Can you make a solid body from surfaces
Can you make a solid body from surfaces
(OP)
I tried to make a solid body from a set of surfaces today and had no luck. The surfaces are all connected and look like a solid body. I tried "sheets to solid assistant", but had no luck. It seems that it sews the surfaces and only thickens them. Is there a way to do this? thanks.

Insert -> Combine -> Sew...
...function?
Now in order for this to work you will need to have enough surfaces, without any openings, so as to form a 'water-tight' set of faces. All edges need to match other edges within the range of the Modeling Distance Tolerance.

To an Engineer, the glass is twice as big as it needs to be.

Try opening up your modeling tolerance Pererences -> modeling Prefernces -> distance tolerance
and try it again.
Can you show a pic of the surfaces?

You probably will need to have several sews in the model to properly sew it together - generally it won't work in "one fell swoop"
RE: Can you make a solid body from surfaces
Now if there are actual 'holes' or openings, you may have to sew together what you can and then create 'patches' to cover the 'holes' and openings and then sew these 'patch' surfaces to the current sewn body. Eventually, once all the gaps are closed, the holes filled and the openings patched, you WILL end up with a valid solid model.

In the View Section dialog (under the Cap Settings bar) you can turn on the cap display.
To check if it is a solid, change the selection filter to solid and see if the body highlights when you run the cursor over it.
Otherwise to check the body and highlight any openings use Analysis -> Examine Geometry and tick the box for Sheet Boundaries then select the whole sewn body. If it is a sheet body, it will show the openings that are stopping it from being a solid.

If you set the 'make corner' option you able to create a solid out of surfaces.
