i teach a few classes in solidworks

overdefintition uasloy means you have a part fully constrainted and you are tyring to add another mate

or a mate you are adding will defy a preexisting mate

Two: I realized how much work I have to do in order to make it work. The second one is kind of overwhelming, so I'm trying to push that emotion away for a while so that I can get a big enough boost from the first one.

A word of encouragement. God things never come easy, and usually take a large investment.

How do you eat an elephant? One bite at a time.

I'll keep chompin' then.

That's what makes this scenario so frustrating. I can move the parts into the position I want but the mate will not work. Even more, it worked on the other side. Here's whats happening: I added ball joints to the rear A-arms and thus needed the extra rod to constrain the toe angle. On the left side all went well. On the right side I can get everything mated except the mate that connects the toe turnbuckle to the chassis plate. If you look closely at picture #3 you can see that on left side there is a bit of an offset between the rod end and the nearest surface on the turnbuckle. The right side does not have that offset because the turnbuckle only has a concentric mate with that rod end, no coincident mate. Please help if you can.

Phew! I figured out that scenario. I ended up adding the suspension and wheel parts as a subassembly and somehow it worked. Anyway, I got the wings modeled (though I am unsure of their correctness) and did a few renders. They aren't the best but are getting better. Tell me what you think.

Looking good, I like those double wings (CDGs i think they're called)
They look from this angle to be just about right too.

Have you thought about marketing this idea?

Heresy!

The Nose is very Mclaren-ish

@Tom: I'd like to think about it but it would be extremely expensive. There are two other 1:5 scale F1 cars on the market right now, but I aim to make mine better in every way. The thing that bugs me most about the two available now is that their bodies look toy-ish so I am trying to do better.

The wings should all be correct sizes and look about how they will. I built them 1:1 scale according to regs and then scaled them to 1/5 the size. I positioned them accordingly.

@joseff: I think they look decent too. It's one of those evolving steps in F1. I'm sure people thought heresy when wings were introduced. I just hope they work like they are supposed to.

@m3_lover: I didn't specifically model it around the McLaren but I did have pictures of the McLaren up a lot. It must be a subconscious thing.

I re-read the CDG regs again and it specifies where the elements can be, so they all moved up.

Jagboy--Lovely , lovely modelling. If you would like to do your own body work...here is a little trick concerning orgami-compound-curves in resin & thick paper--90+ weight kraft paper...can be molded to shape--wetting/ steamed
with water--when dry...apply resin. This technique is actually used to build planes-- RE Section 11-13 of Understanding Aircraft Composite Construction by:
Zeke Smith Publisher Aeronaut Press, Napa California.

Basically a "male" mold plug with the paper "draped" over it...you may have to do the bodywork in several sections.

You may even speculate about building your backbone chassis using this technique. Take a moment and look at the thread about the Audi Concept car. It has a body/chassis transparency that is a variation of your design.

Really superb work. I've benchmarked this thread.

Regards Carlos

Thanks for the compliments. I'm really glad you like it.

I fixed the rear wings so that they are straight and closer together. I'll try to get some more aero bits on the body soon.

This weekend was very productive. It might not look like it, but it was. Think of the amount you get done as the graph of an exponential function: the more you get done, the harder it is to do more. A lot of what I did was touch up type stuff. I added the deans connectors with that cool little mount I designed for my Savage. I don't have wires yet because I'm not sure how to do it but they will hopefully come soon. I rebuilt the entire car as a new assembly which helped immensly: It allowed me to go over every single part and find out what I could do to make it better. A lot of the aluminum has chamfered edges which, I think, makes it look better. I added all of the fastners such as screws, bolts, and body clips. The nosecone isn't mounted yet because I havet to figure out how to make it structurally sound. There were a lot of other little things, but I think I'm starting to ramble so I'll stop. Here are some pics:

I'm not extremely happy with the renders and it's pretty frustrating and time consuming to get them right. I hope I can get some good ones this week or next weekend. One thing I can't change too much is the way the rear wings look super bright: they are mostly flat which translates into poor rendering. I'll work on it though. Hope you guys like it.


JB

Who cares about the renders. The mechanics look great - that's all we care about

I agree, but the contest requres a couple 2000 by 3000 pixel renders. I'd rather spend more time doing mechanical stuff too.


JB

Lokks great!!!!!

It looks increadable, does the nose come off? It seems kind of sad but that's something I'd look for if I was to buy a model like this, also the rear wing.
