Blender 2.7 Tutorial #5 : Intro To Edit Mode #b3d

hello italo's bar five of these series how to use blender 2.7 in this video i'm going to be introducing you to edit mode within blender which allows you to model custom objects and custom shapes now this is one of the largest areas of blender how to create basically anything you want as a 3d model in a 3d environment to create any object that you want in blender you have to start with a basic mesh and most often this basic mesh is a cube and that's why when you first load up blender blender gives you a cube and your scene to start with you don't have to start with a cube but that's one of the most common ways to start an object because sorry with a cube is called box modeling now to model any shape that you like you have to have a mesh selected and it can be any mesh it can be a cylinder or cone or even a Suzanne monkey head and the way you get into edit mode is with a mesh selected you press tab and when you press tab you switch into edit mode and you can press tab to go out of edit mode alternatively you can always go down to the bottom header bar of your 3d viewport and not actually sure that you can actually see this in youtube so I'm going to just make a second window in case it's cutting the bottom part of the window off on the header of the 3d viewport you can also switch between these two modes on a mesh with this menu you can switch between edit mode in object mode there are many more modes we're not going to talk about those in this video or sticking with edit mode and when you press tab or use the menu to switch into edit mode you'll notice that your header of your 3d viewport will change when you're an object mode you'll see a bunch of squares and a grid these are layers within blender but if you press tab to go into edit mode you'll see four new buttons in place of those grid of layer buttons you'll see a button that is currently selected to be able to select vertexes so with this mode selected you are able to select the points or any two edges meat on the mesh of a model when you go into edit mode you're able to basically edit vertices and the next mode is edges next mode is faces otherwise known as polygons to be able to make any mesh you want into any other shape that you want to be able to edit that mesh so with in edit mode everything in terms of selecting objects is exactly the same if you want to select a face you have to be in face left mode and you can right click on it to select it whenever you have any of the three different sub elements vertices edges or faces selectable or in that selection mode you can right click and select it and then use your gizmo or your keyboard shortcuts s R and G to move rotate and scale or grab rotate and scale that element so if I want to select multiple elements and in other words multiple vertices I can do that with the shift and right click and then I can move those things I can go into I'm just going to press ctrl Z to undo I can go into facelet mode and squash my cube very easily I can scale it to make it more like a pyramid and I can select any of these things that I want and you know move them around and rotate and do any kind of transformation that I want please note though that you cannot scale or rotate a vertex because our vertex is just one coordinate in 3d space it's where two things join you are able to move it in 3d space because it is a coordinate but if I try to rotate it it does nothing ever to scale it with the S key it does nothing as well again because it's just a coordinate so when you're first getting into a blender edit mode you should practice selecting these three things and be able to move and scale them and rotate them and manipulate them as you please the last of these three or four buttons is this limit selection to visible button what the heck does that mean well what it means is when it's dark your object will be solid or not see-through if I click this button to make it light in other words light can now pass through my object and now as you can see I can see the other sides with the back sides of my mesh now my mesh is very simple right now it's just basically a distorted cube which means it only has six lights it only has four six faces rather it only has 12 edges and it only has eight vertices so it's very simple but if I you know how very complicated mesh being able to see through a mesh by default it's not a good idea because you might accidentally select faces in the back when you didn't mean to so it depends what you prefer in what situation you're in whether or not you want to have your mesh solid or see-through with that fourth button so that is an introduction to edit mode the next thing I wanna show you is how to do extrusions but before I do that I'm going to go up to file and new and reload my startup file and we'll start with a default cube again my analogy for using the extrusion or the extrude tool is if we think of this cube as a house my house has four walls and it has a floor and a ceiling so it has six faces or six walls in total and let's say I want to make a garage on the side of my house well I'm gonna press tab to go into edit mode and I'm going to extrude out in other words build upon or make an extension from one of my side walls so if I want to build a garage what I need to do with a face selected in face lock mode is tap E and then move my mouse away from the house and as you can see if I tap to even let go and move my mouse I made an extrusion and when I'm happy with how far away the original qubit is in this case I'll alter a bit right there and I'll click and now I have more geometry here I've extended or extrude out a new set of faces and vertices and edges from my original cube so this is really powerful I can keep going with this in fact you know once you're happy with it or not happy with it you can always adjust it and scale it to your heart's desire but I have to keep going with this and you'll see how extrude will let you make really kind of the basics of any shape that you like if I keep on extruding so I'll press E again now just a warning here if you press E and then right-click that extrusion will be there but it's not pulled out at all right clicking is not really a good idea because it's snaps back your extrusion it's still there but it's hiding and if you just kept on going from that point you'll see that I now have a double edge right here now normally you wouldn't even see the gap between them because it would be snap back to the original location which is what happens when you right-click so if you ever accidentally see extra dots around your edges that means you have hidden geometry and that's bad in a future video I'll talk about how to get rid of duplicate vertices or duplicate faces but for now you should always just press ctrl Z to undo if you see those until they go away all right I'm going to keep going and model a custom shape or an object ina press e again move out a little bit now it's important to note and I'm going to undo that if you press E you can decide how far you want to extrude so I'm now tap to e and now I'm going to tap the number 2 on my keyboard and press Enter what that did is it extruded that face to blender units because the default cube is 2 by 2 by 2 so Y pressing E and then 2 and then enter it made an exact extension of the exact same size of a cube now I want to do that with the middle one but that's ok I'll forgive myself I'm not going to be that accurate in this video so now I'm going to select 3 at the same time and extrude 3 at the same time so we'll shift-click