I'm new to Blender and I have used the extrude tool. But somehow it doesn't go down, like creating a "void", it's like it is copying the same face again.

You can see the circle was extruded, but just don't go down.

I can't insert more images, but I want to get this result on 10:30 on this video

  • $\begingroup$ Not sure why that is happening - it shouldn't. Instead of using the extrude tool, try using the hotkeys - E (extrude), followed by the axis (Z) and then move your mouse to change the level of the surface. Does this make any difference? $\endgroup$ Jan 9, 2021 at 17:54
  • $\begingroup$ It's strange, because when I create a new project, it just work normal as it should. I think that maybe cause some sort of configuration or I have changed the proprieties since creation. And remembering this is a copy from other object. I just do it for training. $\endgroup$ Jan 9, 2021 at 18:13

..Hard to reverse-engineer what you've done, but there are a couple of clues in your picture:

  • The edges in the top surface look a little thick? There are possibly some doubled faces / vertices there. Try X deleting, or H hiding some of the faces, to see if there are more hidden underneath. It's a feature of Blender's extrude, that if you cancel by right-clicking, you don't cancel the extrusion. You cancel the move, so the generated faces remain, exactly over the originals.
  • The Gizmo indicates that something is being operated on, halfway down the bottle. AltZ go into X-Ray mode, and see if there's a face there, which is the one being extruded, out of sight.
  • $\begingroup$ Thank you. I did it. But I have created the object all over again. Somehow I I have created duplicated face and I don't know how. That's strange... $\endgroup$ Jan 9, 2021 at 19:17

    $\begingroup$ @MatheusFreitas If you start an extrusion and right click to cancel it, you're actually confirming an extrusion with an offset of 0 from the original geometry. I used to double faces by doing this all the time until I realized that right clicking didn't undo the extrusion like I thought. $\endgroup$ Jan 10, 2021 at 4:42

    $\begingroup$ @ChrisHayes .. I used to think this was a problem in the interface to extrude/inset.. but once you're used to it, it's actually useful. Like so much in Blender, IMO. a bit less 'convenience', a bit more learning, makes a better tool. $\endgroup$
