keith Young]

what do you think about my current nose?

right side view

i have it curving to a horizontal tangent at the bottom inlet of the sidepod, and its horizontal at the front wheel center line. i was wondering if i should leave it there or bring it tangent to the underbody(bring the back tangency down 50) or make it tangent to the front face of the sidepods so it has a verticle tangency. what do you guys think?

[Keith Young]

**** my bad, let me see if this works...
http://www.geocities...ough_wood/f1-14

if all this doesnt work try checkin my site tomorow, it should be in there by then id hope. itll be on page 6 or 7? right now i am working on putting it on technicalf1 so it doesnt have limited traffic.

[Keith Young]

at this point it is undecided wether or not i will put this on technicalf1, so i am saving everything on a word doc at home and ill put it up whenever i figure out where i want it.

[Keith Young]

i am basically laying off this project for a while. it hasnt found a ton of support and ive found myself very busy lately. might update later-might not.
