Filet not working

[andrewjohn81]

well, you'll need a bit more information then that.

With problem solving like this you'll need to provide one of three things to get good help in order of the best options first:

-an example file, or the actual file in question
-a few screenshots of the geometry in question with a good description of the problem
-a step by step providing every detail of what happens

That last options works sometimes, but for your problem I doubt that would work.

With Illustrator curves you would probably need to do some hefty rebuilding. What kind of surfaces are you building from these curves?

I think one of the biggest things to remember when creating fillets, if you want them to work the first time, is if you can create 1 planar surface do so. Many times I see something that is planar be more than 1 surface. This confuses the fillet because it thinkgs that it should be turning a corner even though it should continue on straight. I hope that makes sense.
If two things are planar make sure it is one shape. MergeAllSurfaces works most of the time. Selecting the curves and hitting planarSrf works too. If neither of those two things work then you probably have something ever so slightly off. That's a bit of a trick to fix, so let me know if that's the problem and I'll explain how to fix it without rebuilding the entire model.

I won't go any further until more info on the actual problem is provided.

Im very "green" in the 3D modeling department (in the
vocabulary, too) I'm not even sure what "planar" means!
Also this is my first post, so i cant attach files yet. Wow,
i feel hopeless, but determined. I'm away from the software now
so tonight i will study up on the planar surfaces and try
and make sense of my shapes. I'll post again so that i might
provide a file next time.
Thanks so much

Friend...
If you are trying filleting a solid then the rhino will get bad result with fillet command with irregular edge curves...

Try the following rhino fillet plugin...

nPower
Powerfillet

If it work for you... pm me i will give you something amazing thing.

Hi, Paul,
I also use the Npower plug-in for Rhino. It has saved me hundreds of hours of frustration over the past year.
Post your file, and maybe somebody can give you more specific assistance.
Good luck.

if you don't want to pay for something right now, just download the Rhino 4 alpha. It has a variable fillet tool that works almost exactly how power fillet works. I would also have to see the problem though.
The only time I haven't gotten fillets to work was because of the way I constructed the model. Of course, I usually only notice the problem when I'm nearly finished and am putting the fillets on, so it's usually too late and I have to find a way to make it work.

If you can't get the fillet to work then post at least an image of the problem area before and after the "failed" fillet. Addressing what is actually going wrong will help you construct future models. You can't just fillet any old model. It has to be constructed cleanly, with good tollerances, parameterization, and uniformity. If the design doesn't allow that, then.....well, punch the designer in the face or rethink your design. lol. OK, just a joke.

Andrew, where can one download the alpha? I can't find a link for it on Rhino's site anywhere.

thanks

The problem I run into with native Rhino fillets is that they might not be WT, or just don't work at all. And I'm not trying to put a 2mm fillet on a 1mm thick object.
When Rhino fillets work, they work fast and clean. And when they don't, I don't put 2 seconds into figuring out why. Its usually about corners or intersections of fillets not being WT.
If I have problem, I go to Npower and I'm done with it.
And the VR option is very cool.
I hope Rhino V4 works that all out.
I've not tried the WIP's as I don't have time to work through the development process. But from I've read on the McNeel NG, its coming along nicely.
Congratulations to the McNeel staff for such dedicated and skilled work.
If you need a solution today to keep your workflow going, check out Npower. If you can be patient and deal with a WIP, take a test drive of V4.
And let us know how V4 performs for you.
cheers,

I actually tried the npower one about 8 months ago, maybe it's changed since then, but when we gave it a half way difficult shape it crashed every time. Since, compared to the price of rhino, it's pretty expensive I wouldn't waste my money on it.

If you look on the main page at rhino3d.com you will notice the news section in the top right. There is usually an "update" about the rhino 4 WIP there. If not, click on the news link and you will find the article there with the download link. You DO have to have your cdkey handy I think. It's one of those keys anyway. I don't remember which one.

Hi, Andrew,
I had problems with it locking up or crashing until I got my new Rhino/C4D only box with a decent CPU and memory. I went from a 600 mghz Pentium to an Athlon 64 3800+. A very pleasant change. Rhino was also choking that old box.
There was an update by Npower last December, which you should have gotten an email about.
I agree about the price. But considering the time and headaches its saved me, its been a very good deal.
And David Gill has been about most helpful person I've ever bought anything from. I was having troube getting it installed on my new box (which is off line) and he gave me his home phone number to call him on a Saturday, if I was still having problems. How many times have you had somebody do that.......
As for V4, I just don't have the time or computer skills to deal with the problems I read about on the McNeel NG. I wish I did. I'd like to contribute to the development process. It sounds like there are some very cool additions and upgrades. I look forward to seeing the retail version.
Rhino is totally awsome, and is about to get even more so.
The other thing I like about Npower is the parametric operation. Once you get used to it (same with C4D), its a very nice way to work.
cheers,
