How to convert a shell part to a solid Part

Hello everyone, I imported a step file (plain weave geometry) from TEXGEN into Abaqus, it came into ABAQUS as a shell part with a mesh. I wanted to do two things that have been difficult, they are:

1. Remove the mesh that came from TEXGEN

2. Change the part from a shell part to a solid part

I appreciate any help on how to go about doing these.

THANK YOU
