Chest Top E -> Alt S Different result

Hi ffighter2g , that will be because your normals are are facing the other way, compared to the video.

Select all (in Edit Mode) and press SHIFT+N to recalculate the normals.

ALT+S scales along the normals, so if the normals are flipped, it scales in the opposite direction.

I've done SHIFT + N, and it didn't help. I turned on normaaN3l visibility and it shows my normals facing correctly.

So what I do know is that when I use alt S, my entire top area of this top part of the chest seems to indent inside, instead of making anything thicker. 

Is E -> Right click to cancel move wrong here somehow? What's going on?

So that's okay then. The minus says it's shrinking and not fattening and that's what you want;)

If it's the other way in the video, then the normals were flipped there, I guess...

I found the "face orientation" button, and yes my normals are inverted. I guess the option to show those little blue lines weren't very clear.

Even with flipping my normals to face the right way, it didn't solve the issue. I still get the same end result. Alt S toward the inside simply pushes my faces inside, instead of making them thicker

This is happening because the 'rounded planks' are connected to the sides. But you scale them separately.

Try this: in edge select mode select the rounded edge loops like this:

Then press V.

Now you can select the rounded planks by hovering over one of the edges and press L.

Go ahead and do what you tried before: E right click (or Escape) and then Alt S.

Extrude the sides separate...

This creates the same issue still. I was also already able to select the rounded planks separately.

I do notice that when he is pressing E in the video he can move it anywhere, while i can only move mine in the Z direction, is there some setting that I'm missing?

I don't know what you are doing wrong.

I followed the exact steps Kent used in the video and got this:

I suggest you start over with the lid and do exactly like Kent. Step by step. Now it probably works.

You've done something wrong somewhere, but I can't figure out where or what.

(Also he couldn't move it anywhere after Extrude, there was a blue line along which he could move it.)

Thanks for the help. I'll try redoing it.

Working now! I don't know what i did wrong before, but now everything is great when i redid the whole thing.

Could be that you had some double vertices (maybe from extruding and then using CTRL Z to undo, which undoes the Transform, but not the Extrude). Then the rounded planks would be connected to those double verts, causing the 'indentation'.

Something like this has happened  to me a lot: I followed a tutorial to the letter, but at a certain point, my results were (completely) different! Then, when I couldn't figure out what I was doing wrong, I just started over and then it worked (usually finding out what I did wrong the first time, by doing it again...)
