any pointers? did you do al that in 3d, or did you do it in the different views?

Here is the trick to drawing in 3d with AC, use your 3d view, the front, right, top ect views are real good for building parts, like my link mounting tabs. I draw them out flat, using lines, arcs, circles ect, then I trace them out with a polyline, the move the polyline off the original object and EXTRUDE it to the needed thickness.

Then swap over to one of the Isometric views, SW, NE ect and move or copy it, pick a base point so you can locate its 3d position, X,Y,Z write it down, now choose where you want it in the 3d realm and just add or subtract to those numbers.

Remember the XYZ quadrants change in each view to pay attention to the locator arrows or you will shoot your part out of the picture if you forget a (-) sign.. :D

Shade for clarity when making rough movements, choose 3D wireframe when doing detail.

Lost you yet?

Good, I am confused to! I never messed with the 2d, jumped right into 3d and went with it, When I drew out my frame rails I just drew Rectangles and EXTRUDED them to the thickness I needed, if you use the thickness command when you shade it will not look right... Extrude is your friend in the 3d world.

Okay going to stop for now.. I am a 1 week old with this software, don't want to dig myself into a hole...

solid works is 100000000000000x better. Then you can convert it to Catia and do F.E.A on it

seriously Solid Works is wayyyy better

Switch your coordinates from "View" to "World", and they will always be the same (been a while since I've done any 3D in ACAD, but most drafting packages have something similar).

Glad to hear it!.. since the CNC Plasma table I will use to cut all my brackets accepts .drw files without reformating, this works for me..!

I've tried at least 5 times before to get solidworks, but it never seems to work. I might try and search again...

It's now a hour or whatever later...
I have soldiworks now.... I'll mess around with it later... I hope its as good as yall say.. and easy to learn

ok, I need a little help in solidworks...
I know you can do a pipe drawing... like a tube chassis.. I was messing around with it for like 30 min, but can get nowhere... any idea how I start and make somethign 3D with piping??

In school we use "Ideas" a really nice program :) -It's about 5$ / license -It has some really wonderful tutorials.

You can export to almost every known format also.

in pro-e they have in add in called pro-mechanica that will cycle suspension and do stresses static and dynamic. but mos of these programs it is very hard to learn in a short amount of time

In solidworks, you can get the add in that will create movies. It does not do elastic deformation (oops, I bent a link/'spring/tie rod), but it will do motion in any unrestricted direction. Also, I have a friend who uses solidworks with Cosmos. Cosmos is an add in that does FEA (finite element analysis). If you apply forces in vector form (magnitude and direction) it will show you where you will fail first. I guess you also have to specify materials.

There is a program that we used in my vehicle dynamics class called Working Model 3D. It cycled your suspension and also helped you find spring and damping rates. Would be great for a full buggy build with coilovers.

I now have SolidWorks, and I was wondering if anybody has any links to already created drawings? I would really like drawings of a Jeep tub, a rollcage, and suspension stuff but I would be interested is just about any sorta related drawings. Or if anybody wants to mail me some at madmarx@comcast.net, I would really appreciated it.

Ideas is not gone, Unigraphics bought them out and the product of the 2 is called Unigraphics NX. Let me assure you a licence is NOT 5$! It's in the thousands.

Be careful if you're making any money from the use of these programs, they are very expensive and the manufacturers spend a fair amount fighting piracy. Note to Autocad users, you might not want to visit Autodesk, their products check for and if it's missing generate a cookie everytime you run it. No clue what's in the cookie.

Solidworks used to have a home edition / students edition that was full on but couldn't read or write pro-edition files. It sold for about 100$ or less.

I did the suspension study in Solidworks. I like Solidworks for the ease of Model manipulation but I think Pro/e is a better engineering tool. Here is a roll cage and coil-over I did in Pro/e.

and a tool box... http://t3jeep.com/TOOLBOX_2ND_DRW.gif

These look kinda funny because they are pictoral renderings using pro/e's Photorender. I also have a cj-5 tub that I built using pro/sheet metal.

I agree Solid works is much beter and faster to build 3d objects. To figure out Solid Works you should be able to find a online tutorial.

As far as F.E.A you can do that in Solid Works 2003.

I would think this stuff would be a waste of time on anything unless you are cutting bracketry on a CNC with them.

Just seems stupid to build a frame and full rollcage and shit cause if you can measure well enough to be able to transfer it into cad 100 % acurately (the only way it would be useful) then you could have fabbed it in REALITY in half the time.

