Hi WN,

re:

> The fillet tool does not work with this geometry.
> Will there ever be a fix or always use a workaround?

Actually no there will never be a fix that covers every single type of possible geometric shape because geometry comes in infinite varieties so it isn't possible to test every kind of shape. That's one of the things that makes this a difficult area for software.

But usually there are not a lot of problems in curve filleting compared to solids filleting.

In this case here it's related to the specific "anti-tangent" shape you've made.

For this particular bug a quick workaround is to use Edit > Separate and then select 2 separate curves at a time and do Fillet, followed by Edit > Join. That will avoid the bug in the corner processing for this case which I've added to my list to investigate fixing.

Also make sure that the script is the latest version.
I recollect that a few scripts were tweaked to be compatible during the early v4 beta periods...

Hi, Michael.
I asked about the corrections only for this case. Because I know that this is a pain for both you and us.
I follow this topic on the forum and try not to ask you tormenting and repetitive questions, but apparently I did not succeed.
Thank you for the proposed solution to the issue, as always, everything is surprisingly simple.

---

Ok Michael.
Thanks a lot!

Well...I've a bunch of scripts...but because right now I can't have enough spare time to devote to this task, I'm going to pospone my request.

Anyway, thanks for the help.

In the next weeks I hope I will start picking some V3 script to be fixed with your help.

See you next time :)

Hi, Michael.
Look at the file, it has a Loft for two figures.
I used a rectangle star and a Loft.

Hi WN, it seems that there is a slightly different result with one surface malformed depending on the ordering of the profile selection.

In the one on the left if you click on the rectangle first and then click on the star and then do the loft, it generates an ok result. If you click on the star first and then the rectangle second then there is one piece that isn't formed properly.

But in general a loft between curves with a different number of segments with sharp corners will not make a very good result, it's usually better to loft between smaller pieces to control which curve segments will match together. Or split pieces up so that the curves you are lofting between have the same number of segments so they can be matched segment to segment.

So in your case, maybe a reasonable approach would be to set up connections like this:


Then split the rectangle up, and join the pieces together. Then with t here being the same number of segments in each curve they will match segment-to-segment giving this result:

Michael, it was spontaneous. I thought if this is a bug, you might need it for analysis.
The pair where norm works equally well regardless of the choice, but I copied them individually.
Probably in the future, this should be ignored and achieve a good result by other means. For example, on your advice.
Thanks for the answer.

Thanks WN, I've got a fix for it prepared for v5 now.

@WN - the bug there is in the face splitting mechanism in the geometry library. I can avoid the bug by handling dividing it at creases while it is still a surface before it becomes a face with trimming boundary topology.

MoI is a very great tool. The MoI forum is simple, but the people supporting it are very friendly. Thanks for programming this great stuff. I love programming. I love MoI.
Keep working guy... Of course I bought MoI :)

yeah loft does have some odd behaviour

Hi jabber,

Can you please post the .3dm model file with the curves in it that you are lofting? Then I will be able to check if your case is also already fixed for v5 as well.

Hi jabber,

re:

Thanks - yes this one is also fixed up for the first v5 beta. That shouldn't be too far off I need to wrap up some experiments before it's ready.

Welcome, first V5 Beta

Good heavens man, you've barely had time to catch your breath after you finished the wonderful V4 release! I wasn't expecting to see a beta for quite some time, but will now look forward to the V5 beta series. Best wishes for a smooth and satisfying development process!!

Hi Larry, well for V4 to V5 there isn't going to be a big internal restructuring like there was from V3 to V4. So the v5 betas will start just as soon as I have some actual useful new stuff working.

- Michael

Great work with v4 Michael! It runs very smoothly as always.
- Is the lama mode still there? Or is it me who cant remember the shortcut?

:)

---

Rotating lamas always existing! :)
a Toggle function !
Shift + CTRL on the Options' button! ;)
