How to make an object hollow simply?

[Anonymous]

Hello, So I am trying to make this object hollow. I tried using offset attribute in the extrude tool but it did not help. My object went all black, maybe it is a glitch or something? Can you please suggest to me various ways I can do this? Thank you! :))

If it does go black the faces are inverted.

No that did not work either. Thanks tho 🙂 

Still looking for a solution

Hi!

By "hollow" do you mean something like deleting the top face? The object has nothing inside so technically it is hollow...

Or do you mean something else?

Hi,

I am not 100% sure what you are asking so here is a video showing how to add thickness to the mesh.

1) Delete the top face to create an open surface

2) Extrude all the faces inwards by adjusting the Z offset

3) Mesh Display > Reverse to flip the normals (fix the black surface)
