Creating Woodworking Joints in SketchUp - The SketchUp Essentials #38

what's up guys Justin here with the Sketchup essentials comm back with another Sketchup essentials tutorial so one of the things that Sketchup is really good for is for modeling things for woodworkers so modeling things at a very high level of precision um you're going to go on you're going to build in the real world partially due to some of the dimensioning tools and other things that are built in so I'm just going to walk you through how to create some basic joints in Sketchup some basic woodworking joints in Sketchup so let's go ahead and just jump into it so the first joint we're going to talk about is a miter joint and that's basically just a joint where you come in here and you've got a couple pieces of wood and you cut them at an angle and then you kind of use them to create a corner just like this and I will say while I'm coming in here and I'm doing this and I'm definitely not a woodworker you know I I don't do a whole lot of woodworking or anything like that but I do know that one of the things a Sketchup is really good for is for working with for working with woodworking drawings and stuff like that so like let's say for example that I've got a piece of wood right here that's 2 inches wide a quarter inch thick just like this and I want to create a miter joint what you're going to do is you're just going to come in here and you're just going to draw a rectangle on the top of this face just like this and you probably want to go until you find the square so in this case that's going to be right here and then all you're going to do is you're going to draw a line from the corner here to the corner here and that will split this and then you can push pull this piece right here and erase this line out and now you've got this 45 degree angle right here you could also come in here with the protractor tool but then all you would do is you would just come in here you would make this a group and you would make a copy of this you can tap the M key for the move tool and you can rotate it just like this and then you can flip it using the scale tool or you could also just use the flip along option if you right click but then you just kind of move this piece just right here and so what you've got is you've got this joint that's at 45 degrees so you create this corner so the next joint we're going to talk about is a half lap and a half lap is basically when you come in and you take about half the material off a piece of wood just like this so you have one piece that has half the material taken off over here you have another piece that has half the material taken off over here and then you just kind of lap them together just like this in order to join those two pieces of wood so in order to do that what you would do is you could come in here you do the same thing you draw your piece of wood just like this and I'm going with two inch pieces of wood i reel two inch wide pieces of wood I realized that actual pieces of wood aren't necessarily always exactly 2 inches but for what we're doing here we can go ahead and do that so let's say that this is a quarter inch thick piece of wood again if you come in here and basically what you would do is you do the same thing you draw a square on the top of this right here just move your mouse until you get a square and then since this piece of wood is a quarter inch thick what you would do is you would push this down by an eighth of an inch just like this so you're taking half the material off of this piece so now you have that piece and you do the same thing we did before where you'd move a copy of this over here you'd go ahead and rotate it and then in this case you could just flip it up and down just like this and then move this piece it's probably best to kind of imprint it over just like this to get everything lined up but then you could just move this piece right on top and you've got your half lap joint just like this so and you can do this with thicker pieces of wood as well my other example over here was more of a half inch thick piece of wood but you can draw your half lap doing that so the next thing we're going to draw is a mortise and tenon and so what that is is that's basically a piece of wood where you cut a slot into a corner piece just like this and then you get a piece of wood and you shave the wood off around a little peg just like this so that when you take these pieces you can put them in just like this in order to create kind of a corner joint and so the way that we would probably do this one the way that we'd probably do this one is we'd start off with our corner piece which I'm going to assume is going to be 4 inches by 4 inches we kind of push pull that up a little bit and probably put that in a group but then what you're going to do is you're going to draw your little wood pieces that are going to come off to the side here like let's say for example that I've got a piece that's going to be an inch wide and we'll say 3 inches tall which may not be a dimensionally you use too much in woodworking but what you would do is you would go ahead and kind of extrude your piece out just like this and then what I would do is I would move it away from this and I would come over here and I would use the offset tool so probably what you would do first is you would figure out how wide you want this piece to be down here so like for example if you take this piece and you figure that this is one inch wide by three inches high you could come in here if you wanted to using offset tool and offset that by probably a quarter inch and what that would do is that would leave you a piece that's a half inch by two and a half inches but if you wanted to get more precise the other thing you could do is you could come in here and you could use the dimension tool to say like for example if you wanted to come off of here a quarter inch on each side you could just draw dimension lines just like this that are a quarter inch off of each side and you could just draw a rectangle just right here and you could push-pull that to whatever you want your length to be so like let's say you wanted that to be an inch long just like this you could use dimensions to come in here and be very precise about the actual dimensions that you wanted this to be but then once you create this piece what I would do is I would come in here and I would make this a group and then I would kind of use the midpoint here to kind of imprints this so that it's lined up with the midpoint on my corner piece and then I would come over here and I would line this up so that it's actually in my piece and then I would right-click and I would say intersect faces with model and then when I do that and I move that away what that did is that intersect my my peg piece right here with my corner piece just like this and so now what I can do and since this is a group I can either explode this or I can copy/paste