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 

[alvaro_garci]

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 for the helpful Tip!

I found another way to make your Mesh watertight.

I am using AutoCAD Architecture 2023

Change your workspace to 3D modeling

Use the Thicken command to thicken the mesh and convert to a surface.

Go to Mesh tab and convert the surface into a mesh.

Remove Creases then Close Holes

Convert to Mass Element

Then convert to a 3D Solid.
