Fundamentals of Blender 2.9+ Through Precision Modeling | What Is Mesh & How To Select It | Part - 5

let's begin the fundamentals of blender what's up  i'm jonathan and welcome to makeup tales where i'm   sharing my makeup journey to help you go further  in yours so don't forget to subscribe and hit that   little bell icon to never miss an opportunity  to keep making this video and a few videos   that follow after it are all about the blender  fundamentals of course it's all going to be done   through the eyes of blender precision modeling and  you're going to learn what exactly is the blender   workflow what is a 3d object within blender made  of and then how on earth do you interact with that   3d object within blender of course this is just  going to be the fundamentals so we'll be starting   very basic and getting a little bit more  complicated within each bite size video   so now let's get on with the blender fundamentals  so here we are within a nice fresh new blender   file now that we have blender set up for our  precision modeling let's go ahead and understand   exactly what we're looking at of course we  know that currently we have this camera here   we have a light there and we have this cube now  let's figure out a little bit more information   here so first off to get a little bit more  information of what exactly is going on in   your scene down on the bottom right hand side  where you've got your version number you can   right click it and put in scene statistics let's  click that and all of a sudden you have all these   statistics of what's going on in your scene now  don't worry about what it says just there i just   want you to see that there it says there's three  objects and it's one of three because we have   our cube selected if we deselect it it's zero okay  fantastic now let's go ahead and observe our cube   in a little bit more detail and our hierarchy so  we know that we have a camera cube and a light our   camera has this little icon next to it very much  looks like a camera our cube has this strange icon   next to it and our light has this other strange  icon well i can tell you that there is a spot   light or a point light and spotlights are a  little bit differently this is a point light   and this here it's got sort of points and  lines between it why is that the case well   blender is something called a mesh modeling  program so this means mesh modeling usually has   two versions to interact with objects within a 3d  space there is the object version and the editing   version now what exactly do i mean by that well  if i select my cube i don't really have any way of   editing this cube currently it sort of just looks  like a cube there's nothing else i can select of   it so if i want to select this face how would i  select that well to do that you have to go into   the editing version so up on the top left you have  object mode which is the current mode we're in   so then to go into edit mode you can do the drop  down to edit mode and now all of a sudden you will   see that our whole cube is selected so let's  click outside of the cube and you'll see that   there's these black points these blue lines and  these gray faces so these blue lines just as we   did right at the beginning when we were setting up  our preferences this was the color blue that i set   these black bits of vertices or a  vertex when you're talking about one   and of course these gray areas are faces so  now you can take a look up on the top right   where your hierarchy is and you can understand  what this symbol is this symbol is the symbol   for mesh because there are vertices and lines  of course it's going to be a little bit tedious   going in and out of edit mode through this  drop down menu so there is a shortcut here   which is the tab button just be aware that you've  got to make sure that you have a 3d mesh object of   some type or a 3d object of some type to go into  edit mode if for instance we click on our camera   and then we hit tab we're not going to be going  into edit mode but if you have your cube selected   and hit tab you will be going into edit mode so  now that we are in edit mode we can see that we   have the black dots like i just said these  are the vertices we have these blue lines   these are your edges and we have these gray  areas which are your faces so right this   minute on the top left you will see that we have  this little box selected this is a vertex select   next to it will be edge select and face select as  you can imagine that means we can currently select   vertices so let's go ahead you can click  on each vertex as so to select it currently   the tool up here is our selection box which is  the shortcut for w you can hit w more than once   and it turns into different types of selections  so just be aware of that so with this one which   is our box selection tool we can make drag a big  box and that will select a whole bunch of vertices   so let's go ahead and let's change this to edges  you can change it by clicking here and this turns   you into the edge selection mode or if you wish to  do it a different way you can use the shortcuts 1   two and three on your keyboard to change between  vertex one edges of two and faces a three   and this is a very quick way of changing your  selection method within edit mode one thing   to keep in mind is if we are for instance in edge  select we select this edge and now we're going to   jump over to vertex select it's going to select  the two vertices that correspond with that edge   the same applies when we go into face select  and we now jump into vertex or edge select is   going to select all the edges or vertices that are  correspondent