that geometry in here but what I could do is I could come in here I could erase out these edge pieces but then I could push pull this in by an inch so now what I've got is I've got my piece right here actually modeled so that it has a slot just like this and it's dimensionally correct so if I was to come in here and measure this just like this it would show an inch deep and so then you can kind of do the same thing with this piece over here you could use like the rotate tool in copy mode to make a copy over here and then do the same thing we'll just move this piece in will right click and say intersect faces with model and then we'll move that back we'll probably have to kind of draw over this to make sure this face stayed but we'll just push pull this in by an inch we'll erase the corner here and then you've got your slot on this side as well so you can see how this is going to be a quarter inch down just like what we'd measured it to over here and so the other thing you can do is if you decided for example that you wanted this to be more let's say a half inch down what you could do is you could actually come in here and select all of this geometry just like this and you can actually move your slot down so and you can do the same thing over here you could select all your geometry move it down on the blue axis and imprints it to this point so now all of these are a half-inch down instead of a quarter-inch down and then you can kind of move your slots your AAB pegs down a little bit to kind of line them up and you're good to go and I guess the point of that is to demonstrate that you can come in here and you can kind of adjust the stuff that you create in here if you decide that you want to change your of if you want to change your dimensions and that kind of thing so that's one of the powerful things about using Sketchup for woodworking is you can come in here and you can change stuff like that pretty quick so the next thing you could do is you could do a tonguing groove joint and so the way that you do a tongue and groove joint is you'd come in here and you draw your wood piece so again I'm going to go with a two inch by 12 inch piece just for the sake of simplicity and these pieces might get a little bigger than that but we can go ahead and do this for now so let's say that this is let's say this is a half inch piece of wood just like this what you could do is you can come in here and you could model out basically what you could do on this face is you could divide this in line just like this you can divide this into three segments but then what that would give you is that would give you a length just like this and so what this would do is that would give us a little piece right here that's equally spaced with the pieces above and below that was 3/16 of an inch long when we could draw a 3/16 inch piece over here and then just use the push/pull tool in order to come over here and do this but the other thing you could do before we even do that is you could also move this across your face using copy mode and so now what you could do is you could push pull this piece to the end just like this and then if you double click on this it'll remember the length of the last extrusion that you did and you may have to come in here and heal this face and also kind of flip these faces so the right face is facing outward but if you double-click on that it will extrude that all the way along here to whatever length your last extrusion was and then you can just come in here and you can erase these lines out well then you've got a nice smooth piece just like this now you can make this a group and then you can make a copy just like this and you can see how that groove fits real nicely into that piece so a box joint is a corner joint where you kind of cut these little fingers into the wood just like this so they kind of sit together you probably see this on a whole bunch of wood boxes and that kind of thing but what you could do on this one is you could come in here and you could draw your piece of wood just like this in this case I'm actually going to draw this standing up so all I did is I activated the rectangle tool and I tapped the left key or the left arrow key in order to lock this to my green axis but again I'm going to do in this case we're probably going to do a six inch by 12 inch piece oops we're 12 by 6 so just kind of a taller piece in here just like this I'm actually going to move this down so it's not quite as tall so this turns out to be a 4 inch piece but there's a few different ways you can do this first of all you can extrude this to give it depth so if you've got like a quarter inch piece or a 3/8 inch piece just like this I'm going to put it on 1/4 just because that's a little easier but all you need to do now is you can just come in here you can just measure how tall you want one of these fingers to be so like if you wanted this to be 1/4 inch just like this all you need to do is use the tape measure tool to add these guides just like this so now I've got this in here as a quarter-inch piece well now I can draw I can draw a line in here just like this I can use the Move tool to kind of copy them across just so I've got this in here is like a full rectangular piece and then all you really need to do at this point and there's a few different ways you could do this but I'm going to go ahead and make a copy of all this geometry just like this and then I'm going to push pull this piece over here so that I've got kind of my I've got my kind of like tongue and groove piece in here just like this then all you'd really need to do at this point is you could actually just select all of this geometry and copy it down just like this and then you could type in x 5 or x 6 or x 7 and hit the enter key and that'll just copy that over and over again but what you can do is you can use the push full tool like this and then once you've done it once you can just double-click on a piece and it'll just repeat the same thing that you did last just like this and you can see how what that did is that push pulled all of these well now you can see there's kind of a hole in here all you need to do to fix that is just draw a line across the face just like this and that'll heal all of that geometry and then you can just come in here and you can just erase out these extra pieces just like this so you've got kind of a smooth line along all your little teeth right here and you can do these to any size just just the way that you set your dimensions but then you do the same thing just triple click on this to select everything you'd make a group then you just make a copy just like this then all you need to do is rotate it and you probably need to go ahead and flip it as well so you can select flip along the blue axis just like this because you can see at the top there's a different tooth and at the bottom well if you flip it then you can come in here and you can just line