Solidworks chassis
This is not locost specific but I know these boards are active.
Is there anyway to do 1x1 inch square tubing in Solidworks?
"Structural Members" only allows for 2x2 and up.
Also, it is a hood, not a bonnet.

yes, but I can't recall exactly right now...it is easy though...it involves making a sketch and saving it as a profile

Something like this.........
To create a weldment profile:
Open a new part.
Sketch a profile. Keep in mind that when you create a weldment structural member using the profile:
The origin of the sketch becomes the default pierce point.
You can select any vertex or sketch point in the sketch as an alternate pierce point.
Close the sketch.
In the FeatureManager design tree, select Sketch1.
Click File, Save As.
In the dialog box:
In Save in, browse to <install_dir>dataweldment profiles and select or create an appropriate subfolder. See Weldments - File Location for Custom
Profiles.
In Save as type, select Lib Feat Part (*.sldlfp).
Type a name for Filename.
Click Save.

Alans got it. Or you can open an existing profile and modify that, which may be better, as sometimes one created from scratch doesnt work properly for
some reason.

Weldment Profiles
Hi all,
I am in the process of drawing up the standard "book" chassis in Solidworks using weldments. What I did was to open an exisiting profile
(i.e. 2x2), re-save it in the same folder as its new size (i.e. 1x1) and then alter the dims accordingly. It then appears in the drop down list to
use. I have found this is the easiest way to do it as it keeps all the anchor points in the right place, if you want to rotate/move a profile its a
piece of p**s

Could anyone help me on this?
When i design a certain weldment (spaceframe) and i try then to make a FEA analysis through Cosmoworks, the program tells that the part is open0body
and cannot analyse it as a single system. You can only analyze one member at once. How can i turn the weldment to a closed body and be able to analyze
it with CosmoWorks?

If i remember rightly, you need to make the weldment assembly a single part. Try saving the file as a part file. This should then make Cosmos think
its a sinlge solid body.
Will be able to check for sure when I get back to work tomorrow

Thought the same thing.
Unfortunately, the file is already a .part and you cannot change it. I converted it to .igs and then again to a .part but nothing still...

Have you added any welds to the chassis frame??? Would this make it more "solid"? Again, would have to check tomorrow

Don't you just merge the bodies into one?

you need to combine all the elements,you select all the structural members in the list on the left, and go Insert - features - Combine
also, you should switch to SW 2007 as that one has propper beam analysis that actually works..

"Insert > Features"to combine tubes... that's intuitive

The guys who do this stuff where I work, say that you can only do the fea if it has been drawn as solid bars, then 'thin walled.'
Apparently, weldments doesn't work for fea too well, at least with SW 6 versions.
Cheers,
Nev.

you are right, I did a short "tutorial" on the FEA in SW2006, it is somewhere on the site, and the only way I could do it was by using
solid bars, and then using a shell mesh, and defining the shell thickness to be the tube thickness I wanted to use... that worked ok.. but beam
analisys in 2007 is much faster..

How much does Solidworks 2007 cost? I couldn't find the price anywhere. I know it's sold through VARs instead of direct, but Solidworks
themselves doesn't list any pricing... and I'm not including a 24-month student copy.
[edit] sigh... it's very expensive, somewhere between $2500-$8000, plus about $1200 annual maintenace. So much for that.

Or there's the cracked version widely available as a Torrent, though of course this is illegal and I'd never do such a thing.
SolidWorks 2007 Torrent.
Azureus Bit Torrent Client
I have to wonder though now and again if some software companies don't deliberately turn a blind eye to this sort of thing as some sort of
undercover marketing exercise.
SolidEdge in comparison (which is what I use) has never as far as I can find been available as a Torrent or if it has it been taken down since.

pfffff 2007 is sooooo last year - get up to date 
Solidworks
2008
I definitely agree with Doug's endorsement though - if you like it and use it professionally then BUY it.

Thanks guys, but the links specifically block out access from the U.S. I can understand why...
I'm currently looking for alternatives, knowing full well what I'm going to find for cheap.

Interesting - I didn't realise that you can't access Bit Torrent sites in the US. That must cramp your style a bit You might want to
look at Rhinoceros or Autodesk Inventor as (also expensive) alternatives.
At the REALLY cheap end of the market you could try Sketchup. There is a freeware version somewhere with an option to upgrade to the Pro version. A
bit basic but surprisingly versatile.

Well I don't know about all bit-torrent sites, but the above two are locked out. I know about Sketchup but haven't tried it. I think
it's from/through Google, which is probably a good thing. I just can't believe that it can be that good for free.
Also, since I use Vista, I've run into some real problems even downloading legal trial versions. They flat-out don't work, so either
they're crap, which I doubt, or Vista is...
