Blender | Screws Are EASY Now | Beginners Tutorial

welcome back to another blender tutorial and today i've got something aimed a little bit more at beginners but i'm going to be showing you how to model a simple screw now this might not look like a very um useful tutorial maybe a little bit basic a little bit boring but the principle of making a screw is really useful because it can also allow you to make things like springs and other things that need these iterative little bendy things that go up on a stack that might be hard to model for example like the threads on a screw because they have an offset it's not exactly something that you could model by hand very easily so i'm going to show you how to use blender screw modifier and make this relatively intricate object very very quickly and very easily and show you how you can do the same thing to make a spring or anything that run runs on the same kind of stacked curve stacked angle principle if you will like these little threads that are stacked on top of each other so if there's something you'd like to learn keep watching and i'll show you step by step how to do it in blender with a new scene open blender let's just select all the default objects and hit x and just delete them okay so we want a nice empty scene to get started with we're going to go shift a on our keyboard we're going to go to our mesh primitives and let's just add in a circle now we're not going to be using the whole circle all we're going to simply do is tap into edit mode and we're just going to select the circle to our left or or the vertex to our left so just just one vertex now make sure if you go to your top view okay it's actually this one here so hit seven to go to your top orthographic view or you can just go to view view port and then go to top okay so in your top view just select this vertex and then go control a so sorry control i or command i that's going to inverse the selection select everything else and you're going to hit x and then just delete those verts so the only vert you have is this one right here that should sit right on this x red line here okay so the red axis line you can see it right there now we're going to tab out into object mode and you can see we have one pointer which isn't very interesting but if we now go over to our modifiers and we go over to add modifier we're going to come down and we're going to select the screw modifier you can see over here looks like a screw so we're going to click on it and you can see it's made a full circle here now if you tap into edit mode the only thing you can actually select and edit is that vertex there the rest is just being generated by the screw modifier now if we go back into edit mode and we have this vertex active we can now go e to extrude and then hit z to restrict it to the z axis and let's just bring it up a little bit let's just say about that much okay just for an example and now what we're going to do is we're going to come over here to the screw right now this meter amount determines how much the screw goes up by right so let's just for example let's just make it point eight okay so point eight you can see that's what we have what i'm going to do actually i'm just going to grab this vertex at the top i'm going to go g z and you just bring it up till they touch okay roughly about there and now you can see we actually have the screw part now what we have to come here to is the iteration and iteration will essentially just be the amount of times it uses this offset and stacks it on top right so this would be something to be tricky to model with the screw modifier it kind of does it for you in this cool kind of way so what we can do now is we're going to select both these votes we're going to right click and we're going to click on subdivide and that's going to subdivide one so if we now select this middle vertex as you can see there we can go g and we can go x and move it out into x and look at that now we have a screw right now this is very basic but you can also hit a select everything again you can right click and go subdivide and then you can just select these two new verts like this and you can go g x and move them back a bit now you can create a little bit more of that sort of effect that you see here right so there's a lot of different ways you can do this but the main thing is that you just create the actual little bit here a little bit of geometry that you have to edit so essentially that's all you really have to work with and the modifier does to rest so this is very powerful because it allows you to make very quick changes by just quickly coming in here and moving these around now let's just leave it at that and go back into object mode now all you have to determine is how tall you want to screw so let's just go with something like 12 iterations now there is a million different types of screws out there literally so you can you have really long screws for different applications like ceiling screws for example you have really short ones for putting in like flat boards and stuff so just determine what kind of screw you're looking for for whatever scene you're working on so let's just go with 12 okay i think 12 for this is a good example number maybe maybe 14. i'll make money 14. okay but around there it's good now you're going to notice here there is a little bit of a gap here which is going to be an issue if we add other modifiers so one thing we can do is go into edit mode and just select the top vertex here and we can go g z and just slightly move it up just tiny tiny bit tilde kind of touching and that gap looks close but don't worry if it's not closed because what we're going to do now is we're going to go to add modifier and now we're going to go and get the weld and now you can see that line just disappears it's welding all of that together for us and look at that's all now one piece so let's come to our screw modifier and let's apply it and let's come to our weld modifier and apply that so what it means now if we tap into edit mode this is no