Smooth surface from hard curves to rounded curves

[glassrobot]

Hi,

I’m trying to create a smooth and rounded surface from a hard edge to a much more rounded edge, but it seems to be past my skill set. Specifically at the top and the bottom middle of the letter “M”. I also need the solid shape to match the bottom outline curve exactly as it will be fitted into and custom armature. I’ve managed to get the bottom left of the letter to look the way I want using a variable fillet (although geometry could be better). I tried that for the other areas but it still leaves some harder edges than I would like. I’ve tried using sweep 2 rail and curve network with various curves but nothing seems to produce the desired result. Curve network is close but im still have continuity issues and getting all the surfaces to join correctly. Is there an easier way to go about this that I’m missing or are there some complex surfacing techniques anyone can share?

Thanks

i would recommend to to it with subD

a very fast sketch

make sure you have 2 stripes of planar faces (blue) at the top.
and a nice loop (green) along the edge.
use reflect for symmetrie.

for the lowest part, that has to fit an existing surface:
_toNurbs
and then bridge it with a _blendSrf

this workflow will allow you most freedom to fiddle around to find a nice blobby form.
…

EDIT
… more like this… ?

not sure if you get lucky with crease subdcrease
as soon as the upper area fits do one more subdivide and fiddle the edges:

after ToNurbs replace the lowest Face-loop with _blendSrf

above, initial workflow is named paper doll by @theoutside
you will find some tutorials of him.

kind regards
tom
