First the disclaimer: I've never made a violin, and I have only ever briefly glanced at violin plans. I modeled this based on some pics I found via google. I didn't model it with F-holes so that whoever uses it can easily add those in after the fact. There's a few things that I could pick on with this surface...but there shouldn't be anything that won't sand out! Also, I haven't actually cut this...just checked it out on the PC. If someone cuts one from this, could you post pics and let me know how it looks?

You can download the IGES (.igs) file here

or the Rhino 3DM file here:
here
(you can download rhino for free if you are interested in viewing the file)

Here's a screenshot:

This is not my business, but the links don't work.

Hmmmm...that's weird. Gotta run right now...I'll have to mess with it tomorrow.

In the meantime..if anyone is interested in this file, drop me a PM with your email address and I will get it out to you.

Just right click on the link and select "save target as"...this should allow you to download it.

Happy CADing..

dang...that didn't work either.

This looks like it might work...try downloading the Rhino file here:

Parser, do you have the ability to convert that to dxf?

Thanks,

Don

OH !

And how much video memory would you recommend for running Rhino on a Mac with Fusion? Fusion is similar to Parallels, but more stable.
The MacBook Pro I'm looking at has a NVIDIA 8600 128MB card...

I'm running Rhino 3.0 on a 933 MHz machine with an integrated javascript:AddCode('URL')
Add Hyperlink32 Mb Video Card (it's an older HP machine that I bought used about 5 years ago for $250!). I'm still running Windows 2K. Rhino is pretty lightweight...you don't need anything too powerful.

I checked out the DXF conversion options and it doesn't look like I'm getting anything good out of this. Can you let me know if IGES doesn't work for your buddy?

Here's a link to the IGES file. HERE

Hopefully this works...for some reason my personal site won't allow file downloads (?)

Like Parser said, you can run Rhino on some pretty haggard hardware :)

For video memory, the more you can get the better but I would be willing to bet you'll never even approach the limits of the video hardware on a MBP. The kind of model you'd need to be working on to have an nVidia card bog down is just silly.

As for running everything in VMWare, you should give MacOS a try as your primary OS for a couple weeks and be sure you need to have it running all the time at all. It's userproof in a strange way: if it works, the user usually can't break it...but when it breaks (which might not be the user's fault) then the user also often can't fix it. Not the kind of tool I want my business depending on. XP SP2 and Win2000, at this late stage in their development, are what I'd call 'production ready' in that you can trust a properly maintained copy.

Forgive me Bob, I'm not sure what you meant...?
Please clarify...thanks!

When I got the MacBook, I was planning on doing what you're planning on doing. What I discovered (and a couple friends who are media professionals tell me this isn't so uncommon) is that MacOS is great fun as an OS, but it's too unreliable to bet your business on. I've had Apple updates go awry, applications completely lock up the OS, and some other nastiness happen and all of it is stuff that caused business downtime. So MacOS was not going to be running underneath anything my business depended on.

I wouldn't run Vista on my business PC, either, as it's young and buggy and unproven. XP and Win2000 are both at a late enough stage in their development cycle that they're rock-solid and you can trust your business to them assuming you don't screw them up yourself. I've had Win2000 PCs running for 3+ years straight without an operating system lockup or crash, and I've had no OS-related crashes on my production XP systems in years as well.

Now I understand. Yeah, I'm getting XP Pro for running all my CAD/CAM stuff and Mach. I'll probably just boot up in XP Pro for that stuff. It doesn't cost anything to do that either.

Hey Bob, that sounds unusual to me. When I was in college, we did all
kinds of live recording through powerbooks and never had a problem.
I've never had a single crash on my powerbook since I got it 2002. I
didn't even shut it down for a period longer than a year once. Have you
taken it in to have the Apple guys look through it?

James,

Folks on both sides of the "I'm a Mac, I'm a PC" war have had neagative/positive experiences with the other side. You have to take some of it with a grain of salt.
That said...
Every single solitary person I know who is a Mac user claims nothing but great things, stability in the OS, and flawless operation. No viruses, no hitches, no crashes. No blue-screens-of-death.

Some PC folks with the better OS's (XP Pro, 2000 Bus) also feel that their OS is very stable. My guess is that eventually Vista will join the ranks as people start moving to that in the PC world more.

The reality is that certain kinds of software are written to work on the OS that their particular market prefers. Graphic designers and such prefer Mac, and wouldn't ever consider a PC. Technical folks, and office workers use PC's because the software that was developed for office environments from MS and others grabbed the market early.

It's interesting how there's a "culture" that has raised up that divides Mac users from PC users. I told a friend yesterday that I'd bought a Mac, and he emailed back saying I'd shortly be hanging out at "the trendy coffee bars with your iMac and white headphones, acting all superior to us lowly PC owners." He probably figures I'll be wearing shorts and sandals or something too.

Hah! I don't even like coffee. Figures he was wrong. He's a PC user. I'm a Mac.

They were both known issues, I checked the Apple forums when they happened and there were others with the same issues.

I'm not a 'PC' person or a 'Mac' person. Windows and MacOS are both terrible in their own, unique ways. I'd be running Debian on everything if I could run my CAD/CAM software natively. Having no love for either side, I recommended the least terrible solution. If people expected the same level of reliability out of their computers that they expect from their (non-domestic...) cars then things would be different.

Hey Parser,

Joe, the guy who needed the file was able to download it, and passes on his "thanks" to you for your eforts.

Don

Cool, I hope it works for him. In looking at it..maybe I'll tweak the front view. It looks too "peaky"..I'd like it to be rounded more.

My mom plays violin, I'd love to make one for her one day!
