not sure if the counts as a bug. i created a sphere, cut a section off, copied it, fillet the new edges, one as acis one as solid. the solid works well, the acis is lumpy on the not filleted section. when i mesh both of them the acis is not smooth whereas the solid is perfect.

Try to rotate the curve generator! ;)

It's on purpose not on the curve generator.

Hi Val, this is probably a bug in ACIS filleting, in the conversion from ACIS geometry back to Solids++ geometry.

Do you have a version of this file before doing the fillet?

- Michael

No, but it's easily replicated. if you look at the file you can see where I cut the sphere with a line. I have done it a number of times, always with the same result on the bigger section.

---

Hi Val, thanks - I can repeat it over here although it's not quite as messy as your version. It should be good enough for me to debug it though.

Thanks,

Hi Michael.
I'm having a problem with filleting the six holes on this part. The flat rear face works OK, but not the front face. The fillet size I'm applying is 1mm.

Thanks.

Can you please check which version of Moi you are running?

The front edges are working ok for me in the current Apr-13-2023 v5 beta.

Hi Martin.

It is necessary to replace the surface, for some reason it prevents rounding.

The same is true for the chamfer.

In version 4 , it can be done this way ...

Hi Michael.
It might have helped my query if I'd used the right word... It is actually a 1mm chamfer that I can not get to work on these six holes, so please accept my apologies for sending you off in the wrong direction. I'm using the V5 beta Apr-13-2023.

Martin.

HI blowlamp

You can't do the chamfer because forms are not circles and not cylinder
.
Please take a look on the next files and try to make the chamfer

Hi Christian.
Whatever you did made it possible for me to chamfer those holes, so thank you for looking into this for me.
It still leaves a mystery though, as the holes were created from circles generated by MoI.
I positioned the first circle at 12 O'Clock on the front face and Circular Arrayed the other 5. I then did a Boolean Merge to cut the holes from those 6 circles.

I just tried remaking the solid from the Revolve curves and then using 6 fresh circles from an Array. The result is still the same for me. :-(


Thanks again.
Martin.

With the file of the Start...thread
https://moi3d.com/forum/index.php?webtag=MOI&msg=11056.67
I select all the perimeters then Fillet (1mm)
Fails with the Solid++
No problem with the Ascis ! ;)

---

Hi Pilou.

Try it with a Chamfer instead of a Fillet.

Martin.

---

Hi WN.

Thanks for trying to solve this for me.
It seems like there might be a problem with where the holes are positioned on the front face. If I redo the layout, so that one hole in the group of holes is positioned at 3 O'Clock, rather than at 12 O'Clock, then the Chamfer works OK.

Hi Martin, the problem kind of originates from the Revolve, because the plane that you're drilling holes into is being created as a surface of revolution that is flat rather than as an analytic plane surface.

There is a mechanism in Revolve that is supposed to replace those surfaces with a trimmed plane surface but it does not appear to be working here, I am investigating it.

Thanks, - Michael

---

Indeed that fails with Chamfer!

---

I redraw from 0 the disc /cylinders... not on the generator curve (maybe not the root problem but more prudent! :)
(not the groove piece you can copy it if necessary...
like this all perimeters are plenty and not trimmed! ;)
So
No problem! :)

there are 2 models for make yours tests!
Solid ++ or Acis
Chamfer or Fillets 1 mm

Hello, any idea when will be full release available? Thank you.

Hi Robert,

re:

Sorry no I don't have a specific release date set yet.
