Something like a sequence more like this (see attached 3DM file also):



The last steps are putting in a large radius fillet here first:



Then a smaller radius fillet here:



So you've got to kind of build things in more stages and sub components than what you've been trying, and the smaller rounded areas
have to wait until the end until the larger fillets have been done first.

But these can also be some pretty difficult fillets for MoI to calculate as well, this has one of those "surfaces meet smoothly" type
situations in it where you can see the last fillet shrinks down to a point. When it's just a point at the very end of the fillet it can be
more feasible though. You may need some assistance from another CAD program with more robust fillets in it though for
this type of multiple level filleting.

Hope this helps give you more of the idea of how things are blocked out into separate pieces to start with though.

Hi Michael,
In your example, in the third shape, i can put the larger fillet but can't put the smaller.
In the fourth shape , i can put the smaller fillet.

@Finema
in the third shape Select the 2 half curves before to call the fillet! ;)

i do that but failed
have you tried ?

Hi Finema
Another way to solve your first problem (I think)

I did this with loft, mirror, and fillet.

Hi Finema,

You'll have to try a variety of different radius values, some radius values will work and others will be problematic. If you examine the very ends of the fillet when putting on the large one, you'll see some radius values leave a little wiggle in the shape at the very end, if that happens then the smaller fillets won't work although they may work on one side.

Like I mentioned above, these are some pretty difficult cases for filleting and you may need to use a different CAD program to put them in.

Thanks Michael
it's clear now

wow... thank you all so much, thank you for taking the time to explain this so thoroughly.

@Karsten - thank you very much, the thread was really useful, ended up making some faucets for practice :) Thank you!

@Michael Gibson - thanks so much Michael, this really cleared things up for me. I've gone through another few iterations, I haven't quite gotten it right yet, but being able to see the images you've posted, especially the step by step, has given me so many new ways to think about making geometry. Thank you so much!

@keith1961 - thank you so much for these... after seeing your example I couldn't believe I was ever struggling with this... you made it seem so simple :)

Thanks so much everybody, have been trying to model some more simple things to wrap my head around more tools, how and when to use them. I think I'll give this thing another try now.

Hello Volen_ck,
attached some other proposals:-)



Have a nice day
Karsten

Thanks so much everybody. Just a quick update to show my model so far. It really sped up once the weird joint was figured out. It's still not accurate and I'm making tons of mistakes, but I did manage to build something. This is a WIP and will be working on more daily modeling to get more familiar with the process.

@Karsten - this looks awesome, thank you so much, will check the file out as soon as I get back home. Very helpful to have the step by step and the file, thank you for all the help and effort!
