Hello all,
I would like to fillet the edge of my jewelry band (see pic 1) and I do that by highlighting the two edges, and input a radius of, let's say 0.5mm (see pic 2).
I have two files...they are basically the same design, except one I did it with a scaling rail.
The one with a scailing rail can do the fillet no problem.
The other file, cannot fillet the edge.

Do not understand. What am I doing wrong?
Any help out there,
Thank you,
Rudy

In the "Cannot Fillet" file it seems the maximum acceptable is 0.07.?

In the other file, the max fillet 0.78!

Brian

yes brian,
correct.
That is very small...
Thank you much,
Rudy

Hi Rudy, I'm not really sure why that one is limited to such a small radius, it looks like it should work at the radius that you were trying.

Looks like probably a bug in filleting.

One way you can work around the problem in this case is to use surface/surface filleting rather than the regular edge-based filleting.

Surface/surface filleting is where you have selected 2 individual surfaces and then run the Fillet command. It tries to produce a fillet more directly off of 2 surfaces rather than trying to follow edges which the normal one does.

Following edges tends to be more complicated and sometimes when the edge-based filleter has a problem the surface/surface filleter may be able to do it ok.

So for example in this case, take your "Band cannot fillet" object, and use Edit/Separate to break it into individual surfaces. Now select the 2 surfaces like this:




and run Fillet and then you can produce a fillet there of a larger radius, for examle 0.5:



It seems that it has some problems trimming at certain radius values even with surface/surface filleting, but there are a lot more values that work with this method.

I keep forgetting about that surface to surface. I originally reworked his curves. But this is much better.

With a .7 I saw the trimming issue you mentioned, but the fillet was nice so I deleted the missed inner surface and then just re-lofted it with the new fillet's edges.



I think I originally said something about the new fillet mechanism producing these results instead of the old "Just wont do it", but have since seen the light with it as you can get the results needed with fillet.

Hi Burr,

It will in certain circumstances, like if there are 20 fillets and one of them can't be calculated then the other ones should still get built.

Also some things like a failure to trim a fillet should not now stop it from working.

But in this case the error seems to be in constructing the fillet surface itself, and there is just that one surface to be made (if you're doing just one edge at a time) so not much to salvage in this particular case as far as error tolerating goes.

Thanks Michael.

I'm also pointing out my excitment with the way it works now.

Here's another with me getting crazy with it but results are results.

I filleted the surface to surface with "1 inch"!!! The original edges surfaces stayed there but the fillet was there under the surface. So I deleted the inner and side surfaces and had 2 fillets floating in mid air. I lofted the edges of the new 1 inch fillet with the large outside body edges and had a new model with a 1 inch fillet. It wouldnt join, seperate/join or boolean union together, so I then deleted just the 1 inch fillet surface and did a blend of the inner and outer surface and got the solid!



I know its convoluted but suffice it to say I could get a 1 inch out of the file. Hurray1

And just one more Cudos for the Gibber here.

I posted a bit back regarding filleting and solidworks and such. I'm excited to see MoI's filleter going "Past" the edges like solidworks.



Your post was that they had "Teams of people" working on their filleter over years....au contraire Mon Fraire...They only wish they had MG working there!!

As with your Mesher, I think they will be left in the dust!

"au contraire Mon Fraire"
seems must be "au contraire mon frère" ;)

Yeah I had to google it!

But you being French and all, I'll take your spelling! :)

Hi Rudy,

I've taken a slightly different approach to this problem.
Here's my version for you.

Being that you already know that you want a 0.5mm Fillet to the inside edge of your ring...
...I usually add it straight to the Sweep Profiles that I intend using!

Hope this helps, Colin

Thank you guys,
I appreciate all your effort.
Yes, Colin...I do that sometimes,....
Thank you very much to all!!

Rudy