with that face so now we understand   that a 3d object within blender is made out  of a collection of vertices edges and faces   now these don't need to exactly be connected but  we'll get to that later on in another video for   now i want to go back into edit mode and i want to  show you more selection methods so we now know how   to individually select and box select both edges  faces and vertices but how about deselection well   like many programs out there deselection is  going to be holding down control and then   like a selection so holding down shift increases  your selection and holding down control   decreases your selection so now let's go ahead  and let's select everything that we see here   okay we think that we've just selected everything  one thing to be aware is that you might have   thought you've just selected everything but  this is a three-dimensional object and currently   this three-dimensional object is not how would  i say it isn't acting as a transparent object if   we go to the other side you will see that we have  a vertex that is unselected now there is a quick   way to go ahead and select everything on the scene  to do that you just press a and that will select   everything within a scene of course that very  much means that if you're in edit mode everything   in edit mode will be selected and if you're  in object mode everything will be selected   so now we know how to select everything and  we know how to do a box selection now let's   go ahead and let's show you a few more advanced  selection methods to cover our advanced selection   there's a little file down in the description that  has this blender file i'm going to show you how to   create an object like this later on don't worry  i just want to keep this video to very much just   selection so just download the file down below  and then we'll carry on so this here is something   called a uv sphere if we select it and go into  edit mode you will see that we have a lot more   faces edges and vertices to play around with so  first let's go ahead and cover something called   loop selection as the name applies we are going  to be doing a selection of a loop so first let's   go into face selection with the shortcut of  three let's select a face and now let's say   that i wanted to select all the face around  this edge so let's go ahead and figure out how   to do that well to do that we're going to hold  down alt and go as close to the edge as we can   or certainly close to it so it's obvious and then  when we left click it's going to select that loop   the same applies for wanting to go for the loop  up above but something has changed here why hasn't   gone all the way around the main reason why is  because we have a triangle up here and a triangle   doesn't have a top edge a bottom edge a left edge  and a right edge this is how it's calculating   our loop so we have to make sure that if we're  wanting to do and use loop selection it's very   much that it is a a quad so with that said let's  go ahead and see how loop selection works within   edge mode so now let's go and select an edge hit  alt and click it selected the loop around the ball   fantastic so that's nice and easy same applies  vertically and once again it's not obvious up   here what's going on we can also do this with  vertices we select a vertex go a little bit to   the right of it and click and that's going to do  a loop selection or you can go above it and click   and that will do a loop selection that way so that  there is loop selection next let's take a look at   two things at the same time which is inverting  a selection and increasing a selection so let's   go and click this top vertex here and i let's  say i very much wanted to select all of these   rings that were going down it how would i do that  quickly well the best way would be to increase my   selection to do this i use the numpad plus with  control so control numpad plus increases my   selection and i can use numpad minus to decrease  my selection so let's increase it a little bit   and you know what now i want this to be inverted i  want what's selected right now to be not selected   and what's not selected to be selected very  easy shortcut here which is control i and that   inverts your selection now you can use both of  these within edge mode as well so if we select   these edges here i'm going to hold down shift to  increase my selections a little bit as well and   now i'm going to go ahead and do control i we've  inverted our selection and the same with our faces   so let's go here i'm going to go control plus a  few times and now i'm going to invert my selection   with control i so that there is how to increase  and decrease selections using your numpad as well   as how to invert a selection while we're at it  let me show you two other ways of doing selection   one is called pathway select and the other one  is called circle select so pathway select as   the name sort of implies is that the selection  will be as a pathway so let's select one face   here and let's say i very much want to select the  face over here but i don't want to go ahead and   draw a box selecting all the faces that's going  to take me there well if i hold down control   what it's going to calculate is the quickest face  route to that other selection point so i'm going   to left click and as you see it has selected the  pathway so holding down control i can do click   click and click and click and as easy as that i  have this selection so it's a little bit abstract   pathway selection but it can be useful for  those niche circumstances now let's go ahead   and cover something a little bit different which  is the circle selection it's