How can I fill the space between multiple fills?

Unshelled

I'm wondering how I can fill in the space between this geometry in order to make it completely solid. Any suggestions?

The Enclose feature works, but the Fill command will also make a solid if it creates an enclosed volume. In your case it didn't because you have a lot of separate surface bodies, but if you make each fill feature "Add" as you go, it should make a solid. You'll be able to tell because you'll see "Surface 1" (or whatever) disappear from the Surfaces folder and you'll see "Part 1" appear in the Parts folder. You can also confirm with a section view (shift x)

Use Fill while selecting these lines

Thanks for the response, but won’t that make the shape hollow? I want to completely fill in the shape for 3d printing.

Solved: I needed to use the enclose feature.

Thanks!

BTW, You can also use Boolean Add with a bunch of surfaces and it will create a solid, but I have found some edge cases where Enclose would work more reliably.
