Surface to Solid watertight problems

[alvaro_garci]

Hello all,

I am trying to create a solid joining the surfaces I have but it keeps telling me "no watertight volume created".  I tried everything, making the geomtry smoother, dividing the solid in sections, but there are some that aren't supposed to be closed to get a watertight volume. I also went joint by joint checking if there are any gaps but I couldn't find the problem. 

I would appreaciate some help here

I attach the model. 

Thank you

Which ones? Lots of 'air' between your shapes

So the red coloured and yellow coloured shapes are already closed as solids. The white shapes are the ones I can't transform into solids

Try scaling the collection of surfaces, regions... up by a bit and then use surfsculpt.

For example,  I scaled the white objects by 1.1, then successfully used surfsculpt and finished by scaling the solid by 0.9091 ( 1/1.1) .  The red object is a solid.

P.S.  I forget where I learned the scaling trick.

thank you very much