different because it   doesn't really interact like the other selection  tools so now let's go ahead and hit the shortcut   key which is c for circle selection you will see  that this circle appears around your mouse now   how do i cancel this well i can hit escape or  i can right click and that cancels my selection   just before we go back into circle selection  let's go ahead and turn on vertex selection   and then hit c to go back into circle selection  as it implies it is a circle that you can sort   of paint with so let's hold down left click and  drag this across and you will see that we are   selecting everything that we go over with  now if you're wanting to deselect things   it's not going to be using the control you're  going to be holding down shift and now painting   will deselect you can also do this with the middle  mouse button and you won't have to hold down   shift so that there is the circle selection  tool it can be quite interesting when you're   trying to grab a whole bunch of objects now while  we're here i just want to point your attention   back to the information that we had down here you  can now see that we have a lot more vertices edges   and faces and tris so let's go ahead and see what  happens now when we select something with this   while we select you will see the number down here  increases as we increase our selection the same   will be for decreasing the selection but it's  just a very good informational queue to let you   know what exactly you have selected so if one day  you wanted to just select this one thing over here you can be sure that you've selected just  one vertex without accidentally selecting   more than one let's say you couldn't really  see it around the corner now speaking of not   being able to see things now let's talk about  our most advanced part of selection which is   x-ray selection as the name implies we're about  to go into something called x-ray and x-ray will   basically mean that we have an x-ray view of an  object now this isn't really a selection method is   to do with the way that your viewport changes so  we have views up here on the top right hand side   and for now we're just working in this view here  which is called the solid view so this is for   solid shading it's very much solid because when we  try and do a big selection we are only selecting   that thing and we're not on the other side of  it now there's two things to keep in mind here   we have something here called wireframe and  something here called x-ray first let's go   within solid and just turn on manually with the  button x-ray you will see that now we see through   our object and now when we do a big selection  box we are selecting everything immediately   now you might be asking so why on earth would you  want this other one that's here and what is it for   well this is a wireframe view this shows  you the wireframe it also automatically   turns on x-ray now this is more useful outside  of edit mode so let's go back into solid view   and let's go back into object and now you  will see we don't get to see our wireframe   right this minute but if we wanted to see  all our edges we could go ahead and hit our   wireframe shading now if you don't want it to  be x-ray enabled you can always turn off x-ray   but we still see our wireframe that's  the difference it's a little bit gray   but just get the idea that that's the difference  between x-ray wireframe and solid shading so most   of the time i work with solid shading and  then i use one main shortcut which is alt z   and this turns me into x-ray this is how x-ray  looks like in object mode and if you do alt z   again it turns off x-ray so let's go back into  object edit mode excuse me let's go alt z and now   we can very much select right the way through  our object now keep in mind that x-ray works   with every type of selection method be it our  circle selection to our control plus selection   we can select through an object and now do numpad  plus then go into our circle selection and do a   circle selection over here and then increase  our circle selection then do a shift select and   deselect all that across there then we're going to  go right click to cancel our circle selection then   we're going to go alt z to go back into our solid  view without wireframe you can see our selection   now there is one more shortcut i just want to  quickly say which is shift z this takes you   into our wireframe view and keep in mind that if  you turn off x-ray it will remember that you've   turned it off and if you turn it back on it  will remember that you've turned it back on   within wireframe and with that covered we now have  a basic fundamental blender selection covered as   well as understanding what exactly a 3d object is  made of within blender and starting to understand   the fundamentals of the blender workflow that  there is this object mode and this edit mode   there are two completely different environments  to interact with 3d objects stick to the end for a   little something extra a huge thanks to my patrons  you guys are absolutely awesome and it means the   world to me and if you're enjoying what i'm doing  here and you think i'm worthy of your support   i would love to see you there too don't forget  that we have a discord community and it is linked   down in the description thank you for watching  keep making and let the quest continue and for   you awesome few that have made it all the way  to the end this here is a mini obstacle course   to make sure that you've really understood  the concepts that we've covered in this video   link down below is also a solution video to make  sure that you really understand what's going on
