Extruding along normals
I'm trying to extrude a handle to give it more volume, but whenever I'm trying to extrude along normals, it doesn't extrude outwards but instead only on the Z axis. Anyone know what's the problem with this?

I normally use Maya but i'm trying out blender for the first time, feels like i'm completely learning 3D again haha

You are after something like this right?

YEP!!, how do i change my pivot point? is it the orange dot or the red and white circle?

In my screenshot, top center, there are those four buttons/menus. The first one says "Normal" in my screenshot. The button after that with the circles is how you change your pivot point.

Edit: Make sure that is set to "median point" - the alt+s hotkey changes functionality if the pivot point is set to some of (maybe all of) the other pivot point options.

You can right-click with faces selected, then there is an option to extrude along normals. This isn't an operation I normally use so I'm still playing with it. There are a couple other ways to do it - I think. I'll test them and post the other methods inbetween my rounds of Dota.

That's what i'm trying to do but instead of extruding outwards it just extrudes vertically.

For example i'm trying to extrude a normal box with the top face deleted. I then select all face, alt+e and select extrude along normals. instead of extruding outwards so it looks like a box, it just extrudes vertically like a tree lol. That's what i'm having problems with

That might be the problem. Trying to extrude all the faces at once.

Try this instead. Select all faces, hit 'e' to extrude, right-click to let them sit where they are, then hit 'alt+s' to scale along normals. I'm guessing this will achieve the effect you're going for with the extrusion.

Edit: Oh, this is the method for 2.8. The hotkeys to do this might be slightly different if you are still on 2.7.

Edit 2: The alt+s hotkey for scaling along normals isn't working for me now. It did on my first test, not sure why it isn't now. Okay, it was because of changing the pivot point from 'median' to 'individual origins'. If your pivot point is the median point the alt+s hotkey works as I was envisioning.

After selecting the pivot point as Normals, try tapping the axis button twice. For example, if you want to extrude on the Z, tap E (for extrude) then ZZ . You should see the guide lines change each time you tap the extrude axis.

Quick note: I also think it depends on what your trying to extrude and the selection mode your in. For example, if trying to extrude a face and you're in Vertex select mode, the extrude is going to be based on the normals of the selected vertexes, not the face. Same for extruding edges and having the selection mode on vertexes. Your selection mode should be the same as the type of object your extruding as well as having the pivot point set to normals...

Do you mean the transform orientation? There isn't a pivot point option explicitly called normals, but if you do mean to change the pivot point, then I think you mean "individual origins"?

And can you actually extrude all faces of a cube on your end and have them follow each faces' normal? Doesn't seem to work for me on my end.

This is Blender 2.81,,,

And Yes, I meant transform orientations, my bad....
For all faces, let me try
Pte Jack 2019 年 11 月 23 日 下午 1:47 
Hmmm, methods I'm trying seems to separate the cube when I try to extrude all faces at once, grabbing them or scaling... Not sure if this is the same in 2.79 or not.

Hm. That's not what happens when I do it. I simply get a larger box, just as expected. Did you try a completely newly created cube? Just to make sure you didn't make any other changes?
Else a couple of screenshots might help?

I just tried that and it still happening for some reason, and it's only extruding it vertically.

Make sure your pivot point is set to the median point.