I'll select the second 3 I'll select one and then hold shift and right click the next two if I now press E is going to extrude these 3 as a group and the important thing to know here and I'll press 2 and then enter is that it did not make internal geometry also that again it did not make internal geometry what that means is that there are no internal walls you do not see dots floating in the middle of this these three cubes because I select them all and press E if I had extrude each one of these separately e to enter e to enter you would have seen that if I moved one of these faces around that I actually still do have those internal walls an internal geometry or a total faces is a bad thing you don't want to have internal geometry if you don't mean to have so if you're extruding multiple ones together they will not be internal geometry I'm going to press E and then two and more time to make a three by three by one object and now I'm going to extrude out these bottom four all at the same time because they're separate they will they will just extrude normally and if you can't tell I'm going to make a chair so I'm gonna select these top three if you feel more comfortable not having your mesh in see-through mode then you can do that that way you won't accidentally select background faces and I'm going to extrude these up and as you can see I have a chair now I can press tab to go back into object mode and I can now take my whole chair and scale it and rotate it as one object and I have a chair that I can use in a scene and I can keep adding to it if I want but that's the next thing we're going to talk about now that I have a very blocky shape how the heck do I make this look like a better chair it's a very blocky some would say a Minecraft chair how would I make this better well I'm going to go and restart my scene again so I'm go to file new and reload startup file how can I make this block now return to our house analogy into a better looking customized house because a house would not just maybe have just the same size of a cube extruded to be a garage and maybe there would be like you know different parts of the roof that extrude from different parts of the same mesh the next tool and the last one I want to show you in this video is the loop cut tool and this is a very very powerful tool if I press tab to go into edit mode what I want to do here start to subdivide this shape up and one of the best ways to do that and there are multiple ways to do it is you can press ctrl R and you can do it within any of the three selection modes for to see edges or faces it doesn't matter which mode that you're in if I press ctrl R with in edit mode and put my mouse over the mesh you'll see this pink purple line go all the way around I mash depending on where I put my mouse if you put your mouse over an edge it'll cut or all the way around that mesh with that pink line so what this does is if you then click and then you can move your mouse to decide where your cuts actually going to go if you click a second time it'll make the cut permanent so now I have a mesh with more edges I have more edges that I can play with I can modify my mesh in more ways because I've basically made a subdivide around my mesh through all these phases and now I have many more faces many more vertices and many more edges to play with to make a custom shape I'm going to undo that with control Z I'm gonna do that one more time I'm gonna use a slightly different option this time I'm going to press ctrl R again and I'm going to click because I want to make it around you know this way the way I'm doing it right now and I'm going to click to make that cut permanent but now I get to decide where it goes along this edge just by sliding my mouse when I click it makes this cut permanent but if I right click it snaps it to the middle of these edges so if you want to exactly centered you know front to back in this case or side to side in this case you can just right click instead of left clicking so again control our movie mess around click and then right click to put it in the center of that edge so that's using the loop cut tool but there's even more we can do with it if I press ctrl R to get my loop cut up and I scroll up I can get more cuts now here's a warning this is dangerous you can go really crazy with this and you can add a lot of cuts at the same time I would never do that I would never do more than a few cuts because you know when you're modeling it's not a good idea to make your mesh really complicated before you do anything to it it's a good idea to do things in small steps so I'm just going to make two cuts and then I'm going to right click to put those right in the center and now what I might do is I might select 4 edges and these in this case in fact what I'll do is I'll switch over to a see-through mode and I'll select those 4 which form an edge loop and I'm gonna pull them over a little bit this way now I'm going to select these four edges whoops and move them over this way a little bit now if you're more familiar with linear and a complete beginner net abode you'll know that there are much faster ways of me doing this but I'm just keeping it simple with what we know so far in terms of this video series so now I've got these edges that I can play with in fact I'll make another loop cut around in the other direction right there and I'm going to click and right click and I'm going to pull the roof up of my house so I'm going to pull that one up like that before I do that though I'm actually going to undo I change my mind a little bit I want a garage to come out of my house but I don't want to be the full height of the house so I'm going to make a loop cut around the cube this way and then I'll move it up to right about there so I'm going to make an extrusion from this point that's going to be about where my garage sticks out of my house and now I can move my roof whatever that Pro the roof is called up and so now we're seeing how we can make you know custom shapes by making decisions about how I subdivide up using loop cuts my default cube I want the roof of my garage to be sort of in the same style but I want the edge to be going side to side on my screen right now so I'm going to use ctrl R again and make my cut all the way around the house in this direction so I'll click and then right click to put it in the middle and I'm going to grab this top edge and pull it up right about till there and so as you can see we start with a cube but we're able to make custom shapes I'm going to do one more example of this I'm going to do a control or loop cut around my house in this direction and I'm going to make sort of like a breakfast nook at this side of my house so I'm going to take I'm gonna switch in to face select mode I'm going to take these two faces and I'm going to extrude note a little bit as if I were making a little bit of a breakfast look at the side of my house you can keep going with this obviously I can do a loop cut around the base of my house and I can do a loop cut you know are right about there and loop cut right about there and if I want a step or a pork at the front of my house I can drew that out so as you can see you can start with a cube and quite quickly have something that does not resemble a cube at all this is the basic principle of box modeling we're going to continue this in the next video in which we're going to model something that's not box you like this at all we're going to model a cartoon characters head that's going to be it for this video thanks for watching and I'll see you next time