11-14-2002, 08:31 AM

I personally think that a good fabricator that knows his/her stuff could whip out suspension geometry and a whole vehicle for that matter ten times faster than we could using CAD. I am much more proficient designer in CAD than I am fabricating and I still am sure if I had all the parts I could build it faster.

The problem with building suspension or tube chassis in 3d is you have to model all of the parts first, then assemble them and THEN make adjustments. By modeling the parts we need to reverse engineer or at least get overall dimensions on parts. I have yet to see a 3d model of an engine or tranny or a complete axle assembly.

If I had the actual parts already it would be faster to just start cutting and bending steel than to build it in the box.

The only reason to use CAD is if you are building production vehicles. For one off stuff it just is not feasible. IMHO

Tyty, for me, I just want to be able to try some ideas for a rollcage and see how they look, without spending the money for tubing and actually bending it... I bet this is the way it is for a lot of people, being able to "prototype" stuff without actually burning welding rods and bending tubing.. My friend Jimmy has built 6 rail trucks, and they look better each time, but he still finds things to change after he "eyeballs" it and fabs it in reallife. So he sells it and makes another... I don't have enough piss and vinegar to build 6 rollcages before I build one I like....

My parts will all be cut on a CNC Plasma table so the more time I spend working with it in CAD fitting parts just right will be time well spent. I know very well that the measurements on the frame are not 100% accurate probably +/- 1" in some cases but as far as the axle bracketry goes I know damn well my axle tube is 3.25" and I now what ride height I want so I can build all these parts in the virtural world and transfer them to the Jeep. I can draw and adjust all my mounting tabs and have them cut for half of what they normally cost..

And who knows, somebody may be interested in the dana 60 diff guard and link mount I am building from digitizing a gasket, then reproduction will be a snap.

Oh and its a good thing to waste your time on rather than really working.. :flipoff2:

WHERE ARE YOU GETTIN $5 LICENSES!!!!!!!!!!!!!!!
I'm guessing you're talking about the student edition, but your links refer to v9. If you can get MS 9 without having to sell your left nut I wanna know where. I hate my student edition, but not as much as I hate acad, pro/e, and sometimes SolidWorks.

For FEA, why would you want to import to CATIA?!?!?! If you're looking for point and shoot (as if that was possible and reliable), go COSMOS/Works, if you want results you can believe, try pro/Mechanica or Ansys. MHO

Try I-Deas Master Series includes a module that will not only cycle the suspension, but will give you data re. system dynamics (i.e. anti-squat). Pretty amazing suite of tools. It does 3D modeling, assembly, drafting/documentation, data management, FEA, Generative Machining (CNC), and on, and on, and on......

I actually went through EDS's in house training. I was SO impressed. I'd been a solidworks user all throughout school, I've got over 1000 hours into it. After using I-Deas, it looks like a toy. Solidworks is great for a simple ideas that requires limited analysis, but for real work and real flexibility, I'd go with I-Deas 10 times out of 10.

the reason i do it in the computer is for this reason - i am in the design / engineering department at my work and can get any thing i want cut on a plasma bed - so this way i can make my stuff look good and professional and is quicker in the end

Even though I can envision what I am gonna make, I like to look at what I am gonna make before I make it. Also when I drew my frame I found that I needed to cut angles that were odd, like 83.5*, 103* etc... Much easier for AutoCAD to figure out those angle, then it is me. Plus if you are good at CAD you can draw up a cage, or frame pretty quick. Plus it is nice to do a FEA for shits and giggles, which would be a bit tougher with a crayon drawing on a bar napkin:D

So, you have decided to just use the driver's side upper link? I saw in the other thread that someone said that it wasn't a good idea. I am still trying to figure out why/why not.....

It would save me a little time from not having to re-route the exhaust, when I finally get around to doing it.

So which CAD program should a total beginner get? I don't know what is out there but I do know that I would want to be able to build it 3d and move it at will. I also want to be able to learn it via book or tutorial. So what are my options? From what I have read Solidworks with a couple expansion programs would be good.

I don't want to hijack but this isn't good enough for a new thread either.

Get AutoCAD to learn on. IMO once you learn a CAD program it is pretty easy to pick up on any of the others. Solidworks would be great is you can get a hold of it:D

Don't waste your time on a dinosaur like autocad. I think most people could pick up SolidWorks in an afternoon. It's very intuitive. Oh yeah, if you can find a copy of autocad you can find SolidWorks, just look a little. If you still come up short PM me.
