Hi

Does the old v3 scripts work also on v4?

Thanks
Perttu

Hi Perttu,

re:
> Does the old v3 scripts work also on v4?

Yes most of them do. A small number needed minor updates because the newer script engine in v4 will throw an error on invalid script code that was silently ignored in the old v3 version.

Thanks

just one silly question ..

Can I still keep the version 3 on my computer
and use both if needed

Thanks
Perttu

@ Pertu
Of course yes ! :)
...but it's very more powerful to launch many sessions of V4 in the same time!!!
(depending of your Hard memory available! ;)

Hi Perttu, yes MoI v3 and v4 can co-exist on the same machine.

You don't need to uninstall v3 when you get v4.

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

Hello Michael!


Life's too short...too many topics on this forum :)

Could you help me?
I bought the V4 some days ago but I'm in trouble with many scripts that worked for V3.
Is there a place (inside this forum) where I can easily get all the necessary infos to get V3 scripts easily working also with V4?

I hope so.

Thanks.

Try with an Arc Circle tangent without unity but not sure you can go to the end! :)
(then make a trim not shown here)


or with the function itself...but you must enter some very small number! :)
0.0000001


and i am not sure of what and where you want fillet something!

Yes, this is the place right here. Just list which specific scripts you are having problems with and I will reply here with some information to help you.

Hi WN,

re:

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.
