Welcome to the forum.
Usually when you can't thicken a surface it means you have surfaces that have intersections that cannot mesh.

Read response #3. - you should be attaching a *.zip, not a *.stp
How large is the zipped file?
What browser are you using to view this forum?
I don't either.
Just save it to your local and then browse to where it is under the attachments portion at the bottom of the responding screen.
Explain what you have tried to get this surface model to a solid.
Olá.
The surfaces are open, so it will never be a solid.
You have to trim the surfaces if you want to have some kind of thikness in every surface, or close all the surfaces to have a big solid. Now, depends of what you want... but for sure... it will give some time to become a solid.
Did you find this reply helpful ? If so, use the Accept as Solution or Kudos - Thank you!

This one would probably take me several days to complete as there are a lot of open seams and overlapping seams. Also, there are some single side surfaces (webbing) that would be isolated separately and Thickened.
I am more familiar with the older Construction Environment rather than the Repair Environment, but in one of those environments is where I would tackle this surface-by-surface until I had a "water-tight" envelope. Not really a job for a beginner.
If this is a school assignment - I think I would pick another project.
