just 2 cilinders, one 90 degrees rotated, boolean added together, it does not seem possible to fillet it. any ideas?

if I make one of the cilinders a tad smaller, it works a bit, but not to the extend that I need the fillet to be.

How about intersection of two half cylinders? Then copy bead four times? - B

I just tried that, but calculation failed.

Hi Wim - the geometry engine that MoI uses tends to have difficulty with fillets that shrink down to a single point which is what you have here.

But it seems to work better in this particular case if you only do one fillet at a time instead of all 4 at once, so I'd recommend trying that.

If you're still stuck please post the 3DM model file with your particular cylinders in it and let me know what radius you want to use for the fillet and I will try to help you finish it.

Thanks Michael, that seems to do the trick. I have the habit with filleting to take all the edges together since mostly it yields different results when doing it one by one, that is when the fillets are overlapping or touching.

thanks again!

No problem wim, I'm glad that worked for you.

Yes, normally when fillets run into each other it's better to do them all at once, especially so that the fillet engine can see that 2 fillets are running into each other and then construct a proper corner patch where they hit.

But in your particular case here since the fillets shrink down to a single point where they meet, there isn't any need for a corner patch to be created.
