I am new to OpenCascade and wondering how I can build a solid model from 3d face model.
Suppose I have a bunch of 3d faces that enclose a volume. Those faces are not related to each other so basically they just look like a "solid" but actually not.
I understand that I can build the topology using "sewing" command in opencascade to stitch those faces together to be a "watertight" face model. However, it's still not solid model, i.e., it's still "hollow" inside.
So what kind of command or approach I can use to create the solid model from a stitched 3d face model? Is there a command that can fill the enclosed face model to get a solid? Thank you very much. Any suggestions are welcomed.

A Solid is defined as a closed Shell that specifies the boundary. The closed Shell encloses the volume. What do you mean with "hollow inside"?

thanks for your reply. "hollow inside" means there is no material inside the model. Do you mean once I define a closed shell model, then it also becomes a solid model? Thanks again.

A Shell is just a bunch of Faces sewed together. If you have a closed Shell, then you can convert it into a Solid (if you do NOT do that, the Shell will still be just a Shell, even if it could define a Solid).
When it comes to visualization, a Shell and a Solid look just the same: all that is drawn are the Faces of them.
