Fillet Hell

[Anonymous]

A so-called "friend" of mine asked me take a look at this problem as he couldn't do it.  I'm struggling too, but I'm sure there must be an expert out there who can come up with a solution?  The attached file is a representation of the final design since he could not share his client's model with me.  The brief is to add 5mm fillets to the concave edges (2 off) and 3mm rounds to the convex edges (5 off) which all meet at one vertex.  I did manage to get it to work by adding them as selection sets in one fillet feature but the resultant surface at the vertex is not what he is after.  Any help or guidance would be greatly appreciated!

What is the desired result here?

Putting these all in one feature results in this:

Adding the concave fillets first, and the convex fillets second results in this:

Hope this helps.

Hi Jeff,

Thanks for the quick reply!  The second version looks close, but it looks like there are some non-tangent edges there?  What order did you add the fillets?

I did the 5mm concave fillets first, then added the 3mm convex edges.  Yes, that does result in a handful of non-tangent edges:

I have been unable to get other results that seem better to me.

I am not sure this is any better, but for what it's worth.

How does this look compared to what you want?

Sanjay - yours looks right to me - how did you do it?

Below are my steps.

STEP 1: 5mm fillets

STEP 2: 3mm fillets

STEP 3: fillet the non-tangent edge between 5mm and 3 mm fillets shown in the red circle below (fillet value = 3mm)

STEP 4: fillet the non-tangent edge between the 3mm fillets shown in the red circle below (fillet value = 3mm)

best regards,

Sanjay Jayabal.

Just my opnion. 

schneik's fillets are top, way much clear, either render or manufacturing it looks much better and smooth. 

As for others Sanjay's example it looks clustered for me with small slabs and for render it possibly show some kinks on surface and so for manufacturing. PS: may not be visible in the eyes as physical part.    

Also, jeff's first image looks good to me very well blended. 

Please differ my comment from judging anyone's modelling skills.
