Problems filleting this webbed rib between multiple faces

[martijnvdwoude]

Hello!

I'm trying to achieve the following "webbed" fillet. A fillet between three faces.

I have two pipes connected at an angle to each other, and have created the webbing/rib between them using a sketch and the Rib command. Now I'm trying to create a smooth fillet in that corner so everything blends together like in this example photo. But no matter what I try I just can't create these fillets. I always get errors, no matter in what order I try to apply them or with what settings (variable fillets, very small values et cetera). It seems I can only create a fillet on either one of the edges, but when I apply one on the other they all break. Is it the sharp corners or what is the problem here?

Is fillet the right tool for the job? Is there another way I can easily create smooth transitions between these edges/faces?

My project is attached. Thanks.

Put the required fillet before the 1st one you did, 

Works but no size stated, 2mm looks ugly, went for 1mm.

Might help...

Thanks! That wasn't exactly what I wanted. But I figured it out now.

I managed to get my desired result by first applying the main fillet between the pipes. Then using surface tools splitting the face of the fillet using an offset plane from the rib. Making a 3d sketch of the fillet and using Patch in that corner.
