Alright, I'm fairly new to Blender and I'm currently following this video tutorial (Blender Tutorial: Create a Spaceship Corridor in Blender by Blender Guru) in order to get familiar with basic modelling, extrusions, mirroring etc.

At 7:25 (direct link), the guy creates a little handle for the door/structure thingy he's currently modeling. He selects a face at the lower part of the mirrored model, goes to extrusion mode (E), cancels extrusion (ESC), scales it (S) and then he decides to remove the lower face.

It should now look like this:

blender guru deleting face

However, when I follow the exact key combination (shown at the lower right of the video), I end up with that:

MFW when I have no face

Did he somehow 'extruded' the face by moving it inwards? There aren't any keys showing up that might indicate this.

I hope this isn't a stupid question. Blender heavily relies on keyboard shortcuts for efficient working and until I'm not 100% familiar with them, a lot of it is pure sorcery. :)

  • $\begingroup$ I'm not too sure why there isn't a hole in the tutorial (it's hard to say without looking at the mesh itself), but if there had been a hole his next adjustment (moving the bottom edge down with clipping enabled) would have fixed it. This is preferable to increasing the merge distance, as you don't have to worry about accidentally merging vertices that weren't merged before. $\endgroup$ – gandalf3 Oct 12 '15 at 18:33

From the video I see he's setting a mirror modifier (on Z and Y), and that the bottom edge of the face that is deleted is just on the lower limit of the vertical mirror (Z). So the geometry you see below is a mirrored face, mirroring the above face.

The "trick" should be that he has "merge" in the mirror modifier, so, I think that in his model the "deleted face hole" height is in the range of the "merge limit", so the modifier is "filling" the missing area.

If your does not, try increasing the "merge limit" until you get the same effect... (I tried with a simple plane, and with my mesh scale this happens setting a mirror merge of 0.1117)

enter image description here enter image description here Obviously it is not sane to have a "merge limit" too high, but if it works, this will confirm that it is what he did in the video.

Btw, just after that point he also set the "clipping" so that the modifier prevents him to add vertices below the Z mirror line (while he's dragging the lower edge of the lowest face remained), since there's a mirror, and adding vertices below that line could probably make accidentally troubles in the mesh, without it.
