How to create a tunnel that is not empty inside?

Question

Blender

Tipo created a tunnel in blender, simply removing the top and bottom parts from the cylinder, how to make it not empty inside? I poked at random (for the first time in blender), I just urgently need a tunnel.

Answer 1

All 3D objects are empty inside, you always work only with the shell. I understand you need to make the thickness or what? If yes, then either extrusion

English E in edit mode, but better Alt+E then Extrude along normals

or solidify modifier

solidify

. And the question is not completely clear, it’s better to clarify, well, or try at random, as you do before)
