 Two of the most common mesh modeling tools in any package is of course the extrude and inset tools in blender These are both quite easy to use The extrude tool is available either from a hotkey or from the toolbar here via the extrude region and extrude individual And I'll go over both of these in just a moment But first let's just make a very basic selection while in face select mode to take a look so I'm just going to select this top face and Let's then hit extrude region and you'll see it has extruded the current selection along the normal So allows us to then just move it up and down automatically and Then as soon as I want to position it wherever I want I can just left click and we're good to go Now a couple things to note first of all if I undo that and then extrude again If I decide that I don't want to do that extrusion and I now just right click one thing to note Is that this has not actually canceled the complete extrusion the reason being is that Extrude is actually a macro in blender where it's actually doing two things first It's extruding and then it's activating transform along the normal So when I cancel that extrusion by either right-clicking or pressing escape I'm actually only cancelling the ladder of the macro, which is the transform along the normal now This is both a blessing and a curse Sometimes it's nice because you want to leave it right there and then manipulate it further after the fact But other times you just want to remove it entirely So just be aware that if that is the case just be sure that you undo twice in order to remove any interior or zero Area faces you may have created, but so that's the extrude region tool Extrude individual is quite similar where if we say select these two faces if we are to choose extrude region You'll notice that it extrudes both of those faces joined together just as we might expect However, if I press extrude individual It will actually extrude each one of these faces as a separate extrusion and allow me to transform each of them along their normals So this can be very handy You'll also notice as with most tools in blender that when I perform it I then immediately have some options in here in the operator panel that allows me to adjust Further things so I can adjust the actual offset any way that I wish I can enable mirror editing in the case that I'm working on on a symmetrical mesh I can enable Proportional editing the proportional editing fall off and etc So most of the time you're not going to be working with this but it is available if you wish You can also access this panel by pressing f6 anytime over the viewport and it will show the settings for your last use function So that's the extrude tool quite simple A lot allows you to extrude quite quickly, but this is just so far using the toolbar Most fundamental tools in blender such as the extrude tool are also available via shortcuts And you can see that over the extrude region the shortcut is E So if I select this face and extrude again I can just quickly extrude this just by pressing E moving confirming as many times as I want quite quickly You can also find that the extrude region shortcut key is not actually listed But if you press alt E you actually get a menu to then choose region Which is the default or extrude individual faces so that then you can extrude you know a more complex selection such as the one That we did down here One other way that you can also extrude is if you make a selection and you control left click You can then just extrude along that path quite easily and quickly So another method to quickly extrude your current selection So let's now look at the inset tool the inset tool is Fairly similar if we just say select this section here I'll just select all the vertices and I now hit control F This will bring up my faces menu and the faces menu is also available via the Vertex and edge menus and it's available by pressing control F for faces Control V for vertices or control E for edges You can also find each one of these right here under the measurement So faces edges and normals or faces edges and vertices So in this case, I want to press control F And I can then find inset faces is available right here or it's also available via the hotkey of I So let's just left click here And you'll notice that I can now have move my mouse in and out and allows me to adjust the inset Soon as I do this however, you'll also notice that there's also some settings down here in the bottom of viewport That allow us to adjust the behavior of this for one You can see the confirm is either enter or left click cancel is escape or right click There's the current thickness setting So you'll see that as I adjust the thickness that changes the depth setting Which allows me to actually let's just say I want to scroll this in but then I want to also Offset the depth a little I can then hold down control Temporarily and it will allow me to adjust the depth any way that I want as soon as I release control It will go back to the actual inset or I can also press Oh and it will adjust to create an offset now when I do an offset, you know the depth may kind of Make it a little interesting, but if you can't get your depth back to zero That's okay because you can simply just left click and confirm and then you can adjust anything you want from the operator Panel here so I could go ahead and set the depth back to zero I could say set the thickness to an even one and Maybe I want to instead I want to offset it relative to the current selection or I want the offset to be even So here you can see that these edges obviously are Exactly parallel to their adjacent edges or there's not even and I can choose a boundary selection or not and in this case You won't see this but I'll demo this in just a moment And then we also have the ability to toggle the outset on or off and whether I want to select the outer or the inner So this is just handy as a selection method So that's all fine and dandy, but now let's take a look undo that actually and let's now remove Say these faces so if I select these faces and hit X You'll notice that I have a few more options Then I did when an object mode because I now have the ability to delete vertices Edges faces only edges and faces only faces dissolve edge collapse or edge loop These are fairly self-explanatory But in this case if I just say select faces It's only going to remove those faces and this way these vertices around the edge have been left intact And this is what the inset tool means when it refers to boundaries So if I select I'll just go into face mode for this by hitting control tab and choosing face So let's just select this face right here and then used I for the inset So we'll hit I to bring up our inset and right now It's remembered the last settings that I used so right now it's set to an offset Well, I don't really want to do an offset So I'm gonna press O to go back to my inset And now I can go ahead and just set this in any way that I want and right now it's acting exactly like we would expect it to but if I left click now and Disable the boundary option. You'll notice it's removed this face here And is now no longer taking that boundary into account for the actual inset So this allows you to get good clean insets, you know around the center point of a model or anything like that So that is the inset and extrude tools in blender