longer being generated by a modifier it is now one piece of geometry that's all intact and together look at that imagine if you had to model that um by hand how hard it would be but this just does it all for us pretty cool so now you're probably wondering cool we made the screw part how do you actually make the rest of it so that's really simple okay it might look complicated but it's not so what we're going to do i'm going to start by coming down here and we're going to select all of these verts here so holding and shift you select these ones here the three bottom ones and then holding and shift still we're going to select the last one which is in the corner there i'm going to hit f3 and it's going to come up with a search bar i'm going to type in merge and i'm going to go merge at last now what it's doing is essentially the vertex that we last selected the last active vertex is going to be the one it merges all of that to that looks a bit of a mess but don't worry about that too much we'll fix that in a minute so deselect and i'm going to go shift alt and then just click on an edge down here and it's going to loop select all of these guys like so and now this might be a little bit tricky but just go s and then z and restrict the scaling to the c a little bit and then we're going to go e to extrude and z and bring it down like so i'm going to go s z and flatten it onto z a little bit s z flatten it you can also just go s z 0 and it'll zero it out onto z but i'm just going to go like this i'm going to go s to scale it a bit nng z bring it down s to scale and all i'm doing is just making a point like this you can make your screw as pointy as you want and then with all of those active you can just hit f to fill them and scale it really small or you can just merge all of those verts i'm just going to go with that for now so that looks okay so now you can see we have that part now if you wanted to to make it a little bit more accurate you can select these verts down here and hit g twice and just move them in a bit double g just slide them just so it have has kind of like a little bit of taper that comes around now look at different screws different screws have this more defined in different ways but just look at some references really depends on the screw you're making but something like that is about right okay so you can see that's a very easy way of making a screw now the rest is pretty simple as well same kind of idea we're going to come here to the top select this this vertex holding and shift select these four and then this one last the last one in the corner then hit f3 and once again type in merge and then go to at last and it's la merging it to that last selected active vertex then we're going to go shift alt and click on an edge over here it's going to loop select these and i'm going to go e to extrude and z and move it up and then s z and flatten it onto z like so and now we can go shift alt and s and just round it out just a little bit if it needs it so shift alternates and now we can go e to extrude s to scale make the head as big as you want and then g z move it up a bit and an e to extrude and then z to scale it up and then e to extrude s to scale just a little bit and then we're gonna go control f with all of these still selected these vertex still active we're gonna go shift or sorry we're gonna go ctrl f and we're gonna go grid fill you can come here to the grid fill option and you can mess around with the offset to turn that around so what we want to do is go to our top view and we just want to make sure that this offset down here lines up straight so we got a nice 90 degree line up here as you can see there and that's it so if you wanted to deselect that now all you have to do is select these verts here and go g x just move them down a bit same with these ones and what i like to do just to make a really simple little screw part i just come and go to my face select i just select all of these inward faces here use these guys here and i just go i to insert them a little bit and then e to extrude and z and extrude them down scale them just a tiny bit and that's it that's how i make my really really basic screw now if you're going to really be seeing this up close and you really want a lot of detail go ahead and add extra details but just this basic method here can produce this result really really quickly and it saves you a lot of modeling using modifiers so let's quickly make it look a little bit nicer by adding some more modifiers so i like to add a bevel modifier and i'm going to come here to the segments and i'm going to bump it up to fray and all that's doing is adding a nice little bevel to certain places but if the angle isn't quite right you can come here to the angle and you can mess around with it till you get kind of results that you like something like that looks cool and then let's add a subdivision surface modifier on top of that okay so that's looking actually pretty cool so that's how you make a really cool simple little um screw and i hope you guys have seen the importance of using the sort of screw modifier technique also with the screw modifier you can use the exact same technique to make something like springs i'll quickly give you an example here if we just did the exact same thing you go into edit mode just isolate one vert i'll quickly show you how you can make a spring just give it that same mirror or screw modifier extrude it give it an offset and then give it some more iterations and then you can simply just extrude those verts out along the x and then give it a subdivision surface modifier and now you have a nice simple little spring it really is actually that easy and all you have to do here is mess around with the segments how easy is that so i hope you guys have enjoyed this screw tutorial it was more aimed at beginners but showing you how to take a relatively complicated object it would be hard to maybe model and do it very simply with a modifier i'll see you guys next time for another tutorial and thank you for watching