everything up just like this and you can see how this joint lines up pretty much perfectly so that's kind of a box joint and then the last joint we're going to talk about is a dovetail and so a box joint is fairly simple in the sense that these are all rectangular pieces over here but a dovetail is a little more complicated the dovetail is a little more complicated because you can see these are more these are more angled pieces just like this and so what that means is you can't just come in here and draw a box you have to get a little bit more precise with these pieces and then what you would do is you just kind of pop this piece on the end here in order to complete this joint but what we're going to do is we're going to come in here we're going to model our wood piece real quick so in this case we'll go ahead and go with 8 inches high on this one so 12 comma 8 we'll push pull this and again I've just been going with in this case we'll make it a half inch just like this and so what you would do in this case is you would actually come in here and if you look at the way these joints work they go from a wide piece to a narrow piece just like this and so the way that you cannot the way that you can draw those is you can just draw dimension lines just like this so you would draw one two the quarter and then one two the three-eighths and then basically you know the difference here is going to be 1/8 so what we would do in this case is we would come in here and we would draw one piece down at a quarter inch we draw another one down here at 3/8 of an inch and then we could draw another piece down here let's say at a quarter and then we would just move this piece down by another eighth just like this so these are spaced 1/8 of an inch apart this is a space 2 quarter of an inch apart just like this and then all you would do is you would just pull another dimension off depending on how thick you wanted these these pieces to be so like for example if you wanted them to be a half-inch you can pull that here if you wanted them to be a quarter-inch you could set this at a quarter-inch I'm going to go ahead and set them to a half-inch for right now so what you would do in this case is you would just come in here and you would just draw you would just draw lines from the intersections of these points just like this and then you draw a line across and then all you do is you'd push pull this just like this and then the nice thing about doing this is now you could come in here and you can just select this geometry and you can use the move tool in copy mode to create copies of that geometry so you could copy it once and then type in something like x 7 or x 10 something just like that and then you can just push pull these pieces across and when I did that I didn't really necessarily like the way that that looked with how thick this little piece was right here so all I'm going to do is I'm going to come in here and I'm actually going to move this and I'm also going to move my measurement points down by probably an eighth and so that's one of the nice things about Sketchup is you can select this stuff and you can move it down just like that and so you can adjust this stuff really easily so the nice thing about that is I can just come in here and I can just move all of that with copy mode so I can select all of that and then I can move a copy down just like this to that intersection then I can type in time 7 or times 8 and hit the enter key and now make 8 copies of this just like this well then all I have to do is just come in here and push pull these and then once I've done it once again I can come in here and I can just double click to push pull each one of those to whatever the last push pole I did was just like this and then all you have to do is come in here and you can erase out this geometry you can make this a group so then the thing about this one is we're going to treat this one a little bit differently in the sense that we're not going to copy this and rotate it in the same way what we're going to do is we're going to make a copy of it and I'm actually going to take this copy and I'm going to get rid of all my stuff on my in piece right here so I'm just going to come in here and I'm going to delete all of that out so I'm going to delete out all this stuff on the in piece right here because we just want this to act like a board but then all we're going to do is we're going to come in here we're going to rotate this piece to 90 degrees and then we're going to move these pieces so that they intersect just like this so you can see how I took this corner piece and I kind of overlapped it onto this piece right here so if I move this away for example you can see that it's just overlapped geometry so what I'm going to do is I'm going to take this piece right here and I'm going to move it so that it overlaps over this corner and then I'm going to explode it because that seems to be the best way to get the intersect to work so I'm going to explode all of this but then I'm going to come in here and I'm going to right-click on my original piece and I'm going to click intersect faces with model and you can see what that does if I triple click and select this whole thing is that intersects all of this geometry just like this so all my faces now have lines that kind of correspond with these pieces right here well then all I have to do is I can just come in here and I can erase out the pieces that I don't want to keep so in this case you can see how I'm erasing out the leftover pieces where that intersection is going to occur so I'm going to come in here I'm going to erase this piece out I'm going to erase this piece out and you can see how that's leaving a little bit of an overt or a little bit of a hollow piece in here and we'll fill that back in in a second but you can come in here and you can erase all of these pieces just like this I think if I just draw a line all the way up across here it'll heal most of these faces what you're going to have to do is you're going to have to come in here you're going to have to kind of manually fill some stuff in just like this and actually if you do that one time I think that you can just move it down just like this and then type in times for something like times six and you can use that geometry to just kind of fill that in without having to draw all those individual lines so just use the move tool in copy mode but you can come in here and you can erase out this extra geometry over here then you can put that back in a group and now once you kind of slide this back together just like this you can see how you've got these two edges that are in tier as kind of a dovetail joint so the pieces actually fit in here the way they need to go so in this case we use the intersect faces with model so anyway that's for them to wrap up this video I know it got a little bit long I appreciate you guys taking the time to watch this leave a comment below let